ABB Package Secondary Substation

Compact Substations (CSS) are used in secondary distribution networks to transform energy between medium voltage (MV) and low voltage (LV). A CSS is a type-tested and arc-tested unit housed in an enclosure that integrates MV switchgear, distribution transformers, LV switchboards, connections, and auxiliary equipment. They are commonly installed in publicly accessible areas and are designed to ensure safe, reliable operation and full protection in line with specified service conditions.
