### Solar Cables

Connecting the sun’s energy to your sustainable future.

### What we do

We ensure that the electricity flows – with quality-tested cables. From low voltage up to high voltage

###### 01

#### Supply to energy suppliers, wind and solar parks, industry and trade

We support your projects from 1 to 220 kV, from simple NYY to high-voltage cables with segment conductors and aluminum sheaths, with a particular focus on medium-voltage cables. Whether NA2XS(F)2Y in standard design, or up to 1200 mm2 cross-section, with thick sheathing or in the desired lengths. We have partners with an enormous variety.

###### 02

#### Supply of cables whose quality is certified

Cables are products that have to function 100%. For decades, often 80 to 100 years. Our cables are not only approved by VDE. The most well-known energy suppliers in Germany, the Netherlands and Austria trust us and our manufacturers. And often the requirements are even higher than those of the already strict VDE regulations.

###### 03

#### We deliver on time because we know the consequences for you

Wind farm North Germany, coordinates XYZ, delivery Wednesday 2-4 p.m., no unloading option. Yes, we know that. We organize the logistics with a back office team that has up to 20 years of cable experience. Customs clearance and proper paperwork included.

###### 04

#### The cable alone is not the solution

Stony ground? Perhaps a thicker outer sheath would be better? Damp ground? Can there be transverse watertight protection in addition to the longitudinal watertight tape? Longer individual lengths, but no thought given to the limitations of the laying crane? Or often underestimated? What can the floor in the warehouse support? A copper cable can easily weigh 10 tons per kilometer. We think for you and ask questions.

### Decades of experience rooted in cable history

At KLZ, cables run in our veins. Klaus began his journey at the renowned Felten & Guilleaume, following in the footsteps of his parents, who dedicated their lives to the same iconic company. For Klaus, this isn’t just work – it’s a legacy built on craftsmanship, innovation, and pride.

We honor this history with original illustrations from Felten & Guilleaume’s era, once used as postcards. These images remind us of the generations who wired the world together – a tradition we proudly continue today.

### Why choose us

Experience prevents many mistakes, but we learn something new every day

###### 01

#### Expertise with depth

Our team has decades of experience – far beyond the founding of KLZ in 2009. The entire team has over 100 years of cable experience, gained in a wide variety of plants, from low voltage to medium voltage to high voltage. We know what cables smell like, what the colleague at the shielding machine is responsible for how testing is carried out. We know the main raw material manufacturers, know the risks of production, and can compare plants. Whether in old or new buildings. Anyone who has decades of audits and prequalification behind them knows where to look. And what are the right questions.

###### 02

#### Tailor-made solutions for your project

When things get more complex, we involve our technical consultants. That’s where you need experts who haven’t just started their careers. You need people who read and understand standards and have sometimes been involved. We have them, and with their and our experience we differentiate ourselves from simple cable trading

###### 03

#### Reliability that keeps your projects on track

Accessibility, quick response in a fast-moving world. Do you still have questions after 5 p.m.? Or at the weekend? We are always there. And that is how we have developed our partners so that as a team we can realize what you have paid for. And if something does not go well, no one hides.

###### 04

#### Sustainability without compromise

We are convinced that we will leave the world better than we found it. With initiatives such as our drum return service and a clear focus on recycling, we ensure that every connection is as environmentally friendly as possible. Each of our partners has the appropriate certificates, which are increasingly expected by all customers.

At KLZ we focus on precise, reliable and uncomplicated solutions for the energy of the future.
