Copper Bonded Steel Electrode

Approx Price: Rs 3,000 / Piece(s) 

Gmax make Copper Bonded Steel Electrode Rod

The earth electrode shall be made of high tensile low carbon steel circular rods, molecularly bonded with copper on outer surface to meet the requirements of Underwriters Laboratories (UL) 467-2007 or latest. Such copper bonded steel cored rod is preferred due to its overall combination of strength, corrosion resistance, low resistance path to earth and cost effectiveness.

The earth electrode shall be UL listed and of minimum 17.0mm diameter and minimum 3.0mtrs. long.

The minimum copper bonding thickness shall be of 250 microns.

Marking: UL marking, Manufacturer’s name or trade name, length, diameter, catalogue number must be punched on every earth electrode.

Earth electrode can be visually inspected, checked for dimensions and thickness of copper coating using micron gauge. The suppliler shall arrange for such inspection at the time of supply, if so desired.

Gmax Earth Enhancement Material

Approx Price: Rs 1,200 / 25 kg 
Earth Enhancement material

Earth enhancement material is a superior conductive material that improves earthing effectiveness, especially in areas of poor conductivity (rocky ground, areas of moisture variation, sandy soils etc.). It improves conductivity of the earth electrode and ground contact area. It shall have following characteristics-
- Shall mainly consist of Graphite and Portland cement. Bentonite content shall be negligible.
- Shall have high conductivity, improves earth’s absorbing power and humidity retention capability.
- Shall be non-corrosive in nature having low water solubility but highly hygroscopic.
- Shall have resistivity of less than 0.2 ohms-meter. Resistivity shall be tested by making a 20cm. cube of the material and checking resistance of the cube at the ends. The supplier shall arrange for such testing at the time of supply, if so desired. Necessary certificate from National/ International lab for the resistivity shall also be submitted.
- Shall be suitable for installation in dry form or in a slurry form.
- Shall not depend on the continuous presence of water to maintain its conductivity.
- Shall be permanent & maintenance free and in its “set form”, maintains constant earth resistance with time.
- Shall be thermally stable between -100 C to +600 C ambient temperatures.
- Shall not dissolve, decompose or leach out with time.
- Shall not require periodic charging treatment nor replacement and maintenance.
- Shall be suitable for any kind of electrode and all kinds of soils of different resistivity.
- Shall not pollute the soil or local water table and meets environmental friendly requirements for landfill.
- Shall not be explosive.
- Shall not cause burns, irritation to eye, skin etc.

Gmax Exothermic Welding Material

Approx Price: Rs 4,000 / Piece 
Gmax The Terra Weld Exothermic Welding System provides the ultimate in permanent molecular bonding. The process of exothermic welding, in which no outside source of heat or power is required, is the universally preferred method of making electrical connections of copper-to-copper or copper-to-steel. Lightning protection and grounding systems require connections that maintain current carrying capacity exceeding that of the conductors used in the system. Terra Weld connections provide higher fusing capacity than the conductors to which they are bonded. System resistance, impedance, and ampacity relate directly to functionality, safety, and regulatory compliance. Terra Weld meets these challenges and delivers assurance.
