We are reckoned as one of the preeminent DPC Copper Wires Manufacturers and Suppliers from India. Double Paper Covered (DPC) Winding Wires are used in winding of distribution transformers universally which is a very important equipment to transport the current.
Testing performed for DPC Copper Wires- Conductor diameter (B.D.)
- Overall diameter (O.D.)
- Electrical Resistance test of Conductor
- Elongation
- Arrangement of layers
Applications- Distribution transformers installed by Electricity Boards / Companies
