High Voltage Gas Insulated Switchgear (HV GIS) Solution for Singapore
Ⅰ. Project BackgroundAs a city-state with the world's highest population density (7,615 people/km²), Singapore faces growing electricity demand (3.5% annual growth) amid extreme land scarcity (total area: 728 km²). Traditional air-insulated switchgear (AIS) struggles to meet the compact requirements of urban substations due to its large footprint and high maintenance costs. The High Voltage Gas Insulated Switchgear (HV GIS) emerges as the optimal solution given Singapore's equatoria
