Three-Phase Transformers

Three-phase transformers with stranded magnetic circuits differ from transformers with plate magnetic circuits (with Ш- and I-shaped plates) by smaller dimensions and weight at the same power, lower labour intensity during assembly and by efficiency up to 95%. Transformers of ТТ series are developed for application in high-voltage motor control circuits for mining and metallurgy industry.
