gis substation tools for Maintenance

GIS is characterised by high service reliability, low maintenance expenditure and long lifetimes. GIS technology requires more investment costs compared to air-insulated substations (AIS), however, due to its space saving features, this technology often offers the only solution where available space is limited.
