-**Location:** `ANALYTICS_MIGRATION_COMPLETE.md` (this file)
-- Quick reference guide
-- Deployment instructions
-
-## Quick Start
-
-### Option 1: Automated Deployment (Recommended)
-
-```bash
-# Run the deployment script
-./scripts/deploy-analytics-to-umami.sh
-```
-
-This script will:
-1. Copy files to your server
-2. Provide import instructions
-3. Show you the exact commands to run
-
-### Option 2: Manual Deployment
-
-#### Step 1: Copy files to server
-```bash
-scp data/umami-import.json deploy@alpha.mintel.me:/home/deploy/sites/klz-cables.com/data/
-```
-
-#### Step 2: SSH into server
-```bash
-ssh deploy@alpha.mintel.me
-cd /home/deploy/sites/klz-cables.com
-```
-
-#### Step 3: Import data
-
-**Method A: API Import (if API key is available)**
-```bash
-# Get your API key from Umami dashboard
-# Add to .env: UMAMI_API_KEY=your-api-key
-
-curl -X POST \
-  -H "Content-Type: application/json" \
-  -H "Authorization: Bearer YOUR_API_KEY" \
-  -d @data/umami-import.json \
-  http://localhost:3000/api/import
-```
-
-**Method B: Database Import (direct)**
-```bash
-# Import SQL file into PostgreSQL
-docker exec -i $(docker compose ps -q postgres) psql -U umami -d umami < data/umami-import.sql
-```
-
-**Method C: Manual via Umami Dashboard**
-1. Access Umami dashboard: https://analytics.infra.mintel.me
-2. Go to Settings → Import
-3. Upload `data/umami-import.json`
-4. Select website ID: `59a7db94-0100-4c7e-98ef-99f45b17f9c3`
-5. Click Import
-
-## Your Umami Configuration
-
-**Website ID:** `59a7db94-0100-4c7e-98ef-99f45b17f9c3`
-
-**Environment Variables** (from docker-compose.yml):
-```bash
-NEXT_PUBLIC_UMAMI_WEBSITE_ID=59a7db94-0100-4c7e-98ef-99f45b17f9c3
-NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
-```
-
-**Server Details:**
-- **Host:** alpha.mintel.me
-- **User:** deploy
-- **Path:** /home/deploy/sites/klz-cables.com
-- **Umami API:** http://localhost:3000/api/import
-
-## Data Summary
-
-### What Was Migrated
-- **Source:** Independent Analytics CSV (220 unique pages)
-- **Migrated:** 7,634 simulated page view events
-- **Metrics:** Page views, visitor counts, average duration
-- **Website ID:** `59a7db94-0100-4c7e-98ef-99f45b17f9c3`
-
-### What Was NOT Migrated
-- Individual user sessions
-- Real-time data
-- Geographic data
-- Referrer data
-- Device/browser data
-- Custom events
-
-**Note:** The CSV contains aggregated data, not raw event data. The migration creates simulated historical data for reference only.
-
-## Verification
-
-### After Import
-1. **Check Umami dashboard:** https://analytics.infra.mintel.me
-2. **Verify page view counts** match your expectations
-3. **Check top pages** appear correctly
-4. **Monitor for a few days** to ensure new data is being collected
-
-### Expected Results
-- ✅ 7,634 events imported
-- ✅ 220 unique pages
-- ✅ Historical view counts preserved
-- ✅ Duration data maintained
-
-## Troubleshooting
-
-### Issue: "SSH connection failed"
-**Solution:** Check your SSH key and ensure `deploy@alpha.mintel.me` has access
-
-### Issue: "API import failed"
-**Solution:** 
-1. Check if Umami API is running: `docker compose ps`
-2. Verify API key in `.env`: `UMAMI_API_KEY=your-key`
-3. Try database import instead
-
-### Issue: "Database import failed"
-**Solution:**
-1. Ensure PostgreSQL is running: `docker compose ps`
-2. Check database credentials
-3. Run migrations first: `docker exec -it $(docker compose ps -q postgres) psql -U umami -d umami -c "SELECT 1;"`
-
-### Issue: "No data appears in dashboard"
-**Solution:**
-1. Verify import completed successfully
-2. Check Umami logs: `docker compose logs app`
-3. Ensure website ID matches: `59a7db94-0100-4c7e-98ef-99f45b17f9c3`
-
-## Next Steps
-
-### 1. Import the Data
-Choose one of the import methods above and run it.
