成果简介	NOVELTY - The connecting sleeve has an outer metal casing (8) that is fixed to the outer insulating layer (6), and contains its own inner insulating layer (3) of the coupling (12). The own inner insulating layer of the coupling is made in the form of an insert (9) tightly pressed against the end fittings (1) and supporting insulating protrusions (4) of the inner insulating layer of the conductor. The insert is covered by a ring around which a cavity (11) is made for connecting gas gaps, limited by the outer metal casing of the bus bar on which threaded coupling is installed. The insert is made of elastic insulating material and is located in a recess between the supporting insulating protrusions of the inner insulating layer of the bus bar end fittings. The ring is made non-hermetic from a semi-conductive rigid material. The internal insulating layer is installed with supporting insulating projections on which a semi-conducting layer of cylindrical shape is located. USE - Connecting sleeve for bus-bar with combined insulation. ADVANTAGE - The connecting sleeve increases reliability and maintainability due to the possibility of its disassembly and reduces local amplifications of the electric field. The sleeve eliminates gas cavities at the interface between the insert and the supporting insulating protrusions and increases the reliability of the device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the connecting sleeve. 1End fittings 3Inner insulating layer 4Insulating protrusions 6Insulating layer 8Outer metal casing 9Insert 11Cavity 12Coupling
