Copper Wire Range (3 products)

Bare Copper Wire
High purity bare copper wire for earthing, electrical connections and conductor manufacturing. 99.9% electrolytic grade copper. Available in round and bunched stranded forms from 0.5 sq mm to 50 sq mm. Used extensively by panel builders, transformer manufacturers and electricians.

Tinned Copper Wire
Electrolytic copper wire with a uniform tin coating for superior corrosion resistance and solderability. Used in marine wiring, humid environments and wherever soldering is required. The tin coat prevents oxidation and ensures reliable long-term connections. Sizes 0.5 to 50 sq mm.

Copper Earthing Wire (EC Grade)
EC (Electrical Conductivity) grade copper earthing wire for proper grounding of electrical installations as per IS 3043. Available in solid and stranded construction. Ensures low impedance earth path to protect personnel and equipment from fault currents.
About Our Copper Wire
Good earthing is the most important safety feature in any electrical installation. A low-resistance copper earth path makes MCBs and RCCBs trip quickly during a fault, protecting people and appliances.
Common Applications
- Earthing pits and equipment grounding
- Panel and switchboard bus connections
- Transformer and motor rewinding workshops
- Marine and humid environments (tinned)
Copper Wire — Frequently Asked Questions
Why use tinned copper wire instead of bare copper?
The tin coating protects copper from oxidation and corrosion, and makes the wire easier to solder. It is preferred in humid, coastal and marine installations.
What size copper wire should I use for earthing a house?
Household earthing commonly uses 2.5 sq mm to 4 sq mm copper earth conductors for circuits, with heavier conductors to the earth electrode. Follow IS 3043 and your electrician's design for the exact sizes.
