******* Copper Earth Rod********************
** Introduction **
Copper bonded earth rod is mainly used in the grounding device. Due to its good conductivity, corrosion resistance, tensile strength, low prices, etc., Copper bonded earth rod can be widely used, and have been recognized by the United States Institute of Electrical and Electronics Engineering (IEEE) standard, BS standard and International Electrotechnical Commission (IEC) standards. In China, 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 earth 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 earth 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 earth 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 earth rod has conductivity of copper, and steel's large tensile strength (up to 580N/mm2) characteristics. In construction operations, earth 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.
**Technical Specification:
1) Thickness of the copper layer is more than 0.254mm(all can be done to your demand)
2) The core steel rod shall have a tensile strength of not less than 580Nm/mm2.
3) The steel core is low carbon steel, and the carbon content is about 0.15%.
4) The purity of the copper using as cladding shall be 99.9% pure copper.
5) The Earth Rod will be capable of being through 90 at a maximum radius if 100mm with no copper fracture and with no ill effect on the bond between the steel and the copper cladding.
6) Good in anticorrosion that usage-life is more than 50 years or more, constant low resistance and good plasticity which had the characteristics of copper as well as steel
