An insulating cover (1) is described, which is applicable to the statoric bars of large size electric machines. The objective of the present invention is to provide an insulating cover (1) that dispenses the use of resin for its fixation and enabling the checking of the conservation state of the end portions of the winding along the electric machine working life. This objective is achieved by means of an insulating cover for statoric bars of electric machines, the cover (1) comprising first (10) and second (20) faces positioned substantially parallel to each other and joined by at least one joining element (15) located in a substantially central portion of the faces (10) and (20), the element (15) being provided with at least one fixing means (17) to fix the insulation cover (1) to an end portion (29) of the winding of the electric machine.
L'invention concerne un couvercle isolant (1) s'appliquant sur des barres de stator de machines électriques de grandes dimensions. L'invention a notamment pour objectif de supprimer, grâce à ce couvercle (1), l'utilisation de résine pour la fixation de celui-ci et de permettre la vérification de l'état de conservation des portions d'extrémité de l'enroulement tout au long de la durée de vie de la machine électrique. Cet objectif est atteint au moyen dudit couvercle isolant (1) les barres de stator de machines électriques, lequel comprend une première (10) et une seconde (20) face, placées de façon sensiblement parallèles l'une à l'autre et assemblées par un élément d'assemblage (15) monté dans une portion sensiblement centrale desdites faces (1à et 20), cet élément d'assemblage (15) étant pourvu d'au moins un dispositif de fixation (17) servant à fixer le couvercle isolant (1) sur une portion d'extrémité (29) de l'enroulement de la machine électrique.
