Description

{PROTECTION STRUCTURE FOR POWER TRANSMISSION LINE OF APARTMENT}

The present invention relates to a power cable protection device in a multi-family housing complex, and more particularly, to a power cable protection device in a multi-family housing complex that can selectively install on a ceiling or floor of a building in a multi- And more particularly, to a power cable protection device in a multi-housing complex that is capable of easily preventing a fire due to disconnection by suppressing a rise in temperature of a cable when a certain temperature outside of the protection pipe is supplied.

Generally, a buried pipe is installed in the apartment complex for collective construction management.

Inside these buried pipes, electric wires and communication cables for supplying electricity are accommodated, so that electric power necessary for each home or office is supplied.

Since the buried pipe is buried in the ground to prevent exposure to the outside, since the buried pipe is not buried in the ground, the buried pipe is not exposed to the outside, so that the buried pipe is not damaged, The communication cable is prevented from being damaged.

The substation is usually installed on the ground. In such a substation, the high-voltage electric current must be transferred. Most of the high-voltage electric wires are exposed to the outside. The high-voltage electric wires exposed to the outside are short- It is easy to induce, and due to the harshly constructed high-voltage electric wire, there is a problem such as hatching the surrounding scenery, and the high voltage electric wire is installed in the underground.

When a high-tension wire is installed in the underground, the buried pipe for laying the wire is buried in the ground to prevent the high-tension wire from being exposed to the outside, thereby solving the problems caused by the external interference and the surrounding landscape .

Conventional cables are installed on ceilings or floors of buildings in apartment houses, but there are problems such that there is no protective pipe for protecting the cables or a fire due to disconnection occurs when the cable temperature rises.
