OIL COOLED VARIABLE TRANSFORMER

We specialize in manufacturing Oil Cooled Variable Transformer which gives the best protection possible without the need of any external cooling source. In the offered transformers all the decisive components are fully submerged in oil, so finest cooling and protection from the environment is guaranteed. The adjustment of the rectifier can be carried out by means of a motor-driven variable ratio transformer or electronically via analog signals for constant voltage and current control.

The commutator surfaces of our coils are machine processes and hence very uniform and smooth functioning is carried out. It is well-known for proper collection of current by the carbon brushes thus reducing the heat generated. Our standard coils are 100 Amp, 150 Amp, 200 Amp. With these coils we assemble oil-cooled variautos from 100 Amp 3 Ph to 1200 Amp 3 Ph capacity. In high current rated models we utilize numerous coils with suitably rated balancing coils to accomplish the rated current. These variautos are normally motorized with geared mechanism.
