Abstract A resin impregnated electrical bushing. The bushing (1) comprises a wound structure (2) formed by winding electrical grade crepe paper or craft paper (3) on a hollow central conductor rod (4) with conductor foils (5) inserted at regular intervals radially within the paper insulation and impregnated with an electric grade epoxy resin (6). The central conductor rod comprises a plurality of circumferential grooves (7) along the outer surface thereof in radially spaced apart relationship having the impregnating resin penetrating into the grooves to provide a mechanical interlock between the resin impregnated solid mass of paper and the central conductor rod and to prevent delamination between the resin impregnated solid mass of paper and the central conductor. L'invention concerne une traversée électrique imprégnée de résine. La traversée électrique (1) comprend une structure d'enroulement (2) formée par enroulement d'un papier crêpé ou d'un papier kraft (3) de qualité électrique sur une tige conductrice centrale creuse (4) avec des feuilles conductrices (5) insérées radialement à intervalles réguliers à l'intérieur du papier isolant et imprégné de résine époxy de qualité électrique (6). La tige conductrice centrale comprend une pluralité de rainures disposées en cercles (7) le long de sa surface extérieure selon une relation radialement espacée dans lesquelles la résine d'imprégnation pénètre afin de former un verrouillage mécanique entre la masse solide de papier imprégnée de résine et la tige conductrice centrale et d'empêcher la déstratification entre la masse solide de papier imprégnée de résine et la tige conductrice centrale.
