Abstract: A winding fixing device and method for a hollow-cylindrical high-voltage winding are disclosed, wherein the winding fixing device includes a pillar-like element having two axial ends, each of the two axial ends being configured to be connected to a respective retaining element which is arranged transversely with respect thereto. Each of the retaining elements is configured to be movable along the pillar-like element and detachable therefrom. A positioning region for arranging a hollow-cylindrical high-voltage winding is formed between the retaining elements, and spacing elements are configured to move axially along the pillar-like element. The spacing elements are configured to radially fix the hollow-cylindrical high-voltage winding when placed between the retaining elements by applying a tensile force to the retaining elements.

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.

Abstract: An exemplary oil transformer insulation module includes at least a first flat layer and a second layer adjacent and substantially and parallel to the first layer. The first and second layers include planar first insulation material and are connected to and spaced apart from a third corrugated layer that is arranged between the first and second layers. The third layer includes planar second insulation material, has lateral edges, and is corrugated such that all the cavities formed by the corrugated form can be flooded with a liquid via the lateral edges.
