Distribution Transformer Substations We Manufacture

YB series prefabricated substations and compact transformer substations from 50 kVA to 2500 kVA, 6-35 kV / 0.4 kV, factory-tested as complete units.

What Is a Distribution Transformer Substation?

A distribution transformer substation packages the transformer, HV switchgear and LV panel of a distribution substation into one compact, factory-tested unit – reducing site work and project time dramatically compared with conventional construction.

These units serve urban distribution, commercial developments, industrial sites and rural electrification where fast installation and a small footprint are priorities.

  • Integrated unit – transformer, HV switchgear and LV panel in one enclosure.
  • Factory tested – the complete unit tested before delivery.
  • 50 kVA – 2500 kVA – capacity range for distribution duty.
  • 50,000m² factory – enclosure fabrication, assembly and testing in-house.
  • 350+ employees – engineering, production and export teams.
  • OEM / ODM & wholesale – custom branding, packaging and volume supply.

YB prefabricated type

Complete substation in a weatherproof enclosure for utility and commercial projects.

Prefabricated Substation vs Conventional Construction

Conventional substations require months of civil work, equipment installation and on-site testing. A prefabricated substation arrives factory-tested and connects in days – cutting project time, cost and site risk.

For fast-track projects and remote sites, the prefabricated approach is increasingly the standard choice.
