An Overview on GIS (Gas Insulated Substation) Engineering

GIS substations use gaz sf6 gas that reduces the distance needed between active and non-active switchgear parts resulting in smaller overall space requirements (ideal for congested city areas). GIS substations also offer lower operating and maintenance costs; and are less sensitive to pollution, salt, sand and large amounts of snow.Get price
