Application

ASTM B8 bare stranded copper conductor for overhead transmission and distribution lines (hard-drawn), grounding electrode conductors, bonding conductors for electrical circuits/systems, substation grounding grids, and equipment grounding. Soft-drawn available for grounding connections. Annealed copper provides high conductivity.

Core Strengths

Critical grounding circuits need maximum conductivity and corrosion resistance. Our bare copper conductor uses high-conductivity annealed/EC-grade copper per ASTM B8. Hard-drawn for overhead lines, soft-drawn for grounding. Excellent termination reliability. CE/TÜV/ISO. Factory direct.

Standard

ASTM B1 , ASTM B2, ASTM B3, ASTM B8
