Product Description
Middle cabinet, all known as metal armor in the case of a shift switch equipment. It is a high voltage distribution unit with a maximum operating voltage of 3.6 / 7.2 / 12kV and is an indoor distribution unit of a three-phase AC 50 Hz single bus segment system or a double bus segment system. It is used to receive and match the network electricity of 3.6-12kV, and to control, protect, monitor and measure the electric circuit. Medium type switchgear is mainly used for power plant, small and medium power generator, power substation of power system, power supply, power distribution of industrial and mining enterprises, and starting of large high voltage motor.
Zhongzhigui's full name is the Armoured Installed Switchgear, which moves the medium metal switch with a three-tier structure, with a bus and dashboard(isolated from each other), a circuit breaker room in the middle and a cable room in the lower. Because the circuit breaker is in the middle layer, so it is called the armor type to move the type of metal closed switch equipment, short for the cabinet.
