What is a prefabricated substation?
“A prefabricated substation, also known as a compact substation or package substation, is a fully assembled electrical substation built inside a weatherproof enclosure at the factory. It integrates transformers, switchgear, metering, and auxiliary systems into a single unit, reducing on-site construction time by up to 60%.”
View in the company profileWhat is the difference between a prefabricated substation and a traditional brick-built substation?
“Prefabricated substations are factory-built and delivered as complete units, while traditional substations are constructed on-site with bricks and concrete.”
View in the company profileWhat is an E-House (Electrical House)?
“An E-House is a walk-in, modular enclosure housing MV switchgear, LV switchgear, transformers, control systems, and auxiliary equipment. Unlike compact substations, E-Houses are large enough for personnel to enter for maintenance — typically 3m × 2.5m up to 18m × 4m.”
