Three phase transformers up to 10.0 kVA - 50.0 kVA


Electro-wind specialises in the manufacture of air cooled (AN) 3ph transformers. A naturally cooled transformer is the most efficient way change voltage at low power ratings. Normally built from an isolating design a 3ph transformer consists of an iron core with 3 limbs. Each transformer limb has an individual primary / secondary winding. The individual windings allow the input power to be isolated from the power output.

Electro-Wind offers any bespoke transformer that you may require. Electro-Wind offers all of the winding configurations including Delta, Star (also called wye), Skot and Zig Zag. The most common transformer connection is delta star Dyn11.

Electro-Wind has experience in high frequency transformers including 400Hz for frequency converters. These units are often oversized for compatibility with supply side harmonics and inverter drives.

Small auto wound transformers are commonly used when steeping up or down over a small voltage range. They are a cheaper and smaller than a larger isolating transformer and recommended when isolation isnít a factor.
