FAQ

Q: What is the biggest advantage of dry type transformer compared with oil immersed transformer?

Dry type transformer adopts epoxy resin fully sealed structure, no oil leakage, no fire hazard, completely maintenance-free, safer and more environmentally friendly. It is more suitable for indoor and densely populated scenarios, while oil immersed transformers are more suitable for outdoor remote areas.

Q: Can you customize 50Hz/60Hz and special voltage parameters?

Yes. We support full customization of frequency (50Hz/60Hz), tapping range, protection grade, capacity and special voltage ratio to meet different national grid standards.

Q: What is the energy efficiency grade of your dry type transformers?

Our products support Grade 1 and Grade 2 high energy efficiency, with lower operation loss and longer service life, meeting global energy-saving and environmental protection requirements.

Q: How long is the product warranty and service life?

We provide 2-year free warranty and lifelong technical support. The normal service life of the transformer can reach more than 25 years.

Q: Is your product compliant with international standards for export?

All products comply with IEC 60076, IEEE and GB international standards, and can provide complete test reports and certification documents to support customs clearance and project bidding.

Q: What protection grades are available for selection?

Standard IP20, optional IP54 and IP65. Higher protection grade can effectively prevent dust, rain and foreign matter invasion, suitable for harsh outdoor environments.

Q: What is your delivery time?

Standard models take 20-30 working days. For urgent orders, we can arrange priority production to shorten the delivery cycle.
