LW30-252 High Voltage AC SF6 Ceramic Pole Circuit Breaker

The LW30-252 high voltage AC SF₆ ceramic pole circuit breaker is an outdoor high-voltage switching device for three-phase AC 50Hz, suitable for the control and protection of 252kV power transmission and distribution systems, and can also be used as a tie circuit breaker. This type of circuit breaker can be equipped with a CTY-10 hydraulic spring mechanism to achieve three-phase mechanical linkage, or with an improved CT26 spring mechanism for three-phase split-box operation. It fully complies with GB1984-2003 "AC High Voltage Circuit Breakers" and meets the requirements of the International Electrotechnical Commission standard IEC62271-100:2001 "High-voltage switchgear and controlgear - Part 100: High-voltage alternating-current circuit breakers".
