Construction:

Conductor:Flexible rope lay stranded annealed bare or tinned copper
Conductor Shield:Nylon semi-conducting tape, helically applied
Insulation:Heat, moisture, and ozone resistant Ethylene Propylene Rubber(EPR)

Applications and Features:

Southwire’s medium voltage non-shielded jumper and switchgear cable is a flexible power cable that is intended for use in substations installed on insulators and inside switchgear isolated from ground and where a non-shielded flexible cable is desired. These cables are capable of operating continuously at a conductor temperature not in excess of 90°C.

This cable is rated up to 40KV and is not UL listed. See Table 2 for installation guidelines

Specifications:

ASTM B33 Standard Specification for Tin-Coated Soft or Annealed Copper Wire

ASTM B172 Standard Specification for Rope-Lay-Stranded Copper Conductors Having Bunch-Stranded Copper Conductors
