Bare Copper Stranded Conductor

Description

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.

Standard

Hard Drawn Bare Copper Stranded Conductor STANDARD

ASTM B-1 Hard Drawn Copper Wire.

ASTM B-2 Medium-Hard Drawn Copper Wire.

ASTM B-3 Soft or Annealed Copper Wire.

ASTM B-8 Concentric Lay Stranded Copper Conductors, Hard, MediumHard, or Soft.

ASTM B-33 Tinned Conductors

Application

Hard Drawn Bare Copper Stranded Conductor APPLICATION:Bare Copper conductors are primarily used for grounding purposes as specified in the National Electrical Code. Hard-drawn conductors for overhead transmission and distribution lines, as grounding connections in circuits and grounding for machinery or equipment. Soft-drawn solid or stranded conductors, for use as grounding connections in circuits, and grounding for machinery or equipment.
