2. when the bus is arranged, partial sections need to use hoisting structures, and due to the fact that height difference exists between installation bases of building structures and certain installation errors exist in arrangement of the bus, the hoisting structures used for installing the bus need to have certain adjusting functions, and the traditional hoisting structures do not have the adjusting functions, so that the hoisting operation of the bus has certain difficulty in height adjustment;

3. the supporting base is of a steel (conductive) structure, and an insulating block needs to be installed in order to keep insulation with the shell supporting beam, so that the supporting structure of the phase-isolated bus is complex, and the structural strength of the whole supporting base is weakened due to the existence of the insulating block;
