1.  Earthing Electrode

a.  GI Earthing Electrode:

The metal in GI Earthing Electrode is coated with a layer of zinc. As zinc oxidizes and reacts

with gases in the atmosphere it will eventually form a protective coating of zinc carbonate that

will protect both the zinc and the iron beneath it and thus gives long lasting earthing system. 

1. 

Highly galvanized pipe is used for electrode

2. 

Highly conductive & non corrosive mixture is poured inside the electrode so that inner

strip or pipe will never corrode and provide lowest possible resistance.

3. 

Pipe in pipe / Strip in Pipe technology

4. 

Weight of 40mm dia electrode is > 17.0 Kg, 50mm dia electrode is> 23.0Kg and 80mm

dia electrode is > 45Kg.

b.  Copper Electrode:

Copper is a highly conductive material and keeping this in mind we make use of the

purest form of copper in the manufacture, trade and supply of Copper Earthing

Electrode that provided leak-proof high conductivity and protection. These products

are developed in efforts to provide safety to electrical & electronic machineries and

gadgets especially for use by human beings. 

c.  Copper Bonded Electrodes:

o 

Up to 250 micron CU Bonded on Steel

o 

Life Span: Due to 250 micron CU Bonded life is much more than GI & Cu

Earthing Rodso 

High Conductivity with High Strength

o 

Cost Effective as comparison to life span & CU Rods

o 

Highly Reliable in long Span

o 

Continuous electroplating processing

o 

Variable choices are manufactured as required by the customers

o 

Values over the life of the product

o 

Reduced installation area and time

d.  Copper Bonded Rods:

Copper Bonded Earth Rods are molecularly bonded with 99.98% pure Electrolytic grade Copper ovea low carbon tensile steel rod with the thickness of 254 micron copper coating. We are also able to

deliver customized copper thickness between 100 microns to 330 microns. All the raw materials

used in the Composition strictly comply with the certified standards. The carbon tensile steel

complies with BS 970 & AISI 1018 and has a great capacity of being stretched or extended at least

up to 600 N/mm2. The copper used in manufacturing these earthing rods conform to BS 4360 grade

43A. In order to prevent oxidation of copper bonding each rod is treated with advanced technologies.

In comparison to steel rods, in the extreme soil condition (such as high salt or moisture content) the

copper provides high corrosion resistance and exceptionally long life. The bonding of copper layer to

steel core via an electrolytic process ensures a perfect and tough bonding between the steel and the

copper.

2.  Back filling Compound (Earth enhancing chemical)

LOHM is an advanced backfill compound, which lowers the contact

resistance of the earth electrode to earth by over 60%. It produces

low impedance to surges resulting in faster transient dissipation. It is

RoHS compliant and has excellent shelf life. It performs in all soil

conditions even during dry weather, does not depend on continuous

presence of water, requires no maintenance and does not adverselyaffect soil or ground water. It is available in easily transportable 10/

25 Kg. bags. Resistivity of chemical is less than 0.1 ohm-m. Earth

resistance remains same over wide temperature variation range viz -

600 to + 60

0.

Features of Earth enhancement Chemical "LOHM" 

•  Absorbs and retains moisture for long time

•  Reduce soil resistivity

•  Dissipate fault current very fast

• 

Eliminate needs of salt and chemical around electrode•  Maintain compatibility of soil and rod contact

•  No need of maintenance for longer time

•  Earth resistance remains same for longer time even large temperature variation.

•  Resistivity of chemical is less than 0.1 ohm-m

3. 

Pit Cover:

o 

Generally used to cover the whole Earthing Pit.

o 

Made of High Class plastic (unaffected by water)

Accessories used with Earthing Electrodes are

•  Standard Ground Rod Clamps

•  High Strength Ground Rod Couplings•  Driving Studs

•  Rod to Tape Clamp•  B Bond

•  U Bolt Rod Clamp•  Brass Earth Clip

•  Domestic Rod Earth Clip Suitable for cables in the range 4-25mm2
