Sinopower Transformer (Changzhou) Co. Ltd'sdry-type transformer adopts advanced domestic technology, with high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life. It adopts an intelligent signal temperature control system, which can automatically detect and display the working temperature of each three-phase winding, automatically start and stop the fan, and has functions such as alarm and trip settings.

Dry type transformers use high-quality cold-rolled grain oriented silicon steel sheets, and the iron core silicon steel sheets use 45 degree fully oblique joints to allow magnetic flux to pass along the direction of the silicon steel sheet joints. In key projects and major engineering projects in China, it is difficult to find traces of foreign dry type transformers
