Copper plated flat steel is made of electrolytic copper with a purity of more than 99.9% plated on low carbon steel by world-class plating technology. The thickness of each point of the copper plating layer is more than 0.254mm. Specific applications: it is used for equipment grounding downlead, grounding grid horizontal grounding conductor, cable trench and tower horizontal grounding conductor. The wiring is neat and convenient.

Compared with other horizontal grounding conductors, copper-plated flat steel has a huge advantage: it is cheap. Although the unit price of copper-plated flat steel is higher than that of galvanized steel, its current conduction capacity and service life are stronger than that of galvanized steel. Because the current conduction capacity of copper-plated flat steel is higher than that of galvanized steel, in order to achieve the same drainage capacity and grounding resistance in the same grounding project, the use of copper-plated flat steel is less than that of galvanized steel. Through comprehensive comparison, the cost of copper-plated flat steel in the same grounding project is equivalent to that of steel grounding system. From a long-term comparison, the service life of the grounding system using copper-plated flat steel is as long as 40 years, while the longest service life of the grounding system using galvanized steel is only 15 years. The grounding system using galvanized steel needs to be excavated, maintained and reconstructed every few years. The transformation of grounding system is more expensive and time-consuming than the construction of a new grounding system. In the long run, the cost of copper-plated flat steel is lower than that of galvanized steel. Excellent corrosion resistance, service life up to 40 years.

The corrosion resistance of copper for installation of galvanized flat steel is more than ten times that of steel, and copper plating is more than three times that of zinc plating. The corrosion resistance of copper plated steel is close to that of pure copper, and oxide (Copper Green Cu (OH) 2) with strong adhesion will be produced on the surface of copper, which has a good protective effect on the internal materials and blocks the formation of further corrosion Copper plated steel is widely used in grounding systems in European and American countries. The quality certification standard for this grounding material is ul467. Chapter 9 on page 11 of this standard clearly stipulates that the thickness of copper plated material of grounding rod must be greater than 0.25mm, and the copper plated material of copper plated stranded wire and copper plated flat steel greater than 0.070mm can be used as the grounding grid to ensure 40 years of maintenance free grounding grid. Strong current conduction ability. At 20? C, the resistivity of copper is 17.24 × 10-6 (Ω? Mm), the resistivity of steel is 138 × 10-6（Ω?mm）。 Assuming the conductivity of copper as the reference value 1 (i.e., 100%), the conductivity of angle steel and galvanized round steel is only 8.6%, the conductivity of copper-plated steel is more than 20%, and the conductivity of copper-plated steel strand is 30%. Under the action of lightning current and other high-frequency currents, copper-plated steel will produce skin effect, and its conductivity is close to that of pure copper and far higher than that of steel grounding body. In addition, the magnetic permeability of copper relative to vacuum is 1, and that of steel is 636 times. When passing lightning current or fault current, the impedance of copper conductor is much smaller than that of steel grounding body, so the probability of side strike caused by the rise of ground potential caused by impedance will be greatly reduced.

Copper plated flat steel is used as the down lead of equipment grounding, the horizontal grounding conductor of grounding grid, and the horizontal grounding conductor of cable trench and tower. There are generally three types of copper, copper plated flat steel and galvanized flat steel. Copper has the best drainage effect and corrosion resistance, and is the most suitable for equipment grounding downlead, grounding grid horizontal grounding conductor, cable trench and tower horizontal grounding conductor. But the price of copper is very high, and it will be stolen by thieves. Galvanized flat steel is the most widely used horizontal grounding conductor, but its drainage effect and corrosion resistance are not ideal.
