** Introduction **

Copper bonded ground rod is mainly used in the grounding device. Due to its good conductivity, corrosion resistance, high tensile strength, low prices, etc., Copper bonded ground rod has a very wide range of applications, and have been recognized by the United States Institute of Electrical and Electronics Engineering (IEEE) standard, BS standard and International Electrotechnical Commission (IEC) standards. We have obtained the UL and CE certification. In China, our products have been recognized in China Sinopec, China National Petroleum, the national electricity company, and gradually be widely used. 

**Features **

1, the manufacturing process:

Copper bonded ground rod is cast through an electrolytic process, to 99.9% copper molecules evenly covering the steel core. It is very uniform copper layer and the thickness of 0.254mm or more. Products have conductive properties of copper and the tensile strength of steel. Since the copper layer and the steel material is a binding molecule, the copper layer is not easily peeled off, and will not crack when bent in operation.

2, good conductivity

Since the Copper bonded ground rod of the outer copper layer of 99.9% purity electrolytic copper, having a thickness of 0.254mm or more, the conductivity has been tested more than 40%, when the transmission frequency is greater than 1.67MHz, which is fully equivalent to the conductive properties of solid copper.

3, strong corrosion resistance:

The surface of the ground rod is 99.9% pure electrolytic copper. Combined with its copper and steel are molecules overcome their electrochemical corrosion, buried in the soil and thus has a strong resistance to corrosion, the service life of over 30 years.

4, tensile strength:

Copper bonded ground rod has conductivity of copper, and steel’s large tensile strength (up to 580N/mm2) characteristics. In construction operations, ground rods can be easily driven into depth of up to 20m or more under the ground. That will reduce a lot of trouble during construction and installation costs. 

**Applications**

The product can be widely used in the communications industry, power systems, building systems, military installations, railway systems, broadcasting systems and other equipment industries, the AC and DC work, safely protected, especially suitable for harsh surface environment, corrosion resistance requirements to ground engineering, its market prospect is very broad.
