Conductor: The conductor is class “K” stranded in accordance with ASTM B172. The wires are soft, annealed copper with a continuous coating of tin (98.0% conductivity) in accordance with ASTM B33. The conductor resistance meets the requirements of ICEA S-95-658 (NEMA WC70).
Insulation: Low smoke silicone rubber to comply with appropriate specifications (see chart on back). The insulation fits the conductor tightly but is “clean stripping.” An opaque polyester tape or other suitable separator is used over the conductor.
Jacket: Flame retardant, low smoke non-halogen and oil resistant crosslinked polyolefin (XLPO) jacket (see chart on back). The jacket is bonded to the EPR insulation.
Applications: These are single conductor 600 and 2000 volt power cables designed for low-smoke environments such as tunnels and subway systems. They consist of silicone rubber insulated conductor jacketed with a tough low smoke zero halogen (LSZH) crosslinked polyolefin (XLPO) jacket. They are highly heat, oil and moisture-resistant, extremely tough yet Flexible, and can sustain 125°C operating temperatures.
