Description

{Convenience-enhancing underground distribution cable fixing device for installation in electric power yard}

The present invention relates to an underground distribution cable fixing device that improves convenience for installation in a power district.

Electric poles and overhead cables standing in a disorderly manner in downtown areas and residential areas spoiled the aesthetics of the city and caused frequent power outages during natural disasters such as typhoons and floods.

In comparison, underground lines are advantageous for supplying urban loads because multiple lines can be installed, and because the cables pass underground, they are safer than overhead lines and are advantageous for creating a pleasant urban environment by improving aesthetics.

In addition, the view of the road is improved because electric poles or cables are not exposed, and the identification of signals and road signs is improved, which improves traffic safety. Since the sidewalk can be used widely, it is suitable for pedestrians as well as people using strollers or wheelchairs. It has the advantage of providing a safe and easy-to-use walking space.

In addition, it has many advantages that can harmonize with the environment, such as less impact from natural disasters.

The prior art as a device for fixing such underground lines includes Patent Registration No. 1209242 (Underground Transmission and Distribution Cable Support Device), in which the cable mounting unit is spaced a certain width apart from the rail to be fixed to the upper part of the utility port. We proposed a configuration that allows for installation in multiple locations and facilitates the wiring of a large number of cables and additional wiring.

However, in the prior art, when work had to be done in a dark work space, the work was cumbersome and inconvenient because the worker had to carry a hand lamp while working, and as a result, there were restrictions on the worker performing the work alone.
