Problems solved by technology

[0002] At present, in the power transmission, in the working environment with large power supply demand such as the workshop, the existing cable capacity is small, and the power needs to be transmitted through the bus duct. There are also certain problems in the existing bus duct, and the conductors in the bus duct will generate large In order to ensure the insulation between the conductors, the thickness of the insulating layer between the conductors is designed to be thicker, but its heat dissipation will decrease. If the thickness of the insulating layer is reduced, its resistance to breakdown under high temperature will decrease. Therefore, the heat dissipation and safety issues of the busway have always been a difficult problem in the research and development of the busway. The installation of the heat dissipation structure will lead to installation problems. The complex installation structure will lead to the cutting of the heat dissipation structure, forming a cold bridge, and affecting the heat conduction.

[0005] The above structure has the problem of heat dissipation partition at the connection node position, the heat dissipation is discontinuous, local heat concentration is easy to occur, and the heat dissipation efficiency is low
