Each product is tested to meet or exceed IS 8130, IEC 60228, ASTM B33, and ASTM B172 international standards. Available in various widths, thicknesses, and current ratings, our braided tinned flat tapes are ideal for both industrial power systems and commercial electrical installations.
What are Braided Tinned Flat Tapes?
Braided Tinned Flat Tapes are flexible electrical conductors made by interlacing fine tinned copper wires into a flat braided structure. The tin coating provides superior protection against corrosion and oxidation, making these tapes essential for earthing, grounding, electrical continuity, and flexible connections in industrial and commercial electrical systems.
Unlike rigid conductors, braided flat tapes offer exceptional flexibility, making them ideal for applications involving vibration, movement, or thermal expansion. They are widely used in switchgear panels, transformers, busbars, automotive systems, renewable energy installations, and lightning protection where reliable electrical performance and environmental resistance are critical.

Comprehensive Technical Specifications
| Property | Specification | Significance |
|---|---|---|
| Conductor Material | High-Conductivity Electrolytic Copper (Individually Tinned Strands) | The copper provides high current capacity, while the tinning provides crucial corrosion and oxidation resistance, ensuring stable, long-term conductivity. |
| Voltage Grade | Low to Medium Voltage (Used mainly for high current/bonding) | Primarily used for equipotential bonding and earthing, meaning the conductor operates at low voltage relative to ground, but the surrounding equipment may be up to medium voltage. |
| Operating Temperature | -40°C to +150°C (Material Dependent) | The high rating is necessary for safely dissipating heat generated by continuous high current or large fault/short-circuit currents common in grounding systems. |
| Construction | Flat Braid (Woven from Fine Tinned Copper Wires) | Defining Feature. The woven flat shape provides extreme flexibility to handle vibration and thermal movement, crucial in busbar systems and switchgear assemblies. |
| Corrosion Resistance | Excellent | The tin layer prevents the fine copper strands from reacting with moisture, industrial gases, and salts, which is vital for use in coastal areas or chemical plants. |
| Termination Ends | Pressed or Welded Copper Lugs/Ferrules | Requires a secure, gas-tight termination to maintain low resistance. Tinned surfaces improve solderability and contact reliability. |
| Key Function | Flexible Grounding, Earthing Jumpers, and Bonding Straps | Used extensively in environments where longevity in harsh conditions and compensation for movement are both required. |
