XGN66-12 High Voltage Ring Main Unit

XGN66-12 (Z) box type fixed AC metal enclosed switchgear (hereinafter referred to as switchgear) is a new generation of high-voltage electrical equipment complete set product of our company, which meets the requirements of the national standard GB3906 “-35kV AC enclosed switchgear” and the technical conditions for ordering indoor AC high-voltage switchgear DLT404 of the Ministry of Electric Power, as well as the international standard IEC60298 “Requirements for AC metal enclosed switchgear and control equipment above 1kV and below 52kV”.

This product has absorbed advanced technology from abroad. It is small in size, only 50% of the volume of ordinary switchgear. The circuit breaker has high reliability, good performance, and the “five prevention” interlocking mechanism is reliable and simple. The switchgear is an indoor complete set of equipment with 3.6, 7.2, 12kV three-phase AC 50Hz single busbar segmented, used for receiving and distributing electrical energy. And it has functions such as controlling, protecting, and monitoring circuits, and can be used in various types of power plants, substations, industrial and mining enterprises, high-rise buildings, etc. It can also be combined with ring main units and applied in switch stations.
