Brief Instruction of Copper Clad Steel Stranded Wire The copper-clad strand wire is shaped like a cable, which is made of a plurality of copper-clad single wires. Because of its multi-stranded properties, the electrical conductivity and tensile strength are relatively good, and the product can be customized to enhance the elongation rate by multiple heat treatment in the production process, which has increased the strength and toughness of the steel compared with the pure copper strand. Moreover, the good electrical conductivity and corrosion resistance of the copper material are maintained due to the principle of the skin effect. Therefore, it is very popular in many fields of lightning protection and grounding, especially in power plants, substations, high-speed rail, subways, electrified railways, large-scale chemical plants, mechanical plants, communication base stations, transportation, computer rooms, highways and military bases.

Points for Attention in Design of Tank Grounding System in Gas Station: 1. Oil tanks should be lightning-proof grounding, and grounding points should not be less than two. 2. The buried oil tank should be electrically connected with the process pipeline exposed to the ground and it should be grounded. 3. The information system of gas station should be equipped with armoured cable or wire through steel pipe. Both ends of the metal skin of the distribution cable and the protective steel pipe should be grounded. 4. The joint grounding device of anti-static electricity and Anti-induction lightning should be installed at the beginning, end and branch of oil pipeline laid on the ground or pipe trench, and its grounding resistance should not be greater than 30 Ω. 5. Anti-static grounding device for unloading of petrol tanker should be installed in unloading site of petrol tanker station, and electrostatic grounding instrument should be installed to detect cross-connection and monitor the status of grounding device.
