Construction:

Conductor:Class B compressed stranded bare copper per ASTM B3 and ASTM B8 (Tinned Copper per ASTM B33 optional)
Conductor Shield:Semi-conducting cross-linked copolymer; A conductor separator is used for cable size larger than or equal to 500 Kcmil
Insulation:260 Mils No Lead Ethylene Propylene Rubber (NL-EPR) 100% Insulation Level
Insulation Shield:Strippable semi-conducting cross-linked copolymer
Copper Tape Shield:Helically wrapped 5 mil copper tape with 25% overlap
Overall Jacket:Thermoplastic SOLONON® Low Smoke Zero Halogen (LSZH-TP)

Applications and Features:

Southwire’s 25KV cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial when installed with a grounding conductor in close proximity that conforms to NEC section 311.36 and 250.4(A)(5), and where superior electrical properties are desired. 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 at -35°C for cold bend. ST1 (low smoke) Rated for sizes 1/0 and larger. Rated for 1000 lbs./FT maximum sidewall pressure.
