Tinned Copper – Stranded

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 temper only.
Tin Coating: A soft drawn conductor is either hot dipped or electroplated with tin. This process significantly improves corrosion resistance.

STANDARDS

• ASTM B3 – Soft or annealed copper wire
• ASTM B8 – Concentric-lay stranded copper conductors, all tempers
• ASTM B33 – Tinned soft or annealed copper wire
• 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.
