The VEP - 12 series enclosed type high voltage vacuum circuit breaker, apply to the rated voltage 7.2 ~ 12 KV, three-phase ac power system frequency 50 HZ, widely used in power plants, substations, petrochemical, metallurgy, manufacturing, airports and village, etc., for the protection and control of electrical devices, especially suitable for the rated power flow frequent operation or open circuit of short circuit current place for many times, can be installed in open or stationary air insulated switchgear. Products in line with GB1984 "AC high voltage Circuit breaker", DL/T403 "12~40.5kV indoor AC high voltage circuit breaker order technical conditions" and IEC60694, IEC6227-100 and other relevant standards and requirements.

Vep-12KV series fixed seal type high voltage vacuum circuit breaker adopts advanced APG technology, and the vacuum arc interrupter and the leading circuit are directly fixed inside the epoxy resin pole to form a fixed seal insulation mode, which represents the highest level of design and manufacture of high voltage vacuum circuit breaker in the world.

Note: When the vacuum arcing chamber solid seal pole column of this model product is replaced by the installation method of ordinary insulation cylinder, the model is VS1-12.
