"Copper-Aluminum Composite Grounding Block" for Rail Transit Grounding Conductive Copper-Aluminum Composite Grounding Seat
2024-04-30
Due to the different physical properties of the two metal materials of copper and aluminum, copper and aluminum cannot be directly used in the air, otherwise electrochemical corrosion will occur; the metal composite interface of the composite material reaches a metallurgical bonding state, and there is no medium in the middle, and electrochemical corrosion will not occur. Therefore, the copper-aluminum composite products produced by our Sanxie Metal have been successfully used on the grounding device of rail transit. The use of special grounding blocks for cloud rail, subway and high-speed rail has solved the problem of copper-aluminum connection between the car body and the electrical system, greatly improving the safe operation capability of rail transit, and the special surface treatment technology can ensure the stable operation of the products during long-term use.
The function of the copper-aluminum composite grounding block: The copper-aluminum composite grounding block is a conductive grounding device used on the aluminum alloy car body of the light rail subway. The basic structure of this grounding device is: through the composite connection of copper and aluminum bimetals, The aluminum alloy surface is raised for connection; the obvious problems of this grounding device are: copper and aluminum are difficult to weld, the device is poor in firmness, and is susceptible to corrosion and deformation, the copper block cannot be replaced after being used for too long, and the practicability is poor. In order to solve the above problems, we have provided a copper-aluminum high-strength composite grounding block with good conductive effect, good composite effect, and very convenient welding and installation.
Ningbo, Zhejiang: East-West Industrial Collaboration Hatches "Golden Phoenix"
Just after the Spring Festival, in the heavy Industrial Park in Xingren Baling Town, Guizhou, as one of the industrial cooperation projects in the Yangtze River Delta region and the western region, a new production line built by a group in Ningbo has attracted much attention. "This production line will produce a new product called'copper-aluminum eutectic plat', which will be independently developed by our team for more than two years." Xu Yinchang, the person in charge of the enterprise, introduced.
