3 phase systems
In addition to single-phase systems, Expert has designed and manufactured a large number of three-phase systems over the years. The use of three-phase systems is always required when very high power levels cause an unbalanced load in the supply network. The three-phase connection enables a symmetrical load on the supply network even at very high power levels.
The design of the individual transformers allows simple connection on the primary and secondary side. Various rectifier bridges such as B6 or M2 are used.
Expert offers solutions ranging from individual transformers with busbars to complete deliveries including control, switch cabinet and cooling.
Transformers in this area are built with and without rectifiers. Applications can be found in the following areas:
- Vacuum furnaces
- Electric upsetting
- Flash butt welding
- Projection welding
- Butt welding
