145kV GIS
Product Characteristics
ZF10-145 Gas Insulated Metal-Enclosed Switchgear (referred to as GIS) is a complete set of switchgear which combines the circuit breaker, three-position switch, fast earthing switch, current transformer, voltage transformer, lightning arrester, bus bar, outgoing and incoming line bushings or cable termination and encloses them in an earthed metal enclosure. It is filled with SF6 gas as insulating and arc-extinguishing medium. It’s suitable for three-phase AC 50Hz and 60Hz power system under voltage of 72.5kV to 145kV.
