General:
VB-12 Indoor high voltage vacuum circuit breaker independently
developed by our company is the leading domestic level of a new
generation of 12kV vacuum circuit breaker, Its main feature is
that the main circuit is installed in the full sealed three-phase
insulating cylinder the operation mechanism and the main circuit
was of before and after layout The operating mechanism is new-
type spring one, which is independently researched and developed
by my company, has the advantages of simple structure, reliable
action, and manufacturing experience for launching tens of
thousands of the products, used and referenced by a number of
domestic high-end vacuum circuit breaker manufacturers.
