Advantages and characteristics of "aluminum-clad steel grounding block" and "aluminum-clad iron grounding block" for rail transit
2024-04-30
The aluminum-clad steel grounding block used in the rail transit industry is a composite grounding block composed of aluminum plate and steel core, in which the aluminum plate covers the surface of the steel core to form an "aluminum-clad steel" structure. The advantage of this kind of grounding block is that the aluminum plate can prevent the corrosion of the steel core, and the conductivity of the aluminum plate is better, which can improve the grounding efficiency. In addition, due to the coverage of the aluminum plate, the grounding block is not easy to rust and be affected by the external environment, and has a long service life.
The aluminum-clad iron grounding block is also a composite grounding block composed of an aluminum plate and an iron core, wherein the aluminum plate covers the surface of the iron core. Compared with the aluminum-clad steel grounding block, the material of the aluminum-clad iron grounding block is different, so its electrical conductivity and corrosion resistance are also different. Because the electrical conductivity of iron is worse than that of steel, the electrical conductivity of aluminum-clad iron grounding block is relatively poor, it is easy to rust and be affected by the environment, and its service life is short.
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.
