| RUHSTRAT toroidal core transformers correspond to the currently valid instruction of DIN VDE and EN. Due to their low power loss RUHSTRAT toroidal core and limb core transformers work economically and have a low energy consumption. During the production process they undergo a resin impregnation under vacuum with subsequent oven drying. This insulation provides a long service life of the transformers and high protection against external mechanical impacts.
- single-phase or three-phase design
- separate winding or autowinding (autotransformer)
- power range from 20 VA up to 40 kVA*
- degrees of protection: IP 00 (bandaged), IP 20 with steel-sheet enclosure, IP 54 fully cast construction (protection class 2)
* Higher power values are individually possible.
Examples of use:
- test fields, machine controls, high-current transformers as toroidal core transformers, completely cast construction, for resistance-heated industrial furnaces, galvanical equipment, glass melting plants etc.
