Abstract:
A system for interconnecting one of medium-voltage and high-voltage electrical cells housed in shielded, gas-insulated and hermetically sealed enclosures, comprising:sealed and insulative bushings having respective axial conductors, said respective axial conductors of said bushings being aligned in pairs and each having an accessible outside connecting end; an interconnecting device operable to electrically connect two adjacent ends of said axial conductors of adjoining bushings; a flexible insulative sleeve of elastically adaptable length surrounding said interconnecting device, said sleeve approximately coaxial with said axial conductors; and a removable fixing device which fixes the bushing to each annular end of said sleeve, wherein said sleeve has a longitudinal central portion which includes a projecting annular fold forming a return spring, and between said central portion and at least one of two annular flat ends, a longitudinal zone which includes a re-entrant annular fold so that the inside surface of said sleeve is locally in contact with said axial conductor at said zone, said inside surface being covered by a semi-conductive layer that is equal to the same potential as the axial conductors.
