Earth Rod Clamp
Earth Rod Clamps, specifically copper G clamps and copper A clamps, are essential components designed to provide secure electrical and mechanical connections between earth rods and conductors. G clamps are used for joining earth rods to stranded copper conductors, while A clamps connect earth rods to copper tapes. These clamps consist of high-strength copper alloy bodies with stainless steel hardware, offering excellent corrosion resistance and conductivity.
The installation of Earth Rod Clamps involves securing them to earth rods using the appropriate torque specifications, typically 12-15 Nm, ensuring proper contact between the conductor and rod. G clamps accommodate various sizes of stranded copper conductors, while A clamps are designed for different widths of copper tape. These clamps are crucial components in residential, commercial, and industrial grounding applications, including lightning protection systems and electrical installations.
Key Features:
• High copper content alloy body for superior conductivity and corrosion resistance
• Compatible with various conductor sizes and earth rod diameters
• Simple installation requiring minimal tools
• Meets international standards for earthing connections
• G clamps for stranded copper conductors, A clamps for copper tapes
• Designed for long-term reliability in grounding systems

Frequently Asked Questions (FAQ)
What is a Copper Earth Rod Clamp?
What is a Copper Earth Rod Clamp?In Rax Industry, specialized copper connectors are available in two types: G-clamp for connecting stranded copper conductors to earth rods, and A-clamp for connecting copper tape to earth rods. Both are manufactured from high-quality copper for maximum conductivity and corrosion resistance.
What are the differences between G-clamps and A-clamps?
G-clamps are designed specifically for stranded copper conductors, featuring a rounded channel for cable fitting. A-clamps have a flat channel designed for copper tape connections. Both types are made entirely of copper for optimal conductivity.
How are copper earth rod clamps installed?
Installation involves placing the clamp body around the earth rod, inserting the conductor or tape, and tightening the bolts to the specified torque. Ensure all contact surfaces are clean before installation for optimal electrical connection.
How do you ensure proper connection with copper clamps?
Clean all contact surfaces before installation, position the conductor or tape properly in the channel, and tighten bolts evenly. The all-copper construction ensures consistent electrical conductivity throughout the connection.
What are the advantages of all-copper clamps?
All-copper construction provides superior conductivity, excellent corrosion resistance, and eliminates the risk of galvanic corrosion. These clamps maintain their electrical properties throughout their service life and are ideal for long-term grounding applications.
