◆ Product overview

HXGN15A-12 (F.R) box type fixed AC metal enclosed ring network switchgear (referred to as "ring network cabinet" for short) is a new type of high-voltage switchgear produced for the reconstruction and construction of urban power grids. It is also used for breaking load current, short circuit current and closing short circuit current in the power supply system, and is applicable to the power distribution system of AC 3-10KV and 50Hz. It is widely used in urban power grid construction and transformation projects, industrial and mining industries, high-rise buildings and public facilities, etc. As the ring network power supply unit and terminal equipment, it plays the role of power distribution, control and protection of electrical equipment, and can also be installed in pre installed substations. This ring main unit is equipped with vacuum load switch and spring operating mechanism, which can be operated manually or electrically. The grounding switch and disconnector are equipped with a manual operating mechanism. This ring network cabinet has strong integrity, small size, no risk of combustion and explosion, and has a reliable "five prevention" function.
This product cabinet complies with the relevant provisions of GB3906 3.6-40.5KV AC Metal Enclosed Switchgear and Control Equipment and GBI6926 AC High Voltage Load Switch Fuse Combiner.
