Prefabricated Substations Delivered as One Complete Unit
Yuantong builds YB-series European-style box-type substations, compact substations and prefabricated substations from 10 kV to 35 kV. Each unit combines HV switchgear, a transformer and LV distribution in one weatherproof enclosure, so it can be delivered, set on a foundation and connected quickly. They are used for urban networks, industrial parks, oil and gas fields, and solar and wind farms. Every unit is routine-tested before it ships.

FAQ
Box-Type Substation FAQ
A box-type substation includes HV switchgear, a distribution transformer and LV distribution equipment in one enclosure. We configure each compartment to your single-line diagram.
Yes. We supply box-type substations with oil-immersed or dry-type transformers, depending on the site and your specification.
Yes. Box-type substations are widely used to step up inverter and turbine output to medium voltage. Send us the rating and site data for a recommendation.
The minimum order is one unit. Standard configurations typically ship 15–30 days after the order and deposit are confirmed; custom designs depend on the specification.
We design to IEC 62271-202 or GB standards, or to the standard named in your specification. A routine test report is supplied with every unit.
