250 MCM 3C HVTECK Copper 320 mil NLEPR TS AIA 25kV 133% IL Black PVC Jacket CSA

250 MCM 3C HVTECK Copper 320 mil NLEPR TS AIA 25kV 133% IL Black PVC Jacket CSA

Application:

The 25kV HVTECK is a CSA armoured cable for industrial and commercial medium voltage applications. Rated FT4, -40°C, Hazardous Locations (HL). These cables are capable of operating continuously at the conductor temperature not in excess of 105°C for normal operation, 140°C for emergency overload, and 250°C for short circuit conditions. Rated for 1000 lbs /FT maximum sidewall pressure. These cables feature sunlight and moisture resistance, exceptional corona resistance, resistance to most chemical soils and acids and are flame retardant.
