Isolation transformers are used to create galvanic isolation between two electrical networks. The transformer can convert the voltage from higher to lower or it can be the same on both sides of the transformers.

Trafotek has long experience in manufacturing isolation transformers. The isolation transformers are designed and manufactured with the same quality standards as our distribution transformers.
