MULTI-PHASE POWER SUPPLY BUS FOR ELECTRIC POWER TRANSMISSION, METHOD OF MANUFACTURING THEREOF AND SWITCHING CABINET, INCLUDING SUCH POWER SUPPLY BUS Russian patent published in 2020 - IPC H05K1/14 H05K3/46 H02G5/00 H02B1/20 

FIELD: electricity.

SUBSTANCE: invention relates to a multi-phase power supply bus for electric power transmission, a method for its production and a switching cabinet including such a bus. Multiphase power supply bus (1) comprises optional base (2) layer of insulating material, first (4a) conducting layer of thin sheet metal, first (6a) layer of insulating material on first (4a) conducting layer, second (4b) conducting layer of thin sheet metal on insulating layer (6a) and second (6b) layer of electrically insulating material installed on second (4b) conducting layer. First and second conducting layers (4a, 4b) can contain coating (14) of electrically insulating material, and the first and/or the second insulating layers (6a, 6b) contain gaskets containing each layer (6) of rigid insulating material. At least one of gaskets of layers (6a, 6b) is glued to electrically insulating coating (14) of first and/or second conductive layer (4a, 4b), and/or at least one of gaskets layers (6a, 6b) is glued to conductive surface of uncoated first and/or second conductive layer (4a, 4b) by means of glue (7).

EFFECT: providing a multiphase power supply bus, which is easy to manufacture and has a low tendency to layer separation in case of electric short circuit, providing a method of making such a tire, as well as a switching cabinet, which includes such a bus, which can be manufactured at reduced costs.
