Copper Conductor Copper Clad Aluminum CCA Wire Stranded
Product Description
Applications
Solid 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.
