Description
Braided Copper Earth Cables are specialized flexible conductors manufactured using high-conductivity bare or tinned copper wires woven into a flat or round braid pattern. The braiding ensures maximum surface area contact, which reduces resistance and enhances current-carrying capacity. This flexible construction allows easy installation even in confined or vibrating environments while maintaining low resistance connections.
These cables are extensively used in switchboards, control panels, electrical machinery, transformers, generators, motors, vehicles, railways, aerospace equipment, communication systems, lightning protection systems, and power distribution units where reliable earthing, bonding, and grounding are paramount for safety, protection against electrical hazards, and effective fault current dissipation.

Technical Specifications
| Property | Specification | Significance |
|---|---|---|
| Conductor Material | High-Purity Electrolytic Copper (Cu-ETP), almost always Tinned (Sn-plated) for longevity. | The high conductivity of copper ensures a low-resistance ground path. Tinning is essential to prevent oxidation and corrosion, maintaining the low resistance required for effective grounding over the cable's lifetime. |
| Construction Type | Ultra-Fine Strands (e.g., 0.05 mm to 0.25 mm) woven into a tubular (round) or flat braid structure. | The braided structure provides maximum flexibility to absorb vibration and thermal expansion, ensuring the ground connection remains intact even when connected components move. |
| Cross-Sectional Area (CSA) | Wide range, typically from 2.5 mm² to 300 mm² (or equivalent AWG sizes). | The CSA dictates the current-carrying capacity and, critically, the short-circuit current rating (Icw) required to handle fault currents safely and prevent catastrophic failure. |
| Insulation/Sheath | Typically Uninsulated (Bare), as the function is to connect two points to the same potential (ground). | Insulation is usually unnecessary for grounding/earthing and is omitted to save cost and space. If a hostile environment dictates protection, a clear PVC or silicone sleeve may be applied. |
| Impedance | Extremely low resistance (DC) and low impedance (AC/RF). | Low resistance is vital for safety (handling fault current). Low impedance (due to the high surface area) is crucial for high-frequency noise suppression and EMI shielding/grounding. |
| Key Function | Safety Earthing, Equipotential Bonding, Fault Current Path, and Vibration Dampening Ground Link. | Used extensively in switchgear, electrical panels, machinery, automotive batteries, and building earth termination networks to ensure a continuous, reliable earth connection. |
| Termination Method | Usually terminated by crimping or welding a solid copper lug (terminal) onto the ends of the braid. | A solid, properly attached lug is necessary to create a large, low-resistance surface area for reliable bolted connection to the earth bar or terminal point. |
| Relevant Standards | IEC 60228 Class 5 or 6 (for flexibility), relevant national/local wiring codes (e.g., NEC, BS 7671) for earthing conductor sizing. | Compliance ensures the cable meets the necessary flexibility requirements and, more importantly, is adequately sized to safely conduct anticipated fault currents to earth. |
Applications
