Patent

CA 2279416

The invention relates to an arrangement for use in cable joints, particularly joints on bent cables. The cable joint comprises two cables (6, 7; 18, 19; 45, 46) and a splicing joint (9; 16; 43) applied between the cables. The arrangement is characterized in that it includes a support (1; 15; 40, 41) designed for application over the joint so that the parts (6, 7, 9; 16, 18, 19; 43, 45, 46) forming the joint, remain substantially immovable in relation to each other, and that it includes at least one securing element (11, 12; 21, 22; 50, 51) by means of which the support is resiliently secured to the cable, and said securing element being capable of absorbing dimensional changes of the cable due to thermal expansion or contraction. The invention also relates to a rotating electric machine comprising a stator with windings drawn through slots in the stator, and a rotor, the machine being characterized in that it includes the arrangement described for cable joints.

Cette invention se rapporte à un dispositif utilisé dans des jonctions de câbles, notamment des jonctions placées sur des câbles coudés. Une telle jonction de câbles se compose de deux câbles (6, 7; 18, 19; 45, 46) et d'une épissure (9; 16; 43) appliquée entre les câbles. Ledit dispositif se caractérise en ce qu'il comprend un support (1; 15; 40, 41) conçu pour être appliqué sur la jonction, afin que les parties (6, 7, 9; 16, 18, 19; 43, 45, 46) formant la jonction restent sensiblement immobiles les unes par rapport aux autres et en qu'il comprend au moins un élément de fixation (11, 12; 21, 22; 50, 51) au moyen duquel le support est fixé de manière élastique sur le câble, cet élément de fixation étant capable d'absorber les changements de dimensions du câble dus à la dilatation ou à la contraction thermique. Cette invention se rapporte également à une machine électrique tournante comprenant un stator pourvu d'enroulements amenés à passer à travers des fentes ménagées dans le stator ainsi qu'un rotor, cette machine se caractérisant en ce qu'elle comprend le dispositif pour jonctions de câbles décrit ici.
