THE EQUIPMENT FAMILY
The rating is only the beginning.
Compare voltage ratio, impedance, losses, cooling, protection and maintenance alongside rated capacity. We match the requirement to manufacturer information.
Oil-immersed transformers
Distribution and power transformers for site and network connections. Assess cooling, oil containment and maintenance access.
Pad-mounted transformers
Enclosed outdoor distribution options. Confirm connections, access, protection and local requirements.
TECHNICAL CONSIDERATIONS
Select on the right basis.
Confirm ratings, compliance evidence and availability for the selected model.
REPRESENTATIVE SELECTION DATA
Cast-resin distribution range
| Parameter | Family / selection basis | Project consideration |
|---|---|---|
| 6 / 10 kV class | 30–2,500 kVA | 0.4 kV secondary in the published distribution range. |
| 20 / 35 kV class | 50–2,500 kVA | 0.4 kV secondary in the published distribution range. |
| Cooling | Natural air; forced-air option | Confirm enclosure, temperature rise and installation conditions. |
Selected SC(B) distribution range in manufacturer material reviewed August 2026. Ratings are configuration-dependent, not all available in every combination.
Request the model datasheet ↗Project selection checklist
| Parameter | Family / selection basis | Project consideration |
|---|---|---|
| Voltage ratio & frequency | Primary, secondary and system frequency | Match the utility or site supply and downstream equipment. |
| Rated power & loading | Required kVA or MVA, duty profile and growth allowance | Consider actual loading, redundancy and operating conditions. |
| Winding arrangement | Vector group, earthing and impedance | Coordinate with fault levels, protection and parallel operation where relevant. |
| Cooling & insulation | Dry-type or oil-immersed configuration | Confirm thermal class, cooling mode, ventilation and ambient conditions. |
| Losses & sound | Model-specific no-load, load-loss and acoustic data | Compare at the same rating, reference temperature and measurement basis. |
| Acceptance | Agreed routine tests and relevant type-test evidence | Confirm the test basis, witnessed activities and document handover. |
APPLICATIONS
Start with the operating duty.
Data centres
Coordinate transformation with distribution, resilience architecture and high-density load growth.
Commercial & industrial sites
Select around the load profile, available space, operating environment and maintenance access.
Storage & renewable interfaces
Assess step-up duty, power-conversion interfaces and the connection requirements.
