for such applications. The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre substations can be designed with GIS technology. The distinctive advantages of SF₆ Gas Insulated Switchgear are: compact‚ low weight‚ high reliability‚ safety against touch contact‚ low maintenance and long life. Extensive in-plant preassembly
