摘要
An on-load tap-changer for dry transformers, having an electric insulating hollow casing extending around a virtual axis, wherein several electric contact sections are foreseen along a path on the inner surface of the hollow casing, which are electrically joined through the wall of the hollow casing and a selector contact in the inner of the cylinder which is moveable along the path and that's outer end is selectively connectable with one of the contact sections by a respective movement. Respective cables are foreseen to electrically connect the contact sections from the radial outer side of the hollow casing, wherein at least some of the cables have a respective surrounding outer insulation at least at their respective connected end.
