Specification

4-7 Stranded Bare Copper Conductors

Other Names For 4-7 stranded bare copper conductors:

4-7 stranded bare copper wire, 4-7 stranded bare electrical wire, 4-7 bare copper ground wire, 4-7 raw copper wire, 4-7 bare earth wire, 4-7 hard-drawn copper wire, 4-7 medium-hard copper wire, 4-7 soft annealed copper wire

Application:

Stranded Bare Copper Wire (class A) is an electrical wire suitable for overhead transmission and distribution.  Flexible stranded copper wire (classes B and C) is designed for uninsulated hook up, jumpers, and grounds in electrical construction. The wire is uncoated and unalloyed, which lets the customers enjoy the pure benefits of a copper conductor. Bare conductors of this electrical wire exhibit superior conductivity compared to insulated versions.

Construction:

Conductor:

Stranded Bare Copper Wire has a stranded copper conductor per ASTM B-1, B-2 and B-8. The conductor is available in hard, medium-hard, and soft-drawn combination unilay temper. Some of the advantages of copper in cables include conductivity, tensile strength, and the properties of the tensile expansion.

Insulation:

Uninsulated

Jacket:

Unjacketed
