BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus duct installation device used for installing a bus duct of a bus duct main line system for carrying electric power in factories and the like and a method of using the same.

[0002]

2. Description of the Related Art In recent years, office automation, building intelligent orientation, and factory-designed CAM
With the shift to A, the electrical equipment capacity is increasing dramatically. In addition to high reliability, energy saving / space saving, and flexibility, the performance required of the main line system that conveys the electric power is also a major factor in disaster prevention due to the lessons learned from cable fires. . Therefore, instead of the cable construction method, a bus duct power trunk system is being adopted.

FIG. 14 is a sectional view showing an example of a bus duct used in a bus duct power trunk line system. In the figure, 1 is a bus bar, and this bus bar 1 is, for example, copper.
A material such as aluminum or copper is used, and the entire surface and the entire length of the material is plated with electric tin. 2 is, for example, a heat-resistant insulating material formed by coating a heat-molded product of a heat-resistant polyester sheet on the bus bar 1 in multiple layers, 3 is a side plate made of a U-shaped steel plate, and 4 and 5 are U-shaped steel plates, respectively. An upper plate and a lower plate, which are manufactured in the shape of a strip, and 6 are insulators that insulate and support the bus bar 1.
