High performance VBM8 VBM***0.5 indoor high voltage vacuum circuit breaker
1.vacuum circuit breaker with IEC standard
2.high voltage vcb
3.OEM service
4.ceramic metarial
VBM8/VBM***0.5 indoor high voltage vacuum circuit breaker is a
domestic leading product new product research and developed by
our company. The main characteristic of dominant electric circuit
is fixed in enclosed three-poles isolate cylinder. The brand new
kind of operation mechanism is in front of the circuit, structure
is simple and reliable. This kind of VCB is widely applied to
electric factory, power grid, metallurgy, petrify, city
infrastructure project such as air port, underground. It can
protect and control cable, overhead line, transform and
electromotor, generator and capacitor bank.
It has perfect mechanical and electric interlock device, extremely reliability and service life, ensure the safety of operator and the instrument. Each mechanical data are all sticks to GB***4, GB/T****2 and electric industrial standard DL**3.IEC********0, IEC*6 and other formulation of main industrial countries.
