Introduction

Three-phase transformers

T3UI Type

The three-phase transformers from the T3UI series are used on three phase energy systems either as security - isolation type transformer or step up - down transformer, for building into installations and industrial or power engineering devices, medical equipment and etc. At AST Engineering, we can custom design three-phase transformers to meet your exact requirements regarding primary and secondary voltages, power ratings, line frequency, agency approvals, etc.
