Isolation Transformer Cubicles


Isolation Transformers are dry type, natural air cooled isolation (separation) transformers where the primary (line) and secondary (load) side windings are electrically and galvanic ally separated from each other, thus, there is a functional insulation by design. Reliable designs w.r.t. location of transformers in power configurations as bypass, mains, input, inverter, output, etc.
