Abstract (en)

[origin: WO9933074A2] A switch gear station comprises at least one switch gear and at least one transformer/reactor comprising at least one winding (1) including at least one electric conductor (2). The conductor has an insulation system comprising an insulation (4) formed by a solid insulation material and, inwardly of the insulation, an inner layer (3) having an electric conductivity which is lower than the conductivity of the electric conductor but sufficient to cause the inner layer to operate for equalisation as concerns potential and, accordingly, equalisation as concerns the electric field exteriorly of the inner layer.
