30kva step down transformer calculator step up transformers

 

Transformer Features

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.

Processing Equipment

Our transformers are setting new standards for quality – in design, manufacturing and testing.

Finished Transformer
Without or with enclosure (1.5-2mm thickness).
Pre-shipping Tests

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.
