Application
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.
Sprcifications
QINGZHOU's 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-787 19 Wire Combination Unilay-Stranded Soft copper wire.
·B-8 Concentric-Lay-Stranded Hard, Medium-Hard or Soft Copper Conductor
·ASTM B-33 for "Tinned Soft or Annealed Copper for Electrical Purposes
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
