Abstract: The invention relates to a medium frequency transformer, which for example, insulates primary DC intermediate circuits from secondary DC intermediate circuits in a DC/DC transformer. The inventive medium frequency transformer has a two-part core, in addition to a primary winding and a divided secondary winding, a first and a second part of the divided secondary winding being configured on a respective side of the primary winding. Each winding preferably consists of a bundle of moulded hollow-cored conductors that are insulated in common and are traversed by a liquid coolant.

Abstract: A stationary induction machine including a winding (2) including an elongate, flexible cable (1), having an electric lead (7), and a cooling device, arranged, with the aid of a coolant, to divert excess heat generated in the lead during operation of the induction machine, which lead is in the form of a tube and surrounds a continuous channel (10) for the circulation of said coolant. In accordance with the invention, the cable includes a cooling tube (4) of a polymer material that is arranged in the lead and forms said channel. The invention also relates to a cable for such an induction machine.
