Description

Multi-stage Power Distribution Cable Tray {Multi-stage Power Distribution Cable Tray}

The present invention relates to a multi-stage distribution cable tray, and more particularly, to a multi-stage distribution cable tray that is installed at the bottom of a ceiling of a building to facilitate wiring of a plurality of cables.

It refers to a device that is installed between cable trays and at the bottom of the wall or ceiling of a building to facilitate wiring of various cables that are wired to the building.

Such a cable tray is usually installed so as to be positioned at the lower end of the ceiling, so that the cable is positioned between the lower end of the ceiling and the cable tray, and is configured to be wired.

For example, conventionally, as in Document (1), a cable tray structure has been proposed that is installed at the bottom of the ceiling of a building so that a cable intended for wiring can be routed through a cable tray.

However, when the conventional cable tray structures forming the structure as in Document (1) are installed and used at the bottom of the ceiling, the wiring of cables placed on the top of the cable tray can be easily achieved, but when the number of cables is increased, There was a problem that the cable wiring process was easily made only when the cable tray was additionally installed.

In addition, after installation, it is difficult to change the wiring location of the cable, and if you want to change the wiring location, you need to install a separate cable tray after separating the installed cable tray, or additionally install a cable tray structure. However, there was a problem that unnecessary work costs or installation costs were increased.
