Compact Substations
YB-12/0.4 prefabricated substation (YB□-12/0.4) for 3.6–12 kV three-phase AC systems, integrating medium-voltage switchgear, distribution transformer, and low-voltage switchgear in a single factory-assembled enclosure. Engineered for power utilities, mining, building-materials plants, transport hubs, municipal infrastructure, and emerging applications such as large engineering-machinery power supply and photovoltaic generation. Supports all mainstream MV/LV equipment, accepts customized electrical schemes, and is energization-ready to cut on-site civil works and installation time. Manufactured to GB 17467, GB/T 11022, DL/T 537, IEC 62271-1, and IEC 62271-202.
Quick answer
YB Series Prefabricated Substation is an RFQ-configured compact substations for Industrial parks and Commercial centers. Confirm five inputs before quotation: voltage class, rated current, single-line diagram, installation environment, and destination standard.
Visible specifications and Product structured data use the same reviewed fact set.

Yes. Submit the project SLD, voltage class, rated current, installation environment, destination country, and preferred component ecosystem so the engineering team can review the quotation scope.
Industrial electrical equipment is configured by project drawings, electrical parameters, component brands, testing requirements, packing, and delivery terms. The site uses RFQ instead of checkout or public pricing.
The source product ID, category, source URL, and image URL are preserved for traceability. Public claims remain limited to supplied source material and RFQ-ready product descriptions.
Provide five core inputs: voltage class, rated current, single-line diagram, installation environment, and destination standard. Component preferences, quantities, delivery terms, and testing requirements improve quotation accuracy.
Use IEC 62271-202 / GB 17467 family, verify by product and project scope as the initial standard family, then confirm the exact model scope, destination requirements, technical agreement, type-test evidence, and FAT plan with the engineering team before production.
