APPLICATIONS
Used for overhead electrical transmission and distribution lines, grounding electrical systems, electrical test equipment and other infrastructure.

CONSTRUCTION
Conductors: Concentric-lay stranded bare copper conductors available in soft, medium hard, or hard temper. Stranded tin coated copper conductors available in soft temper only.

STANDARDS

• ASTM B1 – Hard-drawn copper wire
• ASTM B2 – Medium hard-drawn copper wire
• ASTM B3 – Soft or annealed copper wire
• ASTM B8 – Concentric-lay stranded copper conductors: all tempers
• ASTM B258 – Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors
• Federal Specification QQ-W-343 – Wire, Electrical, Copper (Uninsulated)

NOTES
Dimensions and weights are nominal values, subject to standard manufacturing tolerances. Conductor ampacities are in accordance with the NEC, latest edition.
