Product description

JN22-24/31.5 Indoor 50HZ HV Moter Drive 24KV Switchgear High Voltage Earthing Switch 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 12~24KV 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.

Application

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.

Operation conditions

1,The altitude does not exceed 1000m.
2,The ambient air temperatrue : Max:+40oC. Min:-10oC.
3,The relatire humidity of air Daily average ≤95% . Monthly average ≤90% (temperature:25oC)
4,The ambient air should not be obviously polluted by corrosivity and the flammability gas.Etc.
5,The working situation without frequent violent.
