Overview
HXGN66-12 fixed metal-enclosed switchgear (hereinafter referred to as switchgear) is a complete set of high-voltage electrical equipment newly launched by our company, which meets the requirements of national standard GB/t3906《3.6 kV-40.5 kV AC metal-enclosed switchgear and control equipment》 DLT404《Technical conditions for ordering indoor AC high-voltage switchgear》, and also meets the international standard IEC 60298 《AC metal-enclosed switchgear above 1 kV and below 52kV》. This product has absorbed foreign standard technology, and its volume is small, which is only 50% of the volume of ordinary switchgear; Circuit breaker has high reliability and good performance; The "Five Prevention" interlocking mechanism is reliable and simple. Switchgear is a complete set of indoor devices with 3.6, 7.2 and 12kV three-phase alternating current and 50Hz single bus section, which is used for receiving and distributing electric energy. It has the functions of controlling, protecting and monitoring circuits, and can be used in various power plants, substations, industrial and mining enterprises, high-rise buildings and other places, and can also be combined with ring network cabinets to be used in opening and closing stations.
