Medium Voltage Transformer

Overview

Suitable for stepping-down medium voltage power sources for low voltage applications (such as load testing). Nearly any desired medium voltage power source can be tested by combining this transformer with an Simplex load bank. The transformer can be delivered to the job site together with the desired load bank, in a pre-connected, seamless package mounted on a trailer.

We are experts at building products that meet our customer's exact requirements. Contact Simplex if your job specifications require additional options or considerations.
