Electroshield Samara started production of column-type SF-6 circuit breakers of rated voltage 110 kV. Circuit breakers are designed for switching electrical circuits under normal and emergency conditions in three-phase AC networks.
Advantages of SF-6 circuit breaker VGT-SESH-110:
SF-6 circuit-breaker VGT-SESH-110 is used both for new construction in 110 kV complete transformer substations, and for replacing circuit breakers that have exhausted their life cycle, isolators, short-circuiting switches.
