Construction

What it is and what it is for

A single-core DC cable for photovoltaic systems, with an annealed tinned copper conductor and cross-linked polyolefin (XLPO) zero-halogen insulation and sheath. It is UV resistant, TÜV certified and conforms to EN 50618.

Solar cable lives on a hot roof for twenty-five years or more, in full sun and rain. Ordinary PVC wire hardens and cracks under that UV and heat. Tinned copper resists corrosion at the connectors, and XLPO stays flexible.

  • Ground-mounted solar plants
  • Solar pumps and street lights
  • Battery and inverter DC links
