How to purchase PV cable in a correct way

 In fact, during the installation and maintenance of PV cable in the roof structure of the sharp edge of the wiring, while the cable is exposed to pressure, bending, tension, and strong cross impact tensile load, if the cable sheath strong enough, the cable insulation will be severely damaged, thus affecting the entire cable life, or cause a short circuit, fire and risk of personal injury and other problems.

The radiation cross-linked material, with high mechanical strength yhegty3 #. Cross-linked polymer technology has changed the chemical structure of fusible thermoplastic material into non-fusible elastomer material, the radiation cross-linked significantly improved cable insulation materials, thermal properties, mechanical properties and chemical properties of UL wires.
