PCT No. PCT/SU80/00161 Sec. 371 Date Jun. 25, 1981 Sec. 102(e) Date May 11, 1981 PCT Filed Sep. 25, 1980 PCT Pub. No. WO81/01223 PCT Pub. Date Apr. 30, 1981.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.
