Abstract

An electric device, for example a track transformer, connects to a high-voltage line. The electric device has a magnetizable core, at least one winding which is arranged in the vicinity of the core, and a housing which is filled with an insulating fluid and in which at least one winding is arranged. The core is arranged at least partly outside of the housing. In order to allow a stable mounting of a core formed of two halves, the core is arranged completely between two opposing pressing plates, between which tension elements for clamping the core extend.
