Built Around Real Project Requirements
Transformer selection affects loss level, short-circuit performance, site safety, installation space and long-term operating cost. Ziyao Power supports project teams with cast-resin dry type transformers, sealed oil immersed transformers and energy-saving transformer platforms configured around voltage, capacity, insulation, cooling and installation requirements.
Project-based configuration
Transformer capacity, voltage ratio, vector group, impedance, enclosure and accessories can be reviewed against drawings and tender specifications.
Indoor and outdoor options
Dry type transformers are suited to indoor electrical rooms, while sealed oil immersed units serve outdoor distribution, utility and industrial feeder applications.
Test documentation support
Routine test records, nameplate data, outline drawings and packing information can be prepared for engineering approval and shipment review.

Technical FAQ
Common Buyer Questions
How should buyers choose between dry type and oil immersed transformers?
Dry type transformers are commonly selected for indoor rooms where fire safety, low maintenance and clean installation are important. Oil immersed transformers are often preferred for outdoor distribution, utility feeders and projects where higher capacity and long service life are priorities.
What information is needed for a transformer quotation?
A practical quotation should include capacity, primary and secondary voltage, frequency, vector group, impedance, installation environment, enclosure requirement, accessories and the applicable standard or project specification.
Can transformer drawings be prepared before production?
Yes. Outline drawings, nameplate details, terminal arrangement and accessory configuration can be prepared for technical approval before manufacturing begins.
