Application:
Suitable for use in electrical grounding systems (including counterpoise grounding) and on insulators for overhead transmission and distribution applications. Stranded conductors offer greater flexibility than solid.
Standards:
• ASTM Standards:
• B-1 (hard drawn)
• B-2 (medium hard drawn)
• B-3 (soft or annealed)
• B-8 (concentric lay stranded)
• B-33 (tinned)
• B-787 (combination strand)
• REA/RUS Approved
• Federal Standard QQ-W-343
• RoHS Compliant
