Download PDF Download Excel Table

Construction:

Conductor:Tinned copper class B or C
Tape:Binder tape for ease of insulation removal
Insulation:Heat, moisture, and ozone resistant Ethylene Propylene Diene Monomer (EPDM)
Jacket:Thermoplastic Chlorinated Polyethylene CPE jacket

Applications and Features:

Southwire’s medium voltage non-shielded cable is intended for use in substations installed on insulators and inside switchgear isolated from ground and where a non-shielded cable is desired. These cables are capable of operating continuously at a conductor temperature not in excess of 90°C. See Table 2 for installation guidelines.

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

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

† Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
† Ampacities have been adjusted for more than Three Current-Carrying Conductors.
* Inductive impedance is based on non-ferrous conduit with one diameter spacing.
