Sulfur hexafluoride ring main unit (SF₆ ring main unit) is a medium-voltage power distribution equipment that uses sulfur hexafluoride gas as an insulating and arc-extinguishing medium. It is an important equipment for power transmission, control and protection. Its main features are compact structure, small size, strong insulation performance, reliable operation, and the ability to realize the integrated packaging of multiple electrical functions such as load switches, circuit breakers, and disconnectors. SF₆ gas forms a fully insulated and fully sealed operating environment in a closed stainless steel gas box, which greatly improves the dustproof, waterproof and corrosion-resistant capabilities of the equipment. It is particularly suitable for harsh environments and occasions with high requirements for power supply reliability. In addition, with the development of smart grids, more and more sulfur hexafluoride ring main units have intelligent functions such as remote monitoring, self-diagnosis, and automatic reclosing, becoming one of the core equipment for building modern intelligent distribution systems. With the advancement of the green and low-carbon trend, SF₆-free or low SF₆ environmentally friendly products using environmentally friendly alternative gases have also been derived to reduce greenhouse gas emissions.
