Polyolefin Copolymer electron-beam cross-linked Twin PV Cable

Twin Solar cable is designed especially for the interconnection of the various elements in photovoltaic systems. It provides the optimal connection between the solar cells and from the solar cells to the inverter or DC main cable. This Solar cable has been tested to last 25 years. It is also ozone-resistant, UV-resistant, demonstrating its high quality and suitability for purpose. Due to its halogen free, flame retardant and low smoke properties, the cable will not give out toxic emissions in the event of a fire.
