  2. Conductor Shield:Conventional Semi-conducting cross-linked copolymer; Supersmooth conductor shield optional; A conductor tape is used for cable size larger than or equal to 1500 Kcmil
  3. Insulation:420 Mils Tree Retardant Cross Linked Polyethylene 133% insulation level
  4. Insulation Shield:Strippable semi-conducting cross-linked copolymer
  5. Concentric Neutral:Helically applied soft drawn bare copper one-third concentric neutral
  6. Overall Jacket:Linear Low Density Polyethylene (LLDPE) Jacket, Black (red extruded stripes optional); PowerGlide® LLDPE jacket optional

Applications and Features:

Southwire's 35kV cables are suited for use in wet and dry areas, conduits, ducts, direct burial, sunlight, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation. 130°C for emergency overload, and 250°C for short circuit conditions. Jacket types available that can be installed in conduit without the aid of lubrication. Rated for 1000 lbs./FT maximum sidewall pressure.
