DC Solar Cable

After hydro and wind power, the third most important renewable energy source is solar photovoltaic in items of globally installed capacity. This results in the great demand for ‘SOLAR CABLE’. Solar cables are exclusively made for applications in photovoltaic power systems. A solar cable interconnects solar panels and other electrical components of photovoltaic system. These solar cables are designed to be UV & Ozone resistant, Chemical and Oil resistant, with excellent FR properties, propagates smoke with low capacity when burned with external source and contains absolutely ZERO or low halogen. These cable can survive extreme weather conditions. It can be used within a large temperature range and are generally laid outside. These cable can be installed at indoor in hazard area, in explosion areas, in industry and in agriculture. These cables are environment friendly which performs highest standards of application in its diverse usage.

Construction

 

Insulation

Solar cable must be insulated to withstand thermal and mechanical loads. As a consequence, plastics which have been cross-linkable Silicon / Electron Beam feature are increasingly used. The insulation and double jacketed materials are extremely resistant to weathering, UV-radiation and abrasion . Additionally, it is salt water resistant and resistant to acids and alkaline solutions. It is suitable for fixed installation as well as for moving applications without tensile load. It is especially designed for outdoor use, which means direct sun radiation and air humidity, but due to the halogen free flame retardant cross-linked jacket material the cable can also be installed in dry and humid conditions indoors.
