Abstract: A coupling unit for two multilayer cables of a stator winding of a high-voltage generator, located in the end-face portion thereof, comprises terminations (1) of interconnected multilayer cables, wherein conducting layers (2,10) and conducting layer tubes (6,8) are concentrically arranged and separated from one another by insulating layers (7, 9, 14, 15), jumpers (18, 20, 22, 24) electrically coupling said conducting layers (2, 10) and conducting layer tubes (6, 8). A portion of each insulating layer (7, 9, 14, 15), facing the jumpers (18, 20, 22, 24) has a shape of an end insulation frustum (16). Each jumper (18, 20, 22, 24) is a totality of components made as a portion of a hollow cylinder limited by two planes. Each jumper (18, 20, 22, 24) carries an insulating bushing (12, 21, 23, 25). Thin-walled insulation cylinders (27, 28) are secured in each end insulation frustums (26) and in frustums (26) of the insulation bushings (19, 21, 23, 25).

Abstract: A coupling unit for connection of a generator high-voltage winding lead-out and a cable comprises a casing (1) wherein a generator high-voltage winding lead-out (5) with sheaths (6) and a cable termination (3) are arranged, their current carrying elements (8) being linked by a power jumper (9).

Abstract: A device for attachment of coil ends in a generator stator high-voltage winding includes insulation spacers (13) disposed on external surfaces of the coil end bars (16), auxiliary spacers disposed between coil end bars (16), a case (1), spring stops (15) anchored inside the case (1), and planks (14). The case (1) is made of two coaxial truncated-cone members (2 and 3) and a part of a torus member (4) made integral therewith and incorporating a joint (5) with a seal (6). Each plank (14) is arranged between two insulation spacers (13), and the insulation spacers (13) are arranged between the coil end bars (16) and the spring stops (15). The insulation spacers (13), the planks (14), the spring (15) and a side surface of the case (1) form cooling passages.
