    • A joint for connecting two multilayer cables of the stator winding of a high-voltage generator located in the front part of the latter comprises the end zones (1) of the multilayer cables to be connected which comprise, in their turn, coaxially located conducting layers (2, 10), tubes (6, 8) of the conducting layers separated from each other with insulating layers (7, 9, 14, 15), jumpers (18, 20, 22, 24) connecting electrically the conducting layers (2, 10) to each other, and tubes (6, 8) of the conducting layers. Each insulating layer (7, 9, 14, 15) has a part facing the jumpers (18, 20, 22, 24) and shaped as a terminal truncated insulating cone (16). Each jumper (18, 20, 22, 24) consists of a plurality of elements shaped each as a section of a hollow cylinder limited by two generating lines. Each jumper (18, 20, 22, 24) carries an insulating bush (19, 21, 23, 25). Each terminal truncated insulating cone (16) and the truncated cones (26) of the insulating bushes (19, 21, 23, 25) carry thin-walled insulating cylinders (27, 28). The surfaces of the truncated cone (26) of the insulating bush (19, 21, 23, 25), of the terminal truncated insulating cone (16), of the two adjacent jumpers (18, 20, 22, 24), of the conducting layers (2, 10) connected with them and of the tubes (6, 8) of the conducting layers form, all together, an insulating chamber (30) whereas the surface of the jumper (24) and of the tube (12) of the outer conducting layer (10), of the terminal truncated insulating cone (16), of the truncated cone (26) of the insulating bush (25), of the thin-walled insulating cylinders (27, 28) form, all together, another insulating chamber (31). The insulating chambers (30) are connected with each other, with cooling channels (5, 13) and with the insulating chamber (31).
    • 用于连接位于其前部的高压发生器的定子绕组的两个多层电缆的接头包括待连接的多层电缆的端部区域(1),它们又包括同轴定位的导电层 (2,10),由绝缘层(7,9,14,15)彼此分离的导电层的管(6,8),将导电层(2,10)连接在一起的跳线(18,20,22,24) ,10)和导电层的管(6,8)。 每个绝缘层(7,9,14,15)具有面向跳线(18,20,22,24)并且成形为端子截顶绝缘锥体(16)的部分。 每个跳线(18,20,22,24)由多个元件组成,每个元件均被两个发电线限定的中空圆筒的一部分组成。 每个跳线(18,20,22,24)承载绝缘衬套(19,21,23,25)。 绝缘套管(19,21,23,25)的每个端子截顶绝缘锥体(16)和截头锥体(26)都装有薄壁绝缘筒体(27,28)。 两个相邻的跳线(18,20,22,24)的端子截顶绝缘锥体(16)的绝缘衬套(19,21,23,25)的截头锥体(26)的表面 与它们连接的导电层(2,10)和导电层的管(6,8)一起形成绝缘室(30),而跳线(24)和管(12)的表面 形成薄壁绝缘筒(27,28)的绝缘衬套(25)的截头锥体(26)的端子截顶绝缘锥体(16)的外导体层(10) ,另一绝缘室(31)。 绝缘室30彼此连接,具有冷却通道(5,13)和绝缘室(31)。
