Applications and Features:

Southwire's 46kV cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, 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 B231 Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors
  • ASTM B609 Standard Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
  • ICEA S-97-682 Standard for Shielded Utility Cable Rated for 5 - 46kV
  • AEIC CS-8 Specification for extruded dielectric shielded power cables rated for 5 through 46KV
  • Optional CSA: CSA 68.5 and -40C optional marking available upon request
