Construction:

  1. Conductor:Class B compressed stranded soft drawn bare copper per ASTM B3 and ASTM B8; Conductor moisture block (optional)
  2. Conductor Shield:Conventional Semi-conducting cross-linked copolymer; A conductor tape is used for cable size larger than or equal to 1500 Kcmil
  3. Insulation:445 Mils Ethylene Propylene Rubber (EPR) / Ethylene Alkene Copolymer (EAM) 100% 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 46kV 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 105°C for normal operation. 140°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.

Specifications:

  • ASTM B3 Soft or Annealed Copper Wire
  • ASTM B8 Concentric-Lay-Stranded Copper Conductors
  • ASTM B33 Standard Specification for Tin-Coated Soft or Annealed Copper Wire
  • ICEA S-94-649 Standard for Concentric Neutral Cables Rated 5 - 46kV
  • AEIC CS-8 Specification for extruded dielectric shielded power cables rated for 5 through 46KV (Qualification Test Requirements)
  • Optional CSA 68.5: -40ºC and MV 90ºC optional marking available upon request
