Product Overview
The XGN66-12 fixed enclosed switchgear (hereinafter referred to as the switchgear) is our company's new generation of high-voltage electrical equipment set, in compliance with the national standard GB3906 "AC Metal-Enclosed Switchgear for -35KV" and the electrical department's DLT404 "Technical Conditions for Ordering Indoor AC High-Voltage Switchgear." It also meets the international standard IEC298 "Requirements for AC Metal-Enclosed Switchgear and Control Equipment above 1kV and below 52kV." This product absorbs foreign technology, featuring a small size, just 50% of the volume of a regular switchgear; the circuit breaker boasts high reliability, good performance, and advantages such as reliable and simple "five prevention" interlock mechanisms. The switchgear is an indoor complete set for 3.6, 7.2, and 12kV three-phase AC 50Hz single busbar sectioning, used for receiving and distributing electrical energy. It also has functions for circuit control, protection, and monitoring, and can be used in various types of power plants, substation, industrial and mining enterprises, high-rise buildings, and can also be combined with ring main cabinets for application in switchyards.
