Liquid-cooled transformers, 3TTW type
Purpose and design
Transformers equipped with a water-cooling system allow the transformer to be effectively cooled, while at the same time the losses are led outside the unit casing. This type of cooling is often used in power electronics or mining applications where coolant is available and used to cool the radiators. We offer indirect and direct water-cooled transformers. We manufacture transformers for any power and work conditions, as well as for required voltages. Transformers can be supplied in IP 23, IP 44 and IP 54 enclosures or in raisin flooded enclosures.
Upon agreement, we can manufacture a non- standard device with the required technical parameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