-
-### 2. Verify the Migration
-- Check Umami dashboard
-- Verify page view counts
-- Confirm data appears correctly
-
-### 3. Update Your Website
-Your website is already configured with:
-```bash
-NEXT_PUBLIC_UMAMI_WEBSITE_ID=59a7db94-0100-4c7e-98ef-99f45b17f9c3
-NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
-```
-
-### 4. Monitor for a Few Days
-- Ensure Umami is collecting new data
-- Compare with any remaining Independent Analytics data
-- Verify tracking code is working
-
-### 5. Clean Up
-- Keep the original CSV as backup: `data/pages(1).csv`
-- Store migration files for future reference
-- Remove old Independent Analytics plugin from WordPress

-# Environment Variables Cleanup - Summary
-
-## What Was Done
-
-Cleaned up the fragile, overkill environment variable mess and replaced it with a simple, clean, robust **fully automated** system.
-
-## Changes Made
-
-### 1. Dockerfile ✅
-**Before**: 4 build args including runtime-only variables (SENTRY_DSN)
-**After**: 3 build args - only `NEXT_PUBLIC_*` variables that need to be baked into the client bundle
-
-```dockerfile
-# Only these build args now:
-ARG NEXT_PUBLIC_BASE_URL
-ARG NEXT_PUBLIC_UMAMI_WEBSITE_ID
-ARG NEXT_PUBLIC_UMAMI_SCRIPT_URL
-```
-
-### 2. docker-compose.yml ✅
-**Before**: 12+ individual environment variables listed
-**After**: Single `env_file: .env` directive
-
-```yaml
-app:
-  image: registry.infra.mintel.me/mintel/klz-cables.com:latest
-  env_file:
-    - .env  # All runtime vars loaded from here
-```
-
-### 3. .gitea/workflows/deploy.yml ✅
-**Before**: Passing 12+ environment variables individually via SSH command (fragile!)
-**After**: **Fully automated** - workflow creates `.env` file from Gitea secrets and uploads it
-
-```yaml
-# Before (FRAGILE):
-ssh root@alpha.mintel.me \
-  "MAIL_FROM='${{ secrets.MAIL_FROM }}' \
-   MAIL_HOST='${{ secrets.MAIL_HOST }}' \
-   ... (12+ variables) \
-   /home/deploy/deploy.sh"
-
-# After (AUTOMATED):
-# 1. Create .env from secrets
-cat > /tmp/klz-cables.env << EOF
-NODE_ENV=production
-NEXT_PUBLIC_BASE_URL=${{ secrets.NEXT_PUBLIC_BASE_URL }}
-# ... all other vars from secrets
-EOF
-
-# 2. Upload to server
-scp /tmp/klz-cables.env root@alpha.mintel.me:/home/deploy/sites/klz-cables.com/.env
-
-# 3. Deploy
-ssh root@alpha.mintel.me "cd /home/deploy/sites/klz-cables.com && docker-compose up -d"
-```
-
-### 4. New Files Created ✅
-
-- **`.env.production`** - Template for reference (not used in automation)
-- **`docs/DEPLOYMENT.md`** - Complete deployment guide
-- **`docs/SERVER_SETUP.md`** - Server setup instructions
-- **`docs/ENV_MIGRATION.md`** - Migration guide from old to new system
-
-### 5. Updated Files ✅
-
-- **`.env.example`** - Clear documentation of all variables with build-time vs runtime notes
-
-## Architecture
-
-### Build Time (CI/CD)
-```
-Gitea Workflow
-  ↓
-  Only passes NEXT_PUBLIC_* as --build-arg
-  ↓
-Docker Build
-  ↓
-  Validates env vars
-  ↓
-  Bakes NEXT_PUBLIC_* into client bundle
-  ↓
-Push to Registry
-```
-
-### Runtime (Production Server) - FULLY AUTOMATED
-```
-Gitea Secrets
-  ↓
-  Workflow creates .env file
-  ↓
-  SCP uploads to server
-  ↓
-  Secured (chmod 600, chown deploy:deploy)
-  ↓
-docker-compose.yml (env_file: .env)
-  ↓
-  Loads .env into container
-  ↓
-Application runs with full config
-```
-
-## Key Benefits
-
-### 1. Simplicity
-- **Before**: 15+ Gitea secrets, variables in 3+ places
-- **After**: All secrets in Gitea, automatically deployed
-
-### 2. Clarity
-- **Before**: Confusing duplication, unclear which vars go where
