Transformers and package substations for data centres
A data centre runs around the clock, so transformer losses are paid for every hour. We select a low-loss transformer for your power scheme and build it to your drawing.
- Cast-resin dry-type transformers (TSL type) — for installation inside the building, close to the load: no oil, no oil pit needed.
- Energy efficiency classes 1–2 (SCB14, SCB18) cut no-load losses — the losses that run around the clock even when the hall is not fully loaded.
- Redundant scheme: two transformers per section, each loaded to no more than half. The table below is calculated for this load.
- Hermetically sealed oil-immersed transformers (TMG type) and containerised substations — for outdoor installation on site.
Annual losses: dry-type SCB10 vs SCB18 at 50 % load
| Rating, kVA | SCB10, kWh/year | SCB13, kWh/year | SCB18, kWh/year | Difference, kWh/year |
|---|---|---|---|---|
| 630 | 24 616 | 20 038 | 18 374 | 6 242 |
| 1 000 | 33 310 | 27 134 | 24 955 | 8 355 |
| 1 600 | 47 085 | 38 413 | 35 511 | 11 574 |
| 2 500 | 68 985 | 56 414 | 52 045 | 16 940 |
Annual losses = (no-load losses + 0.5² × load losses) × 8760 h. No-load and load losses are taken from the partner factory catalogue. Multiply the difference by your tariff to estimate the savings.
Ratings
Specifications, currents and all design options for each rating:
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
