It is designed and developed by our own company by bringing
ininternational advanced technology, considering our own
country’sspecificpower supply. It performances meet IEC420 《AC H.V
LoadSwitch with Fuse》(1990 Edition) and GB3804 《3-63KV AC
H.V.LoadSwitch》after strict test and long-time operating. compared
toproduct of the kind in the foreign country , its
technicalparameter has reached the international level with the
features ofsmall volume and light weight. Can be used in package
substationand ring network cebin . It is used widely in 12KV
distributionnetwork to protect the equipment againet working
without phase.
The sucess of the product fills the domestic gap ,with
functionsof switch、isolating and earthing.
It is used in the network of 50Hz rated voltage 6-12KV
forbreaking load、over-load and short-circuit current , It is
equippedwith CS6-Ⅰ type handle operating mechanism. It is for the
CS□handle mechanism.
