Copper Earthing Clamps
Copper Earthing Clamp – Overview
A Copper Earthing Clamp is a mechanical connector used to securely attach an earth (ground) conductor to a pipe, rod, or structural element, ensuring a safe and low-resistance electrical path to the ground. These clamps are essential in earthing (grounding) systems for electrical safety, lightning protection, and equipment protection.

Key Features
-
Material: High-conductivity copper (≥ 99% purity) or copper alloy.
-
Function: Ensures strong mechanical grip and excellent electrical conductivity.
-
Design: Typically includes a clamp body, fastening bolts, and sometimes a saddle for round surfaces.
-
Conductivity: ≥ 95% IACS (International Annealed Copper Standard).
-
Corrosion Resistance: Resistant to oxidation, moisture, and chemicals, making them suitable for outdoor use.
Common Applications
-
Electrical Earthing Systems – Connects copper conductor to earth rods or pipes.
-
Lightning Protection – Bonds down conductors to earthing electrodes.
-
Industrial Installations – Prevents dangerous voltage build-up in machinery.
-
Marine Environments – Protects systems in ships, docks, and coastal installations.
