Power lines are power lines. With their help, electricity is supplied to buildings and other facilities. The laying of power lines is usually made by air with the help of appropriate supports. Since the durability of these supports depends on the service life of high-voltage lines, they are subject to increased requirements. Reliable corrosion protection is an effective way to extend their service life. the Hot-dip galvanizing of transmission towers can significantly increase the anti-corrosion properties of the metal. When galvanized parts are covered with a layer of zinc, which is not subject to corrosion. When processing steel with zinc, cathodic protection is formed, which will not allow corrosion even if the protective layer is broken.
In order to produce hot-dip galvanizing power line supports must be equipped with special equipment. First, you need a fairly large bath in which the pre-preparation and galvanizing itself. It is also necessary that the crane, by means of which the parts are immersed in the molten zinc and removed from it, could strictly withstand the specified speed. This speed affects the final characteristics of the part. If the rate of immersion is observed, the reaction of steel and zinc is achieved. And the extraction rate affects the thickness of the zinc layer.
