[0001] POWER CABLE TRAY STRUCTURE FOR BUILDING [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a structure of a power cable tray, and more particularly, to a structure of a power cable tray in which a plurality of power cables are accommodated to replace a generated power cable immediately.

Generally, a cable tray is installed adjacent to a ceiling of an underground parking lot of a building in order to distribute various lines such as high-voltage electric wire, communication line, and telephone line of a building to each household.

These building cable trays are used when distributing lines of electric wires, communication lines, telephone lines, etc. in various forms, and they are made of stainless steel and used.

A general tray simply supports the cable, and there is no technology that can be instantly replaced when a cable is broken in one of the cables.

Therefore, in recent years, there is a need for a research on a technique capable of immediately replacing a power cable in which abnormality occurs, by storing a plurality of power cables.
