The LW-252/4000-50 self-energy AC high-voltage sulfur hexafluoride circuit breaker is an outdoor product suitable for altitudes not exceeding 2000 meters and ambient temperatures not lower than -In an AC 50Hz power grid with a maximum voltage of 252kV at 30 ºC and a pollution level not higher than Level IV, it is used to cut off rated current, fault current, or convert lines to achieve The control and protection of the power system can also be used as a tie breaker. This product uses SF6 gas as the arc extinguishing and insulation medium, adopts the most advanced self-energy arc extinguishing technology in the world, and is equipped with a new type of spring operating mechanism, which has an electrical lifespan Long, low operating power, low noise, and high reliability, with simple structure, small volume, and long maintenance cycle. Currently, power equipment tends to be oil-free and high-capacity In the process, it can completely replace imported products of the same type.
