2 The TGOOD 145kV Compact GIS Substation reduces construction times to between 3 and 6 months and uses only 20% of the space required by a traditional substation PRODUCT CONCEPT TGOOD engineers set out to create a better urban substation, patenting 38 features that combine to create a next generation solution for modern cities and industrial sites around the globe. Increased urbanization and growing demand for electricity necessitates new substation construction in congested built-up areas. Traditional substations create fears of noise and radiation and may be prone to vandalism. Traditional substations require a footprint of up to 3300m 2 and require at least 18 months to construct, straining scarce land resources and subjecting the area to expensive and unsightly construction projects kV Compact GIS Substation

3 KEY BENEFITS SPEED Compared to traditional substations, construction times are reduced to between 3 and 6 months and commissioning times are reduced to just one month or less. SPACE SAVINGS Compact substations reduce the land space required to as little as 420m 2, conserving valuable land in congested urban and industrial areas. SAFETY AND APPEARANCE Acoustic and electromagnetic shielding reduce noise and radiation for safe and silent operation (below 40dB). E-House enclosures are safe to touch and provide exceptional protection against vandalism. Custom paint work helps the station blend in with surroundings kV Compact GIS Substation 3
