Conventional Outdoor Substations (AIS)
Conventional outdoor substations can be designed to suit a client’s particular requirements. Individual items of equipment are dependent on the substation’s voltage level, busbar scheme and number of feeders and air-insulated substations require a relatively large area of land which needs to be fenced.
Gas Insulated Indoor Substations (GIS)
Gas insulated substations generally are used in space constrained areas. Because of the compactness of the equipment which only requires a small area of land and minimal civil work resulting in substantial savings and makes GIS compatible with AIS at higher voltages.
Cellular Type Indoor Substations (AICS)
Innovative design and development of specialised equipment make air-insulated cellular indoor substation designs viable through the use of local outdoor-type equipment within a building. More than 15 cellular indoor substations have been designed.
