Construction:

Conductor:Moisture blocked class B compressed Aluminum ASTM B231 1350 ¾ hard H16/H26 ( Non Moisture Blocked Optional )
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
Insulation:320 Mils Tree Retardant Cross Linked Polyethylene 133% insulation level
Insulation Shield:Strippable semi-conducting cross-linked copolymer
Concentric Neutral:Helically applied soft drawn bare copper one-third concentric neutral
Overall Jacket:Linear Low Density Polyethylene (LLDPE) Jacket, black with red extruded stripes; PowerGlide® LLDPE jacket optional

Applications and Features:

Southwire's 25kV 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.

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 (Qualification Test Requirements)
