Copper Bonded Earth Rod
254-micron copper bonded steel rods for low-resistance earthing.
Copper Bonded Earth Rod — Overview
India Electricals Syndicate supplies molecularly copper-bonded steel earth rods produced by electro-deposition, where a 254-micron copper layer is bonded to a high-tensile steel core. The result combines the driving strength of steel with the conductivity and corrosion resistance of copper — the standard earth electrode for substation, telecom tower and lightning-protection earthing where decades of buried service life are required.
The 254-micron bonded copper layer delivers greater than 97% IACS conductivity and will not crack or strip during deep driving, unlike clad or plated rods. Rods are threaded and supplied with couplers, driving heads and clamps so multiple sections can be coupled to reach low-resistance strata without splicing the conductor.
Rods are manufactured and tested to IEC 62561 and IS:3043 with NABL-accredited certification available. Material traceability and test reports are supplied against specification. Send your earthing design and target resistance with a quote request for a documented offer from the Howrah desk.

Frequently Asked Questions
What is the copper bonding thickness?+
A 254-micron molecularly electro-deposited copper layer over a high-tensile steel core, giving >97% IACS conductivity.
Why copper-bonded rather than GI or copper-clad?+
The bonded copper will not crack or strip during deep driving and provides far longer buried corrosion life than GI, at lower cost than solid copper.
Can rods be coupled for depth?+
Yes — rods are threaded and supplied with couplers and driving heads to reach low-resistance strata without splicing.
Which standards apply?+
Manufactured and tested to IEC 62561 and IS:3043, with NABL-accredited certificates available against specification.