-- **After**: Clear separation - build args vs runtime env file
-
-### 3. Robustness
-- **Before**: Fragile SSH command with 12+ inline variables
-- **After**: Robust automated file generation and upload
-
-### 4. Security
-- **Before**: Secrets potentially exposed in CI logs
-- **After**: Secrets masked in logs, .env auto-secured on server
-
-### 5. Maintainability
-- **Before**: Update in 3 places (Dockerfile, docker-compose.yml, deploy.yml)
-- **After**: Update Gitea secrets only - deployment is automatic
-
-### 6. **Zero Manual Steps** 🎉
-- **Before**: Manual .env file creation on server (error-prone, can be forgotten)
-- **After**: **Fully automated** - .env file created and uploaded on every deployment
-
-## What You Need to Do
-
-### Required Gitea Secrets
-
-Ensure these secrets are configured in your Gitea repository:
-
-**Build-Time (NEXT_PUBLIC_*):**
-- `NEXT_PUBLIC_BASE_URL` - Production URL (e.g., `https://klz-cables.com`)
-- `NEXT_PUBLIC_UMAMI_WEBSITE_ID` - Umami analytics ID
-- `NEXT_PUBLIC_UMAMI_SCRIPT_URL` - Umami script URL
-
-**Runtime:**
-- `SENTRY_DSN` - Error tracking DSN
-- `MAIL_HOST` - SMTP server
-- `MAIL_PORT` - SMTP port (e.g., `587`)
-- `MAIL_USERNAME` - SMTP username
-- `MAIL_PASSWORD` - SMTP password
-- `MAIL_FROM` - Sender email
-- `MAIL_RECIPIENTS` - Recipient emails (comma-separated)
-
-**Infrastructure:**
-- `REGISTRY_USER` - Docker registry username
-- `REGISTRY_PASS` - Docker registry password
-- `ALPHA_SSH_KEY` - SSH private key for deployment server
-
-**Notifications:**
-- `GOTIFY_URL` - Gotify notification server URL
-- `GOTIFY_TOKEN` - Gotify application token
-
-### That's It!
-
-**No manual steps required.** Just push to main branch and the workflow will:
-1. ✅ Build Docker image with NEXT_PUBLIC_* build args
-2. ✅ Create .env file from all secrets
-3. ✅ Upload .env to server
-4. ✅ Secure .env file (600 permissions, deploy:deploy ownership)
-5. ✅ Pull latest image
-6. ✅ Deploy with docker-compose

-## Documentation
-
-- **[DEPLOYMENT.md](docs/DEPLOYMENT.md)** - Complete deployment guide
-- **[SERVER_SETUP.md](docs/SERVER_SETUP.md)** - Server setup instructions (mostly automated now)
-- **[ENV_MIGRATION.md](docs/ENV_MIGRATION.md)** - Migration from old to new system
-- **[.env.example](.env.example)** - Environment variables reference
-- **[.env.production](.env.production)** - Production template (for reference)
-
-## Troubleshooting
-
-### Deployment Fails
-
-1. **Check Gitea secrets** - Ensure all required secrets are set
-2. **Check workflow logs** - Look for specific error messages
-3. **SSH to server** - Verify .env file exists and has correct permissions
-4. **Check container logs** - `docker-compose logs -f app`
-
-### .env File Issues
-
-The workflow automatically:
-- Creates .env from secrets
-- Uploads to server
-- Sets 600 permissions
-- Sets deploy:deploy ownership
-
-If there are issues, check the workflow logs for the "📝 Preparing environment configuration" step.
-
-### Missing Environment Variables
-
-If a variable is missing:
-1. Add it to Gitea secrets
-2. Update `.gitea/workflows/deploy.yml` to include it in the .env generation
-3. Push to trigger new deployment
-
----
-
-**Result**: Environment variable management is now simple, clean, robust, and **fully automated**! 🎉
-
-No more manual .env file creation. No more forgotten configuration. No more fragile SSH commands. Just push and deploy!

-# Analytics Migration Summary: Independent Analytics → Umami
-
-## Overview
-
-Successfully migrated analytics data from Independent Analytics WordPress plugin to Umami format.
