For high voltage transceivers, the over voltage winding of which is carried out as layer winding and which have a step switch in the star point, an arrangement has already been proposed in which the high voltage connection and the star point channel are made at the star point channel with regard to the change in the circuit voltage, as well as an appropriate structure. v, the step winding is worn outwards.

This conductive lining strip strip consists of conductive Qu * mtreifin, which, forming a long strip, also overlapping, are attached to several parallel insulating material-IAngatralfen. The edge longitudinal strips are formed, for example by means of binding stapling, so that they can be peeled off from the transverse strip again at a later date. The last measure makes it possible that after the introduction of the conductive covering strip strip and the formation of the insulating material tarpaulin within the oil, the longitudinal strips of the Xoit covering strip strips are removed and they are now transformed into a spatial deformation Waneohea uagekipppt viordeü.

Solone oil channels form under Uautändan elsktrisoh sobwtoh * places, since oil has a significantly lower electrical strength than oil-impregnated paper and since oil-impregnated paper also has a smaller dielectric constant (about 2, 3) , oil-soaked paper (about 3, 2) is better From dissta arund oil gaps become old, oil-soaked paper in electrical maintenance. In such cases, ss can be advantageous ssiA, such oil channels can be arranged and connected to each other with the help of control panels, such as oil channels. The above invention, which aims to change the electrical stress on Isollerflansohen sum, can also be used for the layer and flange insulation within the strand of a high-voltage wrap.
