VS1E - 12 kv indoor enclosed type column 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 the GB1984 "AC high voltage circuit breaker", DL/T403 "12~40.5KV indoor AC high voltage circuit breaker ordering technical conditions"
And IEC60694, IEC6227-100 and other related standards.
VS1E-12KV indoor sealed pole column high voltage vacuum circuit breaker adopts advanced APG process, the vacuum arc extinguishing chamber and the main circuit are directly sealed in the epoxy resin pole column to form a sealed insulation mode, representing the world's highest level of high voltage vacuum circuit breaker design and manufacturing.
Note: when the installation mode of this product is replaced by ordinary insulated cylinder, the type of this product is VS1-12.
