Prefabricated Substation Basics — When to Use a Box-type Substation
What a YB□-12 prefabricated substation integrates, how it saves site work, and the key specs to confirm before ordering.
A prefabricated (box-type / pad-mounted) substation packs HV switchgear, a transformer and LV switchgear into one weather-proof enclosure, assembled and tested in the factory.
Why choose it
- Less civil work: only a concrete pad is needed on site.
- Faster commissioning: factory wiring and type tests shorten the on-site schedule.
- Compact footprint: ideal where space is limited (urban blocks, industrial parks, mines, roads).
What to confirm before ordering
- Transformer capacity: typically 200–1600 kVA
- HV side: XGN15-12 RMU or KYN28A-12
- Transformer type: SCB18 (dry) or S22-M (oil)
- Enclosure protection: IP54; ventilation or air-conditioning for dry-type units
