Our LSSSGU-50 3 gauge cable is part of our Mil-Spec Wire and Cable line of Wire and Cable. LSSSGU-50 is composed of a 19/.0526 stranded bare copper conductor with silicone rubber glass tape insulation and a halogen-free (LSZH) cross-linked polyolefin (XLPO) jacket. These cables are rated for a voltage of 1000 volts and an ampacity of 137 at 50°. LSSSGU cable is unarmored, non-flexing, and watertight with surface markings. They are typically used in shipboard power, lighting, or weapon control system interconnection except where unusual circuit parameters require a special type of cable.
