Bare Copper Wire

General description

Bare copper cable, hard, medium - hard, or soft drawn.


  • Viakons bare copper cables meet the following specifications:
  • NOM-063-SCFI Electric products - conductors - safety requirements.
  • NMX-J-002-ANCE Hard drawn copper wires for electrical purposes.
  • NMX-J-035-ANCE Medium-hard drawn copper wires for electrical purposes.
  • NMX-J-036-ANCE Soft drawn copper wire for electrical purposes.
  • ASTM B-1 Standard Specification for Hard-Drawn Copper Wire.
  • ASTM B-2 Standard Specification for Medium-Hard-Drawn Copper Wire.
  • ASTM B-3 Standard Specification Soft drawn Copper Wire.


Main applications

  • Copper wires, according to their temper, are used on insulators for electrical distribution lines.
  • For neutral connections and equipment, and for electrical system grounding.


  • The material of the wires is electrolytically pure copper, with a minimum content of 99.9% copper.
  • Manufactured in sizes of 0,051 to 107.2 mm2 (30 to 4/0 AWG).
  • Hard drawn, medium-hard drawn or soft drawn, depending on the application.
  • Offered in the following packages:
  • Coil: Sizes of 5.26 to 33.62 mm2 (10 to 2 AWG).
  • Reel: All sizes.


  • Due to its high electrical conductivity, copper is the ideal metal for electrical installations.
  • Copper conductors are corrosion resistant.
  • Copper wires provide excellent mechanical resistance.
