Introduction
The HXGN-12 AC metal-enclosed switchgear (hereinafter referred to as the ring main unit) is an AC high-voltage complete equipment device with a rated voltage of 12kV and a rated frequency of 50Hz. It is mainly used in three-phase AC ring main units, terminal distribution networks, and industrial power-consuming equipment for the functions of receiving, distributing electrical energy, and protection. It is also suitable for installation in box-type substations.
It meets GB3906 3.6-40.5 AC Metal-Enclosed Switchgear and Control Equipment and meets the requirements of the international standard IEC298 AC Metal-Enclosed Switchgear and Control Equipment. It also features the “five-proof” interlocking function.
