Frequently Asked Questions

Does it support OEM/ODM customization?

Yes, we support comprehensive customization including power parameters, input/output voltage, IP protection levels, and specialized working environments (explosion-proof or high-temperature resistance).

What technical documentation is provided?

All goods are shipped with English manuals, product certificates, test reports, and wiring diagrams to assist with installation and customs clearance.

How are the transformers protected during long-distance shipping?

We use standard export-grade wooden crate packaging. The structural design of the transformer itself includes special fastening to resist impact during transit.

What is the typical energy saving compared to standard models?

Our Level 1 energy efficiency units reduce no-load losses by over 30% and load losses by over 20%, significantly reducing the Total Cost of Ownership (TCO).

Is the oil-immersed transformer suitable for coastal environments?

Yes, the fully sealed corrugated tank and optional corrosion-resistant coatings make it ideal for high humidity, high pollution, and coastal environmental conditions.

What is the expected service life of these units?

Thanks to the vacuum drying and advanced oil filling processes which slow down insulation aging, our transformers have a design life exceeding 20 years.
