Description

Aerial branching device equipped with light emitting diodes {SERVICE WIRE AIR BRANCHING DEVICE WITH LIGHT EMITTING DIODE}

The present invention relates to a drop-in aerial branching device equipped with a light emitting diode, and more particularly, branching a new incoming wire in the air from an existing wire to smoothly supply electricity to places where it is difficult to install an electric pole, such as an intersection or a narrow alley. It relates to a drop-in levitator equipped with a usable light emitting diode.

In general, distribution lines are mainly composed of multi-levels on the circumferential surface of electric poles, and such distribution lines have recently been leased from telecommunication companies and installed with electric poles by adding communication lines to the lower end of low voltage distribution lines.

That is, the overhead branch wire, the extra-high voltage wire, the neutral wire, the low voltage wire, and the communication wire are sequentially installed from the top on the circumferential surface of the pole to constitute the distribution line.

However, in the process of installing additional electric poles in response to the increase in power demand, it is difficult to maintain a sufficient safe distance between overhead branch lines, low-voltage lines, etc., and there is a risk of safety accidents.

Therefore, in order to solve this problem, conventionally, an aerial branching device for a lead-in line is used, which is connected to a lead-in wire by branching the wire by coupling to the wire trunk.

The conventional aerial divergence device connects a low-voltage line to a low-pressure human insulator installed on a low-pressure rack body, or connects a branched low-voltage line using a separate PVC insulator.

However, since this construction method is not according to the prescribed construction method, it does not guarantee the safety of the workers during construction, and the dip of the low voltage cable occurs greatly after construction, which causes the problem of securing the ground height of the low voltage cable and impairing the aesthetics of the city. have.

In addition, there is a high possibility that wind pressure due to wind takes a lot in maintenance and loss of insulation due to contact with external objects, for example, vinyl, tree branches, etc.

In this case, there are concerns about the safety of the general public and workers.
