Three-phase transformer Type DTI

Within the range up to 1,500 kVA, OpenSupply sells three-phase transformers with an input voltage of up to 1000 V, and a design and construction in accordance with EN 61588 or VDE 0570, and other standards, such as UL / CSA, as well.

OpenSupply carries a broad range of transformers that are suitable for many different applications. High-quality materials and vacuum impregnation are used in the construction of the transformers, for example in the Type DTI three-phase transformer.



Insulation transformers are net transformers with a nominal voltage on the input side and / or an output side over 1000 V. The same applies to net transformers with an output voltage (s) of more than 1 kV to 15 kV (for instance when generating anode voltages for transmitter tubes).
