Double-Head Waterproof Solar PV Extension Cable 1000 V / 1500 V (4 / 6 mm²)

Connectors at both ends: the double-head assembly arrives with a mating connector fitted at each end, so an array string can be extended without field crimping and the joint is IP67 sealed from the start. Tinned copper conductor: the tin coating stops the copper from oxidising in the damp, warm conditions inside a rooftop or ground-mount array junction, which is where untinned cable fails first. XLPO insulation with XLPE jacket: the cross-linked insulation and jacket resist the UV, ozone and temperature cycling that a PV cable sees for its whole service life. 1000 V / 1500 V DC: rated for the system voltages used by modern string inverters, in 4 mm² and 6 mm² cross sections. Red and black pairs: supplied as matched red and black leads, in lengths from 1 m upwards, so string layout can be planned without adapters. Compliance: CE and RoHS.
