Abstract
A winding arrangement for an electric installation has an electric conductor and a plurality of cooling ducts. The electric conductor is coiled up forming several layers around an axis. Each cooling duct extends between a pair of adjacent layers of the coiled electric conductor in axial direction through the winding arrangement and in tangential direction not entirely around the axis. The cooling ducts of the plurality of cooling ducts are distributed among more than one pair of adjacent layers such that the winding arrangement is substantially cylindrical.

1-12. (canceled)
A winding arrangement for an electric installation, the winding arrangement comprising:
- an electric conductor coiled up around an axis and forming plurality of layers;
- a plurality of cooling ducts each extending between a pair of mutually adjacent layers of said coiled electric conductor in axial direction through the winding arrangement and in a tangential direction not entirely around the axis;
- each layer of said electric conductor contacting at least one said cooling duct and said cooling ducts being disposed in a spiral arrangement for making a uniform cooling on each turn;
- and
- said cooling ducts of said plurality of cooling ducts being distributed between more than one pair of said adjacent layers to render the winding arrangement substantially cylindrical.
