Description
The axial current distribution can adjust itself freely in the conductors. Thus axial forces which occur in short-circuits as result of inevitable asymmetries, are avoided. Axial contraction forces have no effects in the foil conductor. In order to control the radial forces the winding insulation consists of prepreg, a pressboard sheet which is coated on both sides with non-cured resin. Following the winding process the low voltage windings are placed in a heating oven to go under a heating process for tightening and strengthening the mechanical construction of the coil. The low voltage outlets mainly consist of massive copper bars. They are welded to the conductor in either a cold welding/ press technic or with TIG welding process to achieve maximum conductivity.
