[0001] Variable bus duct for electrical wiring distribution [

The present invention relates to a flexible bus duct for electric wiring distribution, and more particularly, it provides a bus duct structure that is easy to work and maintain in a prefabricated manner, can be used not only as a bus duct but also as a separate cable, Electrical wiring distributions that prevent electrical interference between the male and female terminals of the positive and negative electrodes and the connecting ducts through insulation in the male terminal expansion ducts and the female terminal expansion ducts, The present invention relates to a variable bus duct.

Generally, bus ducts are mainly used for power wiring in large factories or buildings. When bus ducts are required to pass through areas where power can not be processed due to high current or where heat is generated, bus ducts .

When the conventional bus duct penetrates the concrete slab, a plurality of electric cables are positioned on the inner side, and a plurality of electric cables are positioned on the inner side of the bus duct installed on the lower surface of the concrete slab, and the bus duct is fixed to the fixed bolt and nut And fastened.

Such a bus duct wiring scheme is often wired on the floor or ceiling of a building. Especially when the concrete slab is penetrated through a building, it is rarely installed while maintaining the original level, It is difficult to construct according to the situation, but the panel and installation occupied area is relatively small, and there is no need of separate materials for installation and it is easy to expand due to low labor cost. In addition, it has excellent electrical characteristics such as voltage drop, shortening of air, and simplified maintenance of the system.

In recent years, bus ducts are rapidly evolving as advantages are recognized in large capacity systems. Compared to the past, the modern building system is getting bigger and requires a lot of energy. In accordance with this trend, the bus duct is installed in harmony with modern buildings with various advantages such as safe and low energy loss. to be.

However, since such a conventional bus duct is wired on the bottom surface of a building, there is a problem that it is difficult to construct the duct according to various areas and circumstances. Particularly, it is necessary to insulate the terminal board except the power connection part from the terminal board installed inside the distribution terminal box. It is difficult to realize the shape, and it is more difficult to make the bus duct distribution structure by the assembly method. In addition, there has not been proposed a structure which can be used not only as a bus duct but also as an individual cable.
