We are a leading Manufacturer of chemical copper earthing electrode, from Chennai, India. Solid copper ground rods made of high conductive hard drawn bare copper. Owing to our vast experience, we are engaged in providing excellent quality range of Pure Copper Earthing Electrode to our reputed clients. This is tested by our quality controllers in order to dispatch flawless range at client's end.

Due to the inherent softness of the copper material, special consideration should be given when driving this product into the soil.Deep earthing is done in areas where the surface soil resistivity is very high and where attaining desirable earth resistance value is very difficult; our extensible earth electrodes are designed in such a way that, driving of rods to greater depths are made very easy because of its quality craftmanship.

Manufactured by us using the best quality of raw materials available in the market, this Copper Earthing Electrode provided by us is strong and has a long functional life. The offered system finds its application in industries where earthing and maintenance of engineering products is required. Its efficiency, quality, and reasonable pricing make this product highly demanded in the market.

For use in highly-corrosive soils. Stainless steel earth rods are highly resistant to corrosion and a comprehensive range of earth rod driving heads, spikes, dowels and couplers are available. Earth rods are manufactured from stainless steel according to BS EN 10088 standard with excellent corrosion resistance for harsh environmental conditions.

Stainless steel earth rods are designed for use where problems may be caused by galvanic corrosion due to dissimilar metals being buried in close proximity – they are produced from stainless steel rod and are internally threaded for jointing.

Made from austenitic steel to British standards. The stainless steel rod is similar to copper rods but are more anodic than copper and are useful where galvanic corrosion is possible. The current carrying capacity of the stainless steel rod in relation to copper is poor. These rods have a tapped hole at each end which allows them to be joined together by means of a coupling dowel.

CPRI tested and certified copper bonded rod earth electrodes are made of low-carbon steel of superior grade and quality, with a high tensile strength of at least 600N/mm2. 250 microns of copper is molecularly bonded to nickel sealed steel rods to avoid copper to steel merging. This provides ensured performance and double protection as required under UL 467 and IEEE spec which by our in-house testing making sure that our copper bonded rods are excellent in corrosive soil.

Electrode Bending Test Process

TEST PROCEDURES:
A length of the rod shall be rigidly held in a clamp or vice. Applied a force normal to the free end of the rods at a distance from the clamping device equal to 40 times the rod diameter. The application of the force shall be such that the rod is permanently bent through 0 30-degree angle.

RESULT:
There was no cracking of the coating when subjected to the test described above. These different samples were subjected to the above test.

Thickness of Protective Coating Test

PROCEDURES:
The thickness of the protective coating shall be determined by a reliable magnetic coat tester, with the tester hold vertically on the specimen.

RESULT:
The copper coating thickness was measured as 0.25mm or 250 microns at all the points of the rod. Three different samples were subjected to the above tests.

In addition to the above tests, CPRI, Bangalore have conducted short time withstand current tests on two different sizes of copper bonded rods. No cracking or breaking or melting of the rod was noticed after the test. The copper cladding was intact.

Adherence of Coating Test Process

TEST PROCEDURE:
A 467mm (18”) length of rod with one end cut to a 45 degree shall be driven between two steel clamping plates or the jaws of a vice set 1.02mm (0.04 inch) less than the diameter of the rod, so as to shear off sufficient metal to expose the bond between the coating and rod.

RESULT:
There was no separation of the coating from the steel core when subjected to the test described above. Three different samples were subjected to the above test.
