A Compact Secondary Substation (CSS) is a type tested and arc tested assembly comprising an enclosure containing medium voltage (MV) switchgear, distribution transformers, low voltage (LV) switchboards, connections and auxiliary equipment to supply LV energy from MV systems. These substations are typically installed in locations accessible to the public and ensure safety according to specified service conditions.
An eco-friendly solution offering the strength and durability of a concrete CSS with the lightweight characteristics of steel.
ABB compact secondary substations address worldwide industry-specific applications, is supplied globally to markets adopting the IEC standards, and accommodates local standards where these are aligned or overlap with IEC.
The UniPack family of CSS solutions have variants suited to a vast array of applications across segments including — but not limited to — renewables, industry, utilities, infrastructure and other grid applications.
While an ABB CSS will align to almost any segment, these solutions would best serve projects that benefit from its reduced lead time by use of a standard design and reduced shipping costs, which outweigh the need for strict adherence to a predefined site specification.
