The copper clad steel grounding rod is developed on the basis of foreign technology and produced by special electroplating technology. It has the characteristics of thick copper layer (more than 0.25 millimeters), low resistance, strong corrosion resistance, high strength, easy installation, good electrical connection, good adhesion, no stripping (rolling thread) and so on. Its advantages are large tensile strength (tall 600 Newton / square millimeter), strong corrosion resistance (which can guarantee the service life of more than 30 years), with constant low resistance and good plasticity, both with copper and steel properties. The series of products produced in the electroplating process have overcome the defects of the poor bonding force in the casing coating method, and can be widely used in the grounding devices for transmission and transformation and communication lines, power stations, buildings and antennas. It can also be used for grounding systems of electronic equipment such as computers, and can be used with flash devices (lightning arresters, lightning arresters) and downline groups. Lightning protection grounding device. Copper clad steel grounding rod technical features: 1, the manufacturing process is unique: the most advanced electroplating process production process, bending after 180 degrees does not appear disjointed, warping, cracking.
1. The composite interface is welded at high temperature without residue and no corrosion will occur on the joint surface.
2, the surface copper layer is thicker (average thickness is greater than 0.25mm), corrosion resistance is strong, long service life (greater than 30 years), reduce maintenance labor strong.
3, electrical performance is better: the excellent conductivity of surface copper material makes its own resistance far lower than conventional materials.
4. Wide practicality: the product is suitable for grounding construction under different soil humidity, temperature, pH and resistivity.
5, the connection is safe and reliable: the use of special connecting pipe or hot melt welding, the joints are firm and stable.
6, installation is convenient and fast: complete fittings and convenient installation, can effectively improve the speed of construction.
7, improve the grounding depth: special connection drive mode, can go deep underground 35 meters, to meet the special occasions low resistance requirements.
8, the construction cost is low: compared with the traditional construction method of pure copper grounding rod and grounding zone, the cost is greatly reduced.