-
-## Files Created
-
-### 1. Migration Script
-- **Location:** `scripts/migrate-analytics-to-umami.py`
-- **Purpose:** Converts Independent Analytics CSV data to Umami format
-- **Features:**
-  - JSON format (for API import)
-  - SQL format (for direct database import)
-  - API payload format (for manual import)
-
-### 2. Migration Documentation
-- **Location:** `scripts/README-migration.md`
-- **Purpose:** Step-by-step guide for migration
-- **Contents:**
-  - Prerequisites
-  - Migration options
-  - Import instructions
-  - Troubleshooting guide
-
-### 3. Output Files
-
-#### JSON Import File
-- **Location:** `data/umami-import.json`
-- **Size:** 2.1 MB
-- **Records:** 7,634 simulated page view events
-- **Format:** JSON array of Umami-compatible events
-- **Use Case:** Import via Umami API
-
-#### SQL Import File
-- **Location:** `data/umami-import.sql`
-- **Size:** 1.8 MB
-- **Records:** 5,250 SQL INSERT statements
-- **Format:** PostgreSQL-compatible SQL
-- **Use Case:** Direct database import
-
-## Data Migrated
-
-### Source Data
-- **File:** `data/pages(1).csv`
-- **Records:** 220 unique pages
-- **Metrics:**
-  - Page titles
-  - Visitor counts
-  - View counts
-  - Average view duration
-  - Bounce rates
-  - URLs
-  - Page types (Page, Post, Product, Category, etc.)
-
-### Migrated Data
-- **Total Events:** 7,634 simulated page views
-- **Unique Pages:** 220
-- **Data Points:**
-  - Website ID: `klz-cables`
-  - Path: Page URLs
-  - Duration: Preserved from average view duration
-  - Timestamp: Current time (for historical reference)
-
-## Migration Process
-
-### Step 1: Run Migration Script
-```bash
-python3 scripts/migrate-analytics-to-umami.py \
-  --input data/pages\(1\).csv \
-  --output data/umami-import.json \
-  --format json \
-  --site-id klz-cables
-```
-
-### Step 2: Choose Import Method
-
-#### Option A: API Import (Recommended)
-```bash
-curl -X POST \
-  -H "Content-Type: application/json" \
-  -H "Authorization: Bearer YOUR_API_KEY" \
-  -d @data/umami-import.json \
-  https://your-umami-instance.com/api/import
-```
-
-#### Option B: Database Import
-```bash
-psql -U umami -d umami -f data/umami-import.sql
-```
-
-### Step 3: Verify Migration
-1. Check Umami dashboard
-2. Verify page view counts
-3. Confirm data appears correctly
-
-## Important Notes
-
-### Data Limitations
-The CSV export contains **aggregated data**, not raw event data:
-- ✅ Page views (total counts)
-- ✅ Visitor counts
-- ✅ Average view duration
-- ❌ Individual user sessions
-- ❌ Real-time data
-- ❌ Geographic data
-- ❌ Referrer data
-- ❌ Device/browser data
-
-### What Gets Imported
-The migration creates **simulated historical data**:
-- Each page view becomes a separate event
-- Timestamps are set to current time
-- Duration is preserved from average view duration
-- No session tracking (each view is independent)
-
-### Recommendations
-1. **Start fresh with Umami** - Let Umami collect new data going forward
-2. **Keep the original CSV** - Store as backup for future reference
-3. **Update your website** - Replace Independent Analytics tracking with Umami tracking
-4. **Monitor for a few days** - Verify Umami is collecting data correctly
-
-## Verification
-
-### Check Generated Files
-```bash
-# Verify JSON file
-ls -lh data/umami-import.json
-head -20 data/umami-import.json
-
-# Verify SQL file
-ls -lh data/umami-import.sql
-head -20 data/umami-import.sql
-```
-
-### Expected Results
-- ✅ JSON file: ~2.1 MB, 7,634 records
-- ✅ SQL file: ~1.8 MB, 5,250 statements
-- ✅ Both files contain valid data for Umami import
-
-## Next Steps
-
-1. **Set up Umami instance** (if not already done)
-2. **Create a website** in Umami dashboard
-3. **Get your Website ID** and API key
-4. **Run the migration script** with your credentials
-5. **Import the data** using your preferred method
-6. **Verify the migration** in Umami dashboard
-7. **Update your website** to use Umami tracking code
-8. **Monitor for a few days** to ensure data collection works
-
-## Troubleshooting
-
-### Issue: "ModuleNotFoundError"
-**Solution:** Ensure Python 3 is installed: `python3 --version`
-
-### Issue: "Permission denied"
-**Solution:** Make script executable: `chmod +x scripts/migrate-analytics-to-umami.py`
-
-### Issue: API import fails
-**Solution:** Check API key, website ID, and Umami instance accessibility
-
-### Issue: SQL import fails
-**Solution:** Verify database credentials and run migrations first

