Our rich experience in development and manufacture of circuit breakers with SF6 gas as a media for insulation and extinction of arc has started since early 70-ies. Until today we have, on the basis of own research and development efforts within area of assembly technique of high and medium voltage, developed a few generations of SF6 breaker 38 kV – 420 kV for indoor and outdoor installations.
Our product scope includes:
- circuit breaker 72.5 kV -170 kV with motor-spring operating mechanism, SFEL type
- circuit breaker 72.5 kV - 420 kV with electro-pneumatic operating mechanism, SFE type and
- circuit breaker up to 38 kV with motor-spring operating mechanism, SPP, SPPE, SPPED types.
We have paid a lot of attention for development of medium voltage circuit breaker, up to 24 kV, where is used vacuum media for both insulation and extinction of arc.
The following products are within the scope:
- circuit breaker up to 24 kV, HGV type
- circuit breaker up to 24 kV, VPE type
