The 6mm/10 AWG DC solar cable is made of conductive copper with cap to ensure good conductivity. The solar box uses PP insulation material, aging resistant, ultraviolet ray resistant is excellent. Professional photovoltaic extension cable, TV, CE certification, section: 6mm, temperature range: -45 C + 85C, test voltage: 6500V (rated voltage DC 1500V), line resistance: (20C) 5.09 Q2/km, weather resistance: UV, rated current: 50A. Solar panels with Photovoltaic sockets (red + black) can be used directly, it is not necessary to install cables and sockets by yourself, and it is not necessary to buy additional outlets. Two solar extension cables with PV connectors are connected to a solar panel on one end and a solar charger controller on the other end. Do not cut the closure of the cable or plug. If you are not satisfied with our products, you can support an unconditional refund. Polyaldehyde, fire insulation materials, conductive components, copper materials, waterproof IP68, high tightness , resistant to dust and rain, designed for extreme temperatures and cold, designed for solar photovoltaic systems, suitable for extreme weather conditions, can be buried directly underground. < p>
