Our LSTTOP-5 20 gauge cable is part of our Mil-Spec Wire and Cable line of Wire and Cable. LSTTOP-5 is composed of a 10/30 stranded bare copper conductor with cross-linked polyethylene (XLPE) insulation and a halogen-free (LSZH) cross-linked polyolefin (XLPO) jacket. These cables are rated for a voltage of 300 volts and an ampacity of 4/2 at 50°C. LSTTOP cables are oil resistant, portable, flexing, non-watertight for mission-critical environments. This type of cable is typically used in shipboard interconnect audio, telephone, call bell, announcing and alarm systems.
