Transformer 630 kVA 10/0.4 kV — hermetic oil-immersed (TMG type) and cast-resin dry-type (TSL type)
630 kVA power transformers from the partner factory: hermetic oil-immersed, wound-core and amorphous-core, cast-resin dry-type. HV 6; 6.3; 10; 10.5 or 11 kV, LV 0.4 kV, vector group Dyn11 or Yyn0. Hermetic oil-immersed units are the same type as TMG, cast-resin dry-type units the same type as TSL; dimensions and connections are agreed for your project.
- LV rated current, 0.4 kV
- 909 A
- HV rated current, 10 kV
- 36.4 A
- HV rated current, 6 kV
- 60.6 A
- Active power at cos φ = 0.8
- 504 kW
- Active power at cos φ = 0.9
- 567 kW
- Active power at cos φ = 0.95

Data from the partner factory's catalogue. Energy efficiency class per GB 20052-2024. Annual no-load losses = no-load losses × 8760 h. Where load losses are given as two figures, the first is for Dyn11, the second for Yyn0.
How we work
- Questionnaire or specificationSend us a questionnaire, specification or drawing. Within one working day we will reply with an indicative price and lead time; the firm price follows after engineering review.
- Engineering to your requirementsThe factory prepares drawings to your specification: voltages, vector group, losses, dimensions, bushings. We agree them with you before production starts.
- Contract and prepaymentWe work under a supply contract with a Russian legal entity. The manufacturing time is fixed in the contract.
- Manufacturing 25–45 daysStandard manufacturing time at the factory is 25–45 calendar days from production start.
- Factory acceptanceFactory acceptance tests. We send photos and video of your transformer and the test reports before shipment.
- Delivery and documentsDelivery to site, customs clearance, technical passport and test reports in Russian.
Partner factory
- Factory quality management system to ISO 9001, ISO 14001 and ISO 45001
- 20 transformer types have passed state type tests in China
- Built to the customer's drawing and requirements, including non-standard voltages and designs
- Energy efficiency classes 1–3 per GB 20052-2024: you can choose a transformer with minimum losses
