Each u-shaped capacitive insulating bus is composed of a straight middle part and two arm parts, wherein the two arm parts are respectively bent towards the same side of the straight middle part from the two ends of the straight middle part. The two arm parts of each u-shaped capacitive insulating bus of the capacitive insulating buses are placed downwards so as to be correspondingly connected with inferior wire outlets of the same phase of the equipment. The straight middle part of each u-shaped capacitive insulating bus is fixed onto the bracket by the hoop.
