sku: NAYCWY-low-voltage-cables
description: >
  The NAYCWY cable is a shielded low-voltage cable with an aluminium conductor
  and a concentric copper conductor. It has been specifically developed for
  applications requiring additional protection against contact voltages – such
  as in industrial networks, local grids, or power distribution systems.

application: >
  The NAYCWY complies with DIN VDE 0276-603 (HD 603) and is suitable for use in power
  plants, industrial facilities, switching stations, and local networks. It can be
  permanently installed – indoors, in cable ducts, outdoors, underground, or in water.
  Thanks to its concentric conductor, it offers additional protection in case of
  mechanical damage and enables safe potential equalization.

<h3 data-start="540" data-end="595">Designed for increased safety requirements</h3>
<p data-start="597" data-end="998">The <strong data-start="601" data-end="611">NAYCWY</strong> complies with <strong data-start="632" data-end="661">DIN VDE 0276-603 (HD 603)</strong> and is suitable for use in <strong data-start="697" data-end="760">power plants, industrial facilities, switching stations, and local networks</strong>. It can be permanently installed – indoors, in cable ducts, outdoors, underground, or in water. Thanks to its concentric conductor, it offers additional protection in case of mechanical damage and enables safe potential equalization.</p>
<h3 data-start="1000" data-end="1023">Technical construction</h3>
<p data-start="1025" data-end="1497">The electrical conductor consists of <strong data-start="1060" data-end="1073">aluminium</strong>, available as stranded round (RM), sector-shaped solid (SE), or stranded (SM). The <strong data-start="1164" data-end="1185">PVC core insulation</strong> and a <strong data-start="1195" data-end="1228">common EPDM sheath</strong> protect the stranded cores. On top lies a <strong data-start="1278" data-end="1329">concentric conductor made of bare copper wires</strong> with copper tape counter helix – ideally usable as <strong data-start="1372" data-end="1394">PE or PEN conductor</strong>. A black <strong data-start="1422" data-end="1451">UV-resistant PVC sheath</strong> reliably seals the cable from the outside.</p>
<h3 data-start="1499" data-end="1532">Application and special features</h3>
<p data-start="1534" data-end="1894"><strong>NAYCWY</strong> cables are used wherever <strong data-start="1583" data-end="1623">electrical safety and shielding</strong> are required. The concentric conductor does not need to be separated when connecting to branch joints, which simplifies installation. This makes the cable particularly suitable for modern low-voltage networks with increased requirements for operational safety and contact protection.</p>
