DC Solar Photovoltaic Cables

ABOUT

DC Solar Photovoltaic Cables

Solar cables are exclusively made for applications in photovoltaic power systems. A solar cable interconnects solar panels and other electrical components of the photovoltaic system. DC Solar Cable are single core copper cables each for +ve and -ve, They are insulated with cross linkable Low Smoke Zero Halogen compound and sheathed with Low Smoke Zero Halogen compound (Conforming to BS EN 50618:2014 Standard)
