 EXPERT
transformers have a modular design for easy installation - this
also allows the active parts to be embedded into the casting resin.
This guarantees high resistance to the electro-dynamic forces mainly
occurring in welding operations - as well as to external influences,
such as contamination and mechnical loads.
Our tranformers feature:
- Resistance welding techniques
- Heating engineering
- Electroplating technology
In the field of high-current processors, modular transformers with
high power density need to be installed as a power source, as close
as possible to the part to be welded - or to the heating resistors
in order to avoid high secondary side feed line losses.
The compact design is achieved by direct water cooling of the secondary
windings and the utilisation of C-cores out of grain oriented sheet
metal (Heating transformers with higher secondary voltage have indrect
cooling).
With rectification on the secondary side, EXPERT transformers can
be combined into single-phase and three-phase transformer-rectifier
units. The most important innovations are optimum weight, medium
frequency transformer-rectifiers for operation at static frequencies.
