Why chose Cu-Cr for shield in vacuum interrupter?
Nov 08, 2017

        



 Shield is used to prevent the splashing of metal vapor in order to keep the insulation capability of vacuum interrupter. Stain steel and Cu-Cr are widely used for the raw materials of shield. Compared to stain steel, Cu-Cr has a great advantage of extinguishing the arc except for insulation, especially for TMF which has higher arc density on the edge of contacts.

At the customer's request, shields can be customered by special design. The main preparation method : Vacuum casting and Powder Metallurgy.
