Transmission substation outdoor combined electrical compact substation10kV 12kV 35kV

Product Overview

The Compact Secondary Substation (CSS) is a highly integrated outdoor power facility, also known as a compact Substation and Compact Prefabricated Substation, enclosing medium-voltage (MV) switchgear, distribution transformers, low-voltage (LV) switchboards, and auxiliary equipment within a single protective enclosure. This Compact Prefabricated Substation supports power conversion from 10-35kV MV input to 0.4kV LV output. Featuring modular design with arc-test certified components, the enclosure of this compact Substation meets IP54+ protection standards, allowing direct installation in public-access areas like communities and commercial parks.

Type-tested for insulation strength and short-circuit withstand capability, the Compact Prefabricated Substation (CSS) incorporates an arc protection system and intelligent monitoring modules for remote condition surveillance. This compact Substation completes full-process power conversion from high-voltage intake to low-voltage distribution in a compact footprint, delivering safe and reliable end-point power solutions for urban distribution networks as a high-performance Compact Prefabricated Substation.
