It is designed and developed by our own company by bringing in international advanced technology, considering our own country's specificpower supply. It performances meet IEC420 (1990 Edition) and GB3804 <3-63KV AC H. V. Load Switch>after strict test and long-time operating. Compared to product of the kind in the foreign country, its technical parameter has reached the international level with the features of small volume and light weight. Can be used in package substation and ring network cebin. It is used widely in 12KV distribution network to protect the equipment againet working without phase.
The sucess of the product fills the domestic gap, with functions of switch\isolating and earthing.
Use
It is used in the network of 50Hz rated voltage 6-12KV for breaking load\over-load and short-circuit current, It is equipped with CS6-I type handle operating mechanism. It is for the CS handle mechanism.
