Description

Plug in bus duct

The present invention relates to a plug-in booth duct, and more particularly to a booth duct that can prevent damage caused by moisture, such as water.

In general, a wiring method using an electric wire cable is widely adopted as a power wiring system, but a wiring system using a booth duct is adopted as a wiring system in a high-rise building or a large factory.

Because booth ducts and cables have a common point in that they have conductors and insulators, but compared to cables, booth ducts can carry large amounts of current through the conductors and protect the conductors and insulators as metal ducts. It is possible to expand and relocate, easy to deal with accidents, and easy management of the system.

An example of such a booth duct is shown in FIG. 1.

As shown in FIG. 1, the conventional booth duct 10 includes an upper duct 11 and a lower duct 12 and a space S partitioned between the upper duct 11 and the inner duct 12. It includes a bus bar 5 embedded therein.

The upper duct 11 includes a first horizontal portion 11a and a pair of first vertical portions 11b extending upward and downward from both sides of the first horizontal portion 11a.

The lower duct 12 includes a second horizontal portion 12a and a pair of second vertical portions 12b extending downward from both sides of the second horizontal portion 12a.

The lower duct 12 is inserted between the pair of first vertical portions 11b of the upper duct 11, with the second horizontal portion 12a facing the first horizontal portion 11a.
