SOLAR CABLES

Solar cables are intended for use in photovoltaic power supply systems and similar applications as free hanging, movable, fixed installation and buried in ground in constructional covered systems. Suraj Cables offers TUV Certified electron-beam cross-linked solar cable under the brand name of SolarCabTM. E- Beam irradiation is a process in which the polymer is exposed to a highly charged steam of electrons that creates cross- linking between the molecules.This cross- linking significantly improves thermal, mechanical and chemical properties of the polymer. Matching step with the environment friendly shift the Solar Cable has been made which performs highest standards of application in its diverse usage.
