Title
(EN) RIGID BAR FOR ELECTRICALLY CONNECTING A MACHINE IN AN AIRCRAFT TURBINE ENGINE
(FR) BARRE RIGIDE POUR LE RACCORDEMENT ELECTRIQUE D'UNE MACHINE DANS UNE TURBOMACHINE D'AERONEF
Abstract
(EN)
Disclosed is an electrically conductive rigid bar (80) for electrically connecting an electric machine (70) of an aircraft turbine engine, characterised in that it comprises: - an elongate body (80a) made from electrically conductive material having a polygonal cross-section greater than or equal to 50 mm², and - an electrical insulation sheath (80b) that surrounds the body, at least one of the longitudinal ends (84a) of the body not being covered by the sheath and comprising a through-hole (86) in which a bolt (88) for fastening and electrically connecting this end is mounted.
