What is needed for a 25 kVA replacement enquiry?
Share the existing nameplate details, required voltage ratio, cable entry arrangement, and available pad or enclosure drawing. The same kVA rating alone does not confirm that a replacement will match the existing installation.
Engineering Review
The voltage ratio, BIL, tap arrangement, terminal configuration, enclosure, insulating liquid, protection requirements, accessories and applicable standard will be reviewed for each project.
The product image illustrates this transformer family. Final enclosure dimensions and terminal layout must follow the approved project drawing.
Request a technical quotation with your specification, quantity and destination. For other ratings, view the single-phase pad-mounted transformer collection.
Before requesting a quotation
Confirm the fit for your project.
A product name or capacity is the starting point. Include these requirements so the proposal can be reviewed against your project.
01
Electrical requirements
Capacity, primary and secondary voltages, phase, frequency, and any specified connection, impedance or tap requirements.
02
Installation requirements
Describe the feed arrangement, cable connections, cabinet access and site layout. Include the project or utility specification.
03
Documents and supply scope
State the required drawings, tests or approvals, quantity, destination and project schedule. Identify any mandatory requirements before quotation.
What if some specifications are not known yet?
Send the information you have and mark unknown items as to be confirmed. For a replacement, an existing nameplate, equipment photographs and site constraints help define the review. Final ratings and supply scope must be agreed in the quotation and approved documents.
Project documents
The right document. For the right model.
Tell us which documents your project needs. Availability and applicable scope are confirmed for the proposed model and configuration.
Outline and connection drawings
State the installation, cable-entry and clearance requirements you need to check.
Request for your projectTest and approval documents
Name the required tests, standard or approval, and the model or configuration concerned.
Request for your projectRequest documents for your proposed configuration
Include the model or product type, capacity, voltages, frequency and destination. Ask for the report number, date and test scope so you can check that the documents match the proposed configuration. An individual report does not establish certification for every model or destination.
When reviewing a document, match the legal entity, model, rating, applicable scope and issue date to your proposed equipment.
