The VTV (new VD4 type VCB) primary distribution circuit-breakers with integrated sensors and protection control unit completely redefine the process of constructing medium voltage switchgear.
VTV series vacuum circuit breaker is newly developed by ourselves. It embodies our ideas: compact, intelligent, environmental-friendly, energy-efficient and maitenance-free.
VTV series have wider application,such as power grid, power plant, petrochemical engineering, coal industry, metallurgy, railway and airport transportation system.
Modularized operating mechanism is another feature of VTV. The operating mechanism is located in the chassis . The opening module and closing module are integrated, independent of other parts in the mechanism. So it is convenient to maintain and rapid to replace.
Its mechanical life can up to 60000 operations. It can be added with intelligent unit to be an intelligent vacuum circuit breaker.
