Prefabricated Substation Overview

Prefabricated Substation is configured for a factory-integrated MV-transformer-LV distribution package combining transformer, switchgear, protection, control, enclosure, and project interfaces.

For Prefabricated Substation, the approved single-line diagram and data sheet convert a factory-integrated MV-transformer-LV distribution package combining transformer, switchgear, protection, control, enclosure, and project interfaces into defined ratings, interfaces, component scope, tests, dimensions, and delivery records.

A prefabricated substation is defined as a coordinated MV-transformer-LV package assembled and wired before shipment. The single-line diagram, feeder schedule, transformer rating, protection, metering, auxiliaries, and supply boundary control the design.

The enclosure can accommodate a wider range of layouts, capacities, access aisles, component platforms, cable rooms, ventilation systems, and maintenance provisions than a deliberately miniaturized compact substation.
