Procurement FAQ

Common questions before sending a transformer RFQ

These answers help purchasing and engineering teams prepare a clearer first quotation request.

Is HEMU Transformers a factory website?

HEMU Transformers is positioned as a transformer supplier, sourcing and RFQ coordination site. Factory ownership, certificates and project cases are confirmed through formal supplier documents before purchase decisions.

What information helps start a transformer RFQ?

Share transformer type, capacity, voltage, phase, frequency, installation environment, standard, project country, quantity and drawings or data sheets if available.

Can I compare several transformer types?

Yes. Buyers can compare power, distribution, pad-mounted, dry-type and oil-immersed transformers when the site condition and project standard are still under review.

When are exact specifications confirmed?

Exact specifications are confirmed in quotation documents, technical agreement and signed contract after project requirements are reviewed.

Send transformer requirements for quotation review

Include transformer type, capacity, voltage, project country, standard and drawings if available.
