        Gas insulated metal-enclosed switchgear (hereinafter short as GIS) is created by the combination of standardized function modules such as circuit breakers, disconnectors and earthing switches, transformers, arresters, busbars, cable sealing ends, supplementary modules, etc. All the components are enclosed in the metal enclosure, which full filled with SF6 gas as arc extinction and insulating medium.
        GIS is one of the most important equipments in the line output and distribution system for control and protection, which has advantages for small size, space saving, easy installation, and not affected by the surroundings for its high availability. GIS can also assemble freely, maintain easily, and have low repair requirement, which is widely used in hydropower station and transformer station.
        Gas insulated switchgear ELH1 applies to the advanced international technology and experience in research and development, manufacture and test process. It has technology advanced, high availability and easy maintenance, etc.
        ELH1 type gas-insulated switchgear with rated voltage 126kV and short-circuit current 40kA, manufactured by Tianshui Changcheng Switchgear Factory, conforms to GB7674 standard- Gas Insulated Metal Enclosed Equipment above 72.5kV and relevant specification, which is suitable to use and install in outdoor or indoor condition.
