Abstract: A flexible medium voltage interconnection adapted to electrically interconnect receiving connectors of “bushings” of equipment stations. The interconnection comprises a conductive core including a metal conductor with, at each end thereof, an electrical connector adapted to mate the receiving connector of the bushing, and a flexible tube having at least an insulating layer of elastomeric material and covering the whole conductive core. The elastomeric material of the tube is preferably a synthetic terpolymer of ethylene, propylene and diene [EPDM] to increase the flexibility of the whole. In the method, the tube is expanded over the metal core of which the ends are foreseen with locking rings mating grooves of the tube in order to prevent a relative movement of the core with respect to the tube.

Abstract: A bushing device being either a “bushing” comprising an external standard interface cone on one side and a conical shape at the opposite side, or a “bushing well” having a single hollow conical shape comprising an internal standard interface cone. The bushing device is to be hermetically mounted in a hole of an electrical equipment, insulated with oil fluid or gas, and is foreseen of a metallic fixing flange having a diameter larger than the diameter of this hole. The bushing device is adapted to interconnect an electrical distribution cable external to the equipment with a device internal to the equipment. The equipment is for instance a transformer, a switchgear, a capacitor or a motor. The bushing device is made of an elastomeric material containing an anti-migratory additive, whilst the metallic fixing flange is preferably made of stainless steel adapted to be welded to the wall of the equipment.
