SPEC 80150

Bare Copper Wire and Cable

Solid and Stranded

...

Construction:

Bare copper, solid or stranded.
Available in tempers hard, medium-hard, or soft.
Stranded conductors are concentrically stranded in hard and medium-hard tempers and are Combination Unilay stranded in the soft-drawn temper.

Applications and Features:

Solid and stranded (classes AA and A) bare copper are suitable for overhead transmission and distribution applications. Stranded conductor of greater flexibility (classes B and C) are suitable for uninsulated hook up, jumpers, and grounds in electrical construction. Soft Drawn copper is unilay construction.

Specifications:

  • ASTM B1 Hard-Drawn Copper
  • ASTM B2 Medium-Hard Drawn Copper Wire
  • 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
  • Stranded
