Case studies

8000A transformer

To manufacture an open style transformer designed to offer the customer 8000A at 9 volts. Our design team were required to design the transformer to be built on a movable unit which would allow the operator the facility to move the transformer into place when testing equipment.

Bespoke solution

Our client required a solution to increase production within the foam packing business. Our team worked with the client to develop and manufacture a single phase variable transformer which was designed to be installed on stainless steel table. This solution was designed for heavy usage and to reduce cutting time when cutting foam sheets.

72kVA variable transformer

We were tasked by a motor manufacturer to design a test unit which required our team to design a system with a 72kVA transformer and a drive to offer the facility for the operator to change the voltage, current and frequency. The unit was designed and manufactured within a stainless steel enclosure with a user control panel to offer ease of use.
