|
|
 1 or 3 phases- Vacuum varnished
- Power from 1 VA to 50 kVA
- Cheap and economical production due to several company locations
- Small transformers wound automatic
- Large transformers wound with a thick wire machine with 1700 mm width for the bobbin and automatic wire positioning
- More power due to optimisation via computer program
- Each transformer is calculated individually according to customer specification and standards

Description
|
|
|
Three-phase transformers, built as high current transformers. The mounting must be done in a way that a convection through the cooling channels is possible. The block terminals are shock proof conform to VBG4. With our impregnation under vacuum the transformers have a very low hum-noise.
