Our LSSSF-300 300 gauge cable is part of our Mil-Spec Wire and Cable line of Wire and Cable. LSSSF-300 is composed of a 259/.034 stranded bare copper conductor with ethylene propylene rubber (EPR) insulation and a halogen-free (LSZH) cross-linked polyolefin (XLPO) jacket. These cables are rated for a voltage of 600 volts. LSSSF cables are unarmored, non-watertight, and flexing, making them useful in mission-critical environments.
