Soft-Drawn Bare Copper Conductor (ASTM B3/B8)ApplicationsSolid and stranded (classes AA and A) bare copper are suitable for overhead transmission and distribution applications.
Stranded conductor of greater flexibility (classes B and C) are suitable for uninsulated hook up, jumpers, and grounds in electrical construction. Soft Drawn copper is unilay construction.
