10kv indoor high voltage load switch FLN36-12/630A hexafluorosulfur load switch SF6 load switch
The load switch is a kind of switching device between the circuit breaker and the isolating switch. It has a simple arc extinguishing device that can cut off the rated load current and a certain overload current.
The load switch is mainly used to break and close the load current. The load switch can also be used in conjunction with a high-voltage fuse instead of a circuit breaker. Because the load switch is convenient and reasonable to use, the load switch is used in the 10kV distribution network system. Reasonable selection of load switches in the design is of great significance to ensure the safe and reliable operation of the power grid.
