Box-Type Substations Overview
Box-type substations, also known as prefabricated substations, compact substations, package substations, or pad-mounted substations, are complete power distribution units factory-assembled in weatherproof enclosures. QDTB prefabricated substations integrate transformer, HV switchgear, and LV distribution into a single compact unit, reducing installation time and costs. European and American designs cover 100-1,600 kVA, meeting IEC 61330 and GB/T 17467. As a leading prefabricated substation manufacturer, QDTB delivers turnkey solutions for urban networks, renewables, and industry.
Available Series
YB Series
The YB series prefabricated substations integrate transformer, HV/LV switchgear into a single compact enclosure. Equipped with S13 energy-efficient transformers for reduced no-load losses, suitable for urban power distribution, industrial parks, and residential areas.
ZGS Series
The ZGS series represents American-type package substations, designed for pad-mounted installation with enhanced safety features.
