Buying for a U.S. site? Explore pad-mounted, dry-type, power and unit-substation transformers, with the utility requirements and installation details in view from the start.
TRANSFORMERS FOR YOUR SITE
Start with the installation.
An outdoor distribution pad, an indoor power room and a utility substation call for different equipment. Choose the arrangement first, then work through the ratings.
Power transformers
For utility substations, renewable grid connections and large industrial loads. View the oil-immersed power range.

Pad-mounted transformers
Outdoor distribution equipment with enclosed cable connections. Compare single- and three-phase arrangements.

Unit-substation transformers
For installations connecting the transformer to adjacent switchgear. Cable boxes, bus connections and layout matter as much as the rating.

BEFORE YOU REQUEST A PRICE
Same kVA. Not always the same transformer.
Two quotations can look similar until you compare the connections, losses or required tests. Send the utility specification or equipment schedule with your enquiry so those differences can be addressed early.
- Supply & load
- 60 Hz, kVA or MVA, primary and secondary voltages, winding connections, impedance and tap range. Include the load profile if it is available.
- Connections
- For pad-mounted equipment: radial or loop feed, connector type and protection. For a unit substation: incoming and outgoing connections, cable boxes and adjacent switchgear.
- Site conditions
- Indoor or outdoor location, temperature, altitude, sound limits and available space. For a replacement, add the outline dimensions and cable entry positions.
- Approval & tests
- State the required IEEE/ANSI C57 parts, editions, loss or efficiency requirements and witness tests. Any requested listing must cover the actual manufacturer, model and ratings.
A laboratory accreditation or type-test report is not a blanket product listing. Check the complete document for the offered design.
APPLICATIONS & INSTALLATIONS
Where will the equipment work?
Data centers
Indoor power distribution, UPS interaction, losses, sound and access for maintenance.
Solar / PV
Inverter step-up duty, collector voltage and the utility interconnection.
BESS / energy storage
PCS connections, charging and discharging cycles, and the station arrangement.
Utility substations
Network expansion or replacement, voltage regulation and fault duty.
Pad-mounted installations
Outdoor distribution with enclosed connections and a defined cable compartment.
Unit substations
Transformer and switchgear connections planned as one installation.
FROM QUOTATION TO SITE
A few details are easier to settle before the order.
Share your required delivery date and destination at the quotation stage. Drawings, inspection and transport all need room in the programme.
Factory testing informationWhat should I send for a replacement?
The old nameplate, photographs of all sides, outline dimensions and connection details. Mention any increase in load or change to the supply. This helps avoid an electrical match that will not fit the site.
Can we witness factory testing?
Include the tests, witness points and reporting you need in the enquiry. The agreed inspection plan and schedule should be part of the order.
What is included in delivery?
The quotation should identify the delivery point, packing, shipping documents and responsibilities for unloading. Installation, commissioning and on-site support need an agreed scope; they should not be assumed to be included.
What if the specification is incomplete?
Send what you have, together with the state, application and intended delivery date. A single-line diagram or utility document is useful, but you do not need a finished equipment schedule to start a conversation.
