ABSTRACT A coupling unit of two multilayer cables of a stator winding of a high-voltage generator, located in the end- face portion thereof, comprises terminations of multilayer cables, wherein conducting layers are concentrically ar- ranged and separated from one another by insulating lay- ers, jumpers electrically coupling said conducting layers. A portion of each insulating layer, facing the jumpers has a shape of an end insulation frustum. Each jumper is a totality of components made as a portion of a hollow cy- linder limited by two planes. Each jumper carries an in- sulating bushings. Thin-walled insulation cylinders are se- cured in each end insulation frustums and in frustums of the insulation bushings. The surfaces of the frustum of the in- sulating bushing, the end insulation frustum, two adjacent jumpers and conducting layers coupled thereto form an in- sulation chamber. The surface of the jumper, the tube of the exterior conducting layer connected to said jumper, the end insulation frustum, the frustum of the insulating bushing, the thin-walled cylinders form an insulation cavity. The in- sulation chambers communicate with one another and with the cooling ducts and with the insulation cavity. The present invention permits direct cooling of multilayer cables of a stator winding, reduction of the dimensions of the coupl- ing unit of two multilayer cables of a high-voltage generat- or stator winding. The use of high-voltage generators re- sults in saving of electrical materials.
