Abstract: A stator of a generator, which stator comprises a housing accommodating a slotted magnetic core 2, a dielectric oil-separating cylinder 4 arranged next to the internal surface of the magnetic core, and a winding composed of two series-connected half-windings 7, 8, each composed, in turn, of high-voltage elements 6. The high-voltage elements 6 of one half-winding 8 in the slotted part of the stator are placed in insulation sleeves 14 which have hollow projections 15 on their internal surfaces. Placed between the hollow projections is a thermosetting compound. The part of each insulation sleeve, which extends beyond the slotted part of the stator, has a cylindrical portion integral with a cone-shaped cable-type termination reinforced with current-carrying layers.

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.
