Abstract

The utility model discloses a busway which comprises a metallic outer shell and conductive bodies. The aluminum alloy outer shell is composed of a side plate and a cover plate. The side plate and the cover plate are connected to clamp the conductive bodies by a fastener. More than one heat-conducting insulating film is clamped among the conductive bodies and the side plate and between two conductive bodies. The definite electrical gap exists between the conductive bodies and the cover plate. In the utility model, because the side plate is connected with the cover plate to clamp the conductive bodies by the fastener, and more than one heat-conducting insulating film is clamped among the conductive bodies and the side plate and between two conductive bodies, the insulating films are clamped between the conductive bodies in block shapes. The uniform thickness of an insulating layer which is composed of the insulating films can be ensured, therefore the heat conducting performance and the electric performance of the insulating layer can be effectively controlled. The heat produced by the conductive bodies can be passed to the metallic outer shell by the heat-conducting insulating films and then is dissipated to the environment, and the generation of electric discharge phenomenon can be effectively prevented.
