C-GIS (Cubicle Gas-Insulated Switchgear) is a type of metal-enclosed switchgear that uses gas insulation. It is mainly used in medium and high voltage power systems up to and including 35kV. Its core features include modular design, compact structure, and high reliability. It is suitable for power plants, substations, industrial and mining enterprises, and urban rail transit.
