CKG4 12kV High-voltage Vacuum Contactor

CKG4 series high-voltage vacuum contactor (vacuum switch)consist of separable insulator bracket and metal frame. It has advantage of firm structure, high reliability, contact from the large open, better breaking capacity and smaller bounce at contact closing and opening. It is suitable for the distribution system of metallurgy, mine, petro-chemistry and building, to control the equipments used eletricity such as high-voltage motor of 12kV or under 12kV, transformer and capacitive loading etc. Especially suitable for frequent operation domain. Because of its small volume, light weight and packaged design of upper and lower arrangement, prevalent in the world. It is convenient to use and maintain, and is easy to form the complete equipment of F-C loop.
