Construction:

  1. Conductor:Moisture blocked class B compressed Aluminum ASTM B231 1350 ¾ hard H16/H26 ( Non Moisture Blocked Optional )
  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 Ethylene Propylene Rubber (EPR) 133% insulation level
  4. Insulation Shield:Strippable semi-conducting cross-linked copolymer
  5. Concentric Neutral:Helically applied soft drawn bare copper full concentric neutral
  6. Overall Jacket:Linear Low Density Polyethylene (LLDPE) Jacket, black with red extruded stripes; PowerGlide® LLDPE jacket optional

Applications and Features:

Southwire's 35kV 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-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
  • UL 1072 Listed as MV 90 When Specified
  • Optional CSA: CSA 68.5 and -40C optional marking available upon request
