Product Detail
Used for rated voltage 12kv below power network systems for remote making and breaking and frequent starting and control of AC motors
Used for rated voltage 12kv below power network systems for remote making and breaking and frequent starting and control of AC motors, transformers and capacitor banks and other occasions.
CKG4-7.2kv/800A (vacuum switch) high-voltage vacuum contactor 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 7.2kV or under 7.2kV, 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.
