How about the anti-dust performance of the enclosure?

Tight sealing structure reduces dust ingress to protect internal winding and core.

What is the expected service life under dusty site conditions?

Normally 30 years under correct installation and regular maintenance.

Do you provide installation guidance or technical documents?

Yes, operation manual and technical drawings will be supplied together with goods.

What information should I provide to get an accurate quotation?

Please provide rated capacity, voltage ratio (HV/LV), vector group, tap range, frequency, winding material, cooling method, installation environment, and required certifications. The more details you share, the more precise the quotation will be.

Do you offer OEM/ODM manufacturing service?

Yes, we provide OEM and ODM services. We can manufacture transformers under your brand name, with your specified label design, packaging, and technical parameters, subject to a minimum order quantity.