 # 100 % erneuerbare Energie? Nur mit der richtigen Kabelinfrastruktur!
 Die Vision ist klar: Ein Europa, das seinen Strom zu 100 % aus erneuerbaren Energien gewinnt. Doch während Solar- und Windparks boomen, hinkt der Ausbau der Stromnetze hinterher. Die Ursache? Eine Infrastruktur, die für fossile Kraftwerke gebaut wurde und mit den neuen Anforderungen nicht Schritt hält.
 💡 Fakt: Ein modernes Stromnetz ist mehr als nur Erzeugung – ohne die richtige Verkabelung bleibt der Strom im Windrad oder Solarpanel gefangen.
 Am Ende geht es nicht nur um mehr Strom, sondern um kluge Netze, die ihn zuverlässig und verlustarm transportieren können.

+# Die Zukunft: Intelligente Netze brauchen intelligente Kabel
 Die Energiewende bedeutet nicht nur, dass wir erneuerbare Energiequellen ausbauen – sie erfordert auch eine grundlegende Modernisierung des Stromnetzes. Die Herausforderungen liegen nicht nur in der Menge des erzeugten Stroms, sondern auch in dessen intelligenter Verteilung. Stromerzeugung aus Wind und Sonne ist volatil, das bedeutet: Mal gibt es zu viel Strom, mal zu wenig. Genau hier setzen moderne Netztechnologien an.
 Ein zukunftsfähiges Stromnetz muss flexibel sein, Lastspitzen intelligent ausgleichen und Energie möglichst verlustarm transportieren. Die Schlüsseltechnologien hierfür sind Smart Grids, Batteriespeicher und intelligente Kabelsysteme, die nicht nur Strom leiten, sondern aktiv zur Steuerung des Netzbetriebs beitragen.

 - **Lastmanagement durch Batteriespeicher:** Energie, die nicht sofort benötigt wird, kann in Batteriespeichern zwischengespeichert und zu einem späteren Zeitpunkt eingespeist werden. Die richtige Kabelinfrastruktur sorgt dafür, dass dies effizient und verlustfrei geschieht.
 - **Moderne Kabel mit verbesserten Isolierungen und Materialien:** Hochwertige Kabel mit optimierten Querschnitten reduzieren Übertragungsverluste und tragen so zu einer effizienteren Energienutzung bei.
 - **Dezentrale Energieverteilung:** Statt zentraler Großkraftwerke speisen heute unzählige kleine Erzeuger ins Netz ein. Dies erfordert eine neue Generation von Mittel- und Niederspannungskabeln, die diese Lastverteilung flexibel bewältigen können.
 
 Die Zukunft gehört Netzen, die nicht nur Strom transportieren, sondern ihn aktiv steuern. Dazu braucht es nicht nur mehr Kabel, sondern auch die richtigen Kabel mit intelligenter Technik.

+## Diese Kabeltypen setzen den Standard in Windkraft und Photovoltaik
 Wer Wind- oder Solarstrom einspeisen will, braucht verlässliche Verbindungen – und damit Erdkabel, die sich in der Praxis bewährt haben. Drei Typen stehen dabei besonders häufig auf der Materialliste von Projektplanern und Bauleitern.
 <h4>NA2XS(F)2Y – Mittelspannung für ambitionierte Projekte</h4>
 Dieses Kabel kommt bevorzugt dort zum Einsatz, wo Windkraftanlagen an die Mittelspannungsebene angeschlossen werden. Es ist robust, belastbar und für gängige Verlegearten im Außenbereich ausgelegt. Häufig genutzt zwischen Turbinen und Trafostation – besonders bei mittleren bis großen Anlagen.
 <h4>NAYY – der Klassiker für Niederspannung</h4>
 In Solarprojekten oder im Umfeld von Trafostationen ist dieser Kabeltyp eine wirtschaftliche Lösung. Einfach zu verlegen, gut verfügbar und für viele Niederspannungsanwendungen absolut ausreichend – besonders dort, wo keine extremen Belastungen zu erwarten sind.
 Die genannten Kabel sind bei KLZ in vielen Querschnitten **lagernd verfügbar** – bei Bedarf einfach [hier anfragen](/contact/).
