Abstract

An oil-filled transformer switching frame is disclosed which includes at least one longitudinal channel element that is essentially formed by a wall that is curved in a U-shaped manner, for receiving in its inner region stranded conductors of an oil tank of an oil transformer. The wall of the channel element can include a first layer of mechanically strong, planar insulating material and a second layer of mechanically strong, planar insulating material that is adjacent to and fundamentally parallel to said first layer, the first layer and the second layer being connected to and spaced apart by a third layer of a mechanically strong, corrugated insulating material having hollow spaces that can be flooded with a fluid by way of lateral edges.
