30 kva 480v to 400v 3 phase transformer step up and down
30 kva 480v to 400v 3 phase transformer step up and down
Our transformers have special advantages and very different from others.
(1) All new raw materials.
(2) Full (100%) capacity.
(3) Low core loss with maximum efficiency and efficiency up to 99% reduces operating cost by 30%.
(4) Ultra quiet operation.
(5) Clear, comprehensive documentation and labeling.
(6) THREE YEARS warranty!
REMARK:
---Frequency CANNOT be converted by transformer.
---Single phase voltage to 3 phase voltage CANNOT be achieved via transformer.
In order to give you the best price, please kindly specify your requirements as clearly as possible.
OEM and ODM is welcome, we have professional and experienced engineer team for you.

Our transformers are setting new standards for quality – in design, manufacturing and testing.
Before leaving the LINGFRAN factory, every transformer must pass a series of rigorous tests, performed with advanced equipment, on a range of measurements.
(1) Appearance – visual check.
(2) Winding resistance.
(3) Insulation impedance.
(4) Voltage ratio. Phase angle displacement.
(5) Short circuit impedance and load loss.
(6) No load loss and current.
(7) AC voltage regulation.
Below are part of our testing instrument.
- Step 1Find your interested products by search keywords
- Step 2Contact the supplier by clicking ”Enquire” or “request meeting” button, otherwise, you also could consult our import consultant.
- Step 3After verifying your email, get response from suppliers or our trade manager will contact you as soon as possible
- Step 4Set up meeting with the Chinese supplier without language barrier
