General Introduction of 550kV high voltage SF6 breaker

This mechanism is suitable for 550kV high voltage SF6 circuit breaker, and its performance is meet:

IEC 62271-2008 《 Alternating-current circuit-breakers》

IEC 62271-2007 《High-voltage switchgear and controlgear》

IEC60056-1987 《High-voltage alternating-current circuit-breakers》


The mechanism has two charge modes: electric and manual.The opening and closing operation has remote control, local operation, electric operation and manual operation


With the aid of special tools, the mechanism can be opening and closing slowly.
