The underground solar cable is available for order as bulk material. You will receive 10 meters of cable per piece (for example, 30 meters in total for 3 pieces, etc.). The double-insulated outdoor solar cable features conductor insulation and a black, meter-marked outer sheath made of cross-linked copolymer for enhanced safety during long-term use. The UV-resistant conductor has a reduced outer diameter of 5.2 mm and contains a finely stranded 4 mm² tinned copper conductor. The minimum bending radius of the power cable is 4 times the outer diameter. It is suitable for freely suspended, grounded, and ungrounded photovoltaic systems. It is used for wiring solar modules together as well as for connecting individual module strings and the inverter. The solar energy cable reduces fire spread and smoke gas formation in the event of a fire. An optimized cable design makes the Ölflex cable slim, lightweight, and robust. It can be laid underground within underground protective pipes, ensuring the drainage of water and standing moisture from the cable surface. Conductor color: white.
