Product Introduction
General
SF6 ring main unit is an air-insulated or gas-insulated medium-voltage electrical combination equipment that can be combined into multiple circuits at will, with switching, communication, and protection of the power system, with load switches as the core component. Its main circuit core component is composed of an SF6 load switch or additional circuit breaker and other primary auxiliary electrical appliances.
SF6 ring network cabinets can be divided into expandable and non-expandable types according to the combination method, and can be divided into co-box type (also known as gas-filled cabinet or SF6 fully insulated cabinet) according to different manufacturing processes
