250 MCM 19 Stranded Bare Copper Conductor Soft Drawn Wire

Other Names For 250-19 stranded bare copper conductors:

250-19 stranded bare copper wire, 250-19 stranded bare electrical wire, 250-19 bare copper ground wire, 250-19 raw copper wire, 250-19 bare earth wire, 250-19 hard-drawn copper wire, 250-91 medium-hard copper wire, 250-19 soft annealed copper wire

Applications:

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
