1. FZN25-12kv 11kv 10kv indoor type high voltage air load break switch with fuse
FZN25-12kv 11kv 10kv indoor type high voltage air load break switch with fuse is used in the ring network city distribution and industrial equipment of 12KV and three-phase AC 50Hz to cortrol load and short-circuit. Because the switch with fuse protecting transformer etc more reliably than circuit breaker. It is especialy suitable for ring network clouble radial distribution and package substation.
