Solid and stranded bare copper are suitable for overhead transmission and distribution applications
APPLICATIONS
Solid and stranded bare copper are suitable for overhead
transmission and distribution applications. Stranded conductor of
greater flexibility are suitable for uninsulated hook up, jumpers,
and grounds in electrical construction. Soft Drawn copper is unilay
construction.
SPECIFICATIONS
Bare copper wire and cable meets or exceeds the following ASTM
specifications:
• B-1 Hard-Drawn Copper Wire.
• B-2 Medium-Hard Copper Wire.
• B-3 Soft or Annealed Copper Wire.
• B-8 Concentric-Lay-Stranded Hard, Medium-Hard or Soft Copper
Conductor.
• B-33 Tinned Conductors
• B-787 19 Wire Combination Unilay-Stranded Soft copper wire.
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
