DISTRIBUTION TRANSFORMERS

OIL FILLED TRANSFORMERS

INFORMATION

Since 1998 OTDS has manufactured its own distribution and power transformers.

Our transformers are used worldwide in some of the harshest environments and we are very experienced in designing and complying with various national standards for each of our international markets.

We offer standerdised transformers used by UK, European and Middle Eastern clients which enables us to provide competitive pricing along with excellent lead times.

Whether our client requires directly mounted HV/LV switchgear, MCCBs or special terminal arrangements, we are able to provide a competitive, tailored designed transformer.
