LW8-40.5kV SF6 Circuit Breaker
LW8-40.5 Outdoor HV SF6 circuit breaker is three-phase AC 50Hz outdoor high voltage electrical equipment for 35kV transmission and distribution system control and protection can also be used for opening and closing of contact breaker and capacitor bank of the occasion, and current transformer can be included for measurement and protection purposes. Circuit breaker equipped with CT14-type spring operating mechanism. Meet the national standard GB1984-89 "AC high voltage circuit breakers" and the International Electrotechnical Commission standards IEC56 publication, "High-voltage AC circuit breaker" requirements.
Features:
1. Breaking performance, arcing time is short, long electrical life at rated voltage continuously breaking 31.5kA 20 times without maintenance, not replacement of sulfur hexafluoride gas.
2. Insulation reliable pressure gauge when the zero-tolerance 40.5kV/10min;
3 mechanical reliability is high, closing ability, can often operate;
4 to open and close without capacitor current 400A renewed;
5.25, 50 km long cut empty without renewed;
6 simple structure, small size, long period without maintenance.
