Copper clad steel grounding conductor
Copper clad steel grounding conductor, was produced by cold rolling hot drawing technology overcomes the plating and the adhesion strength of the casing coated method exists some shortcomings, with copper layer thickness, low resistance, strong corrosion resistance, high strength, convenient installation, electrical connection performance is good wait for an advantage, it is widely used in power transmission and transformation and communications lines, power stations, buildings and grounding device of antenna, also can be used in the grounding system of electronic equipment such as computer, and can and meet ShanQi (lightning rod, wire) and downlead of lightning protection grounding device.
Because of the copper clad steel composite material has good conductivity, high mechanical strength, especially the outer cladding copper layer has good corrosion resistance, so has been widely used in the grounding device. Now our country stipulate grounding conductor can be used in relevant standards of copper clad steel composite materials. Copper clad steel composite material to replace steel grounding conductor or galvanized Angle steel, has been increasingly accepted by the design institute and engineering construction unit, adopt, recognition and popularity.

Characteristics and technical advantages:
1, unique manufacturing process: the production process of cold rolling hot weld between copper and steel metallurgy. Can be like a single metal drawing any drawing, not disconnect, become warped skin, cracking phenomenon.
2, superior anticorrosive: composite interface using high temperature welding, no residue, combined with the surface there will be no corrosion phenomenon; Surface copper layer thicker (average thickness greater than 0.4 mm) corrosion resistance is strong, long service life (more than 30 years), reduce the labor intensity.
3, better electrical properties: excellent electrical conductivity, surface copper materials to make its own resistance value is far lower than the conventional materials.
4, safe and reliable widely: this product is applicable to different soil moisture, temperature, PH value and under the condition of the resistivity changes ground construction.
5, safe and reliable connection: use a dedicated connection tube or a heat welding, joint is firm and good stability.
6, convenient installation, complete accessories, installation is convenient, can effectively improve the construction speed.
7, increase the depth of the grounding: special connection transmission way, 35 meters deep underground, low resistance requirements to meet the special occasions.
8, low construction cost: contrast traditionally use pure copper ground rod, zone, the method for construction cost greatly decreased.
The main technical parameters:
1, copper the thinnest thickness is 0.3 mm or more
2, tensile strength, n. 600 mm or more
3, straightness error of 1 mm or less
4, copper layer plasticity: grounding rods (line) bending 30 degrees, the Angle, both inside and outside edge no crack phenomenon.
5, copper layer: spent by adhesion test, in addition to the jaws clamp jaw occlusal apparent flake copper layer, combined with the rest of the copper steel does not appear good stripping phenomenon.
Scope of application:
Widely used in power plants, substation, transmission line tower, communication base stations, airports, railways, all kinds of high-rise buildings, microwave relay station, the network computer room, grounding, oil refinery, oil depots and other places to anti-static grounding, protective grounding, working, etc.
