Low voltage dry-type transformers
Ruhstrat low voltage dry-type transformers are developed, manufactured and tested in accordance with relevant EC directives, European standards and VDE regulations, in particular DIN EN 61558.
- single-phase or three-phase design
- separate winding or autowinding (autotransformer)
- power range from 40 VA up to 2 MVA*
- voltage value up to 10 KV
- as energy saving transformer with a efficiency > 99 %
- in combination with a variable transformer connected in series, in order to steplessly regulate voltages in the output
- degrees of protection: IP 00, IP 20/IP 23 with steel-sheet enclosure, IP 54 with air/water heat exchanger or as oil transformer
* Higher power values are individually possible.
Examples of use:
- e. g. pre-magnetization transformers for the reduction of the inrush current, test fields, machine controls, marine engineering, resistance-heated industrial furnaces, glass melting plants, neutral earthing transformers etc.
