Gas Insulated Switchgear is a medium to high voltage power equipment that uses insulating gases such as sulfur hexafluoride (SF6) as arc extinguishing and insulation media. It seals core components such as circuit breakers, isolating switches, and grounding switches in a metal casing, and has significant advantages such as compact structure, occupying only one-third to one-fifth of the traditional equipment, high reliability, and a maintenance free cycle of more than 20 years; Its fully enclosed design can effectively resist harsh environments such as humidity, dust, salt spray, etc. It has excellent arc extinguishing performance and can quickly cut off short-circuit current, ensuring the safe and stable operation of the power system. We rely on advanced gas sealing and intelligent monitoring technology, strict ISO quality control system, and a global after-sales network to provide customers with one-stop services from customized solution design, professional installation and commissioning to full life cycle maintenance, 24-hour emergency response, and help build an efficient, intelligent, and environmentally friendly modern power grid system.
