Complaint
Xgn66-12 box type fixed AC metal-enclosed switchgear (hereinafter referred to as simple switchgear) is a new generation of a complete set of high-voltage electrical appliances designed and developed by our factory, which meets the requirements of the national standard GB3906 "3 ~ 35kV AC metal-enclosed switchgear" and the Ministry of electric power DL / t404 "technical conditions for ordering indoor AC high-voltage switchgear", It also meets the requirements of the international standard iec60298 AC metal-enclosed switchgear and control equipment above 1kV and below 25kV.
This product has absorbed the advanced technology of foreign countries and is designed and developed for the problems of high accident rates and a large volume of existing similar switchgear in China. It has the advantages of small cabinet volume (only 50% of the volume of an ordinary switch cabinet), good circuit breaker performance, high reliability, and a reliable and simple "five prevention" interlocking mechanism.
