CONSTRUCTION MANUAL FOR GRID SUB-STATIONS. Gas-Insulated Substation (GIS) installations shall generally be preferred to conventional AIS as a techno-economic solution for location where space is a major constraint and also for seismic prone areas. However, techno-economic analysis shall be done to determine the preference for each GIS installation.

Jul 01, 2020One of the most promising insulation materials is aerogel. This newly developed insulation type has thermal resistance (R-value) of approximately 1.75 m 2 K/W or 10 h ft 2 F/BTU (2–2.5 times the R-value of mineral wool insulation) and is resistant against fire in addition to being water repellant. One of its appealing features is that it can come as semi-transparent forms (See Fig.
