The HXGN-12 switchgear is suitable for distribution systems in industrial and mining enterprises, residential communities, high-rise buildings, and school parks. It serves as an indoor three-phase AC power supply unit and terminal distribution equipment for 12kV, 50Hz ring network applications. It can switch on or off the rated load current and the no-load current of transformers, as well as disconnect or connect overhead lines, cable lines, or capacitive currents over a certain distance. The load switch-fuse combination cabinet can interrupt the rated short-circuit current in a single operation.
Introduction of High and Low Voltage Switchgear HXGN-12
Some structural features of High and Low Voltage Switchgear HXGN-12:
The HXGN-12 High and Low Voltage Switchgear is constructed from 8MF type steel, which is partially welded and then bolted together. It primarily houses the FZN21-12 type two-position vacuum load switch, which is used in conjunction with a fuse equipped with an impactor to form a combined electrical device. This type of switchgear can be flexibly equipped with current transformers (CT), potential transformers (PT), and ZnO surge arresters. Its base is fitted with a removable access cover for easy cable entry, and for overhead cable entry, a busbar channel can be added according to user requirements.
