Medium voltage outdoor voltage transformer is an indispensable key measuring device in the power system. It is mainly used to realize accurate transformation and electrical isolation of medium voltage grid voltage in outdoor environment.

Drop-out fuses are an important protection device widely used in power systems. Their main function is to quickly cut off the current when the circuit is overloaded or short-circuited, thereby protecting the safety of electrical equipment and lines.

Power transformers are mainly used in power transmission systems, working at high voltage levels, such as 110kV, 220kV, etc., with large power, usually 10000KVA and above. Distribution transformers are mainly used in power distribution systems, working at medium and low voltage levels, such as 10kV and below, with small power, generally below 2500KVA.