-### Worauf es beim Einkauf wirklich ankommt
+## Worauf es beim Einkauf wirklich ankommt
 Ein gutes Kabel zu finden ist das eine – das richtige auch zu bekommen, wenn man es braucht, ist nochmal eine ganz andere Geschichte. Denn selbst der beste Kabeltyp nützt nichts, wenn Lieferzeiten aus dem Ruder laufen oder technische Details nicht zur Planung passen.
 Entscheidend ist daher nicht nur das Produkt selbst, sondern wer es liefert – und wie.
 Was beim Einkauf von Erdkabeln für Wind- und Solarprojekte besonders zählt:
 – **Verfügbarkeit prüfen**: Welche Querschnitte und Längen sind kurzfristig lieferbar?<br />– **Technische Spezifikation abgleichen**: Stimmen Isolationsklasse, Aderanzahl und Aufbau mit der Planung überein?<br />– **Liefertermine realistisch kalkulieren**: Gerade bei Bauprojekten mit engem Zeitfenster sind Pufferzeiten Gold wert.<br />– **Ansprechpartner mit Fachkenntnis**: Wer Kabel nicht nur verkauft, sondern auch versteht, spart Ihnen am Ende viel Abstimmungsaufwand.
 Ob Mittelspannung oder Niederspannung – eine klare Kommunikation mit dem Lieferanten bringt meistens mehr als zehn Seiten Produktspezifikation. Und ja, ein schneller Blick ins Lager kann nie schaden.
-### Lagernd oder Lieferzeit? Wie wir Kabelverfügbarkeit garantieren
+## Lagernd oder Lieferzeit? Wie wir Kabelverfügbarkeit garantieren
 Projektpläne kennen selten Pausen. Genehmigungen kommen plötzlich, Baugruben sind schneller fertig als gedacht – und dann fehlen die Kabel. Genau hier entscheidet sich, ob ein Projekt in Fahrt bleibt oder ins Stocken gerät.
 Bei KLZ setzen wir auf eine Lagerstrategie, die viele Engpässe von vornherein vermeidet. Statt „just in time“ heißt es bei uns oft: **„liegt schon bereit“**.
 Was das konkret heißt:<br />
 – Gängige Typen wie **NA2XS(F)2Y**, **N2XS(F)2Y** und **NAYY** in den meistverwendeten Querschnitten sind kurzfristig abrufbar.<br />– Auch Sonderlängen oder typische Baurollen für Wind- und Solarprojekte halten wir auf Lager.<br />– Für Projekte in Deutschland und den Niederlanden erfolgt die Lieferung meist innerhalb weniger Tage – direkt auf die Baustelle.
 Das minimiert nicht nur das Risiko teurer Standzeiten, sondern sorgt auch intern für mehr Planungssicherheit.
 Wer früh weiß, was gebraucht wird, kann sich schon vor der eigentlichen Bestellung ein Bild machen – oder eben einfach mal [nachfragen](/contact/), was gerade verfügbar ist.

+## Fazit: Mit den richtigen Kabeln kommt Ihr Projekt schneller ans Netz
 Erdkabel sind das stille Fundament der Energiewende. Keine Schlagzeilen, keine Rotorblätter, keine glänzenden Solarpanels – und doch ist ohne sie alles nichts. Gerade bei **Onshore-Windparks** und **großen Photovoltaikanlagen** entscheidet die richtige Kabellösung über Erfolg oder Frust am Ende der Bauphase.
 Was sich in den letzten Jahren gezeigt hat: Die meisten Projekte scheitern nicht an der Technik, sondern an Verfügbarkeit, Abstimmung und schlechter Vorbereitung. Der Kabeltyp passt nicht zum Einsatzzweck, das Material kommt zu spät, oder es fehlen auf der Baustelle schlicht die passenden Längen.
 Das lässt sich vermeiden – mit Planung, mit Marktkenntnis und mit einem Partner, der weiß, worauf es ankommt. Bei KLZ liefern wir nicht nur Erdkabel, sondern auch die Erfahrung aus zahlreichen Projekten in Deutschland und den Niederlanden. Und weil wir wissen, dass Zeit oft die knappste Ressource ist, haben wir die gängigsten Typen wie **NA2XS(F)2Y**, **N2XS(F)2Y** und **NAYY** in relevanten Querschnitten auf Lager – sofort abrufbar, auf Wunsch direkt zur Baustelle.
