The present invention supports a high-voltage cable at the upper end of the pole and can easily adjust the direction of the line of the high-voltage cable, take a structure that can not approach the algae, the distribution pole that can prevent the power failure accident by the algae in advance Relates to a cable support device.

In general, the large power generated from the power plant is transmitted to each substation with high voltage power through a transmission line such as a transmission tower, and then, the substation transforms the transmitted power and is supplied to each region by wire cables for use in each customer. .

In addition, the electric power supply to general customers is supplied through electric poles. In this case, the electric wire cable in each electric pole is two-wire type and three-wire type depending on the distribution line, and the connection of these electric wire cables is connected using jumper wires. As already known.

Here, the high-voltage electricity is supplied to three-phase three-wire or three-phase four-wire, so three or four cables are connected, and they must be installed at all times in tension to prevent a short circuit accident.

Therefore, the poles are installed at regular intervals, and a support (hereinafter referred to as a "light brace") is installed at the top of the poles so that the high voltage cables are wired so as to have parallel tensions at intervals where the high voltage cables are not shorted. The supporting cable support has a square tube shape and is fixed to the upper part of the pole by a band clamp.

As shown in FIGS. 1 and 2, the conventional construction of the wire cable is performed on both sides of the light arm 102 which is rolled out to both sides of the upper end of the pole 100 in the direction orthogonal to the line direction of the wire cable 101. Construction has been made to connect and couple the wire cable 101 through the suspension insulator 103 and to connect the jumper wires 110 between the two suspension insulators 103.

Here, the light braking 102 for fastening several suspension insulators 103 to the pole 100 to enable the construction of the wire cable 101 is fixed to the pole 100 as shown in FIG. 2. It has been taken in a simple construction method to fasten and install using a separate "U" shaped binding sphere 200 that can take.

Therefore, the installation of the light wrist 102 could not be achieved quickly and easily and stably, and there were many inconveniences and difficulties in construction.

Referring to FIG. 2, the supplementary description will be made in detail.

In addition, the two ends of the penetrated with the nuts 201 to take a method of fastening each other, so that the construction is practically impossible to work alone, and the light brim 102 and the "U" ties 200 This is because there is a structural defect that is insufficient to maintain a stable installation state of the light arm 102 on the pole 100 because the interconnection structure between each other is not strong.

In particular, in order to direct the direction of the track from the upper end of the pole to the other direction, there was an inconvenience that the direction of the track should be changed by adding a separate support.

In addition, since the shape of the light arm takes a uniform square tube shape, a power failure accident occurred frequently due to providing a suitable flat space for birds to nest.

In addition, the shape of the light lump until now is mainly used having the structural form as described above, in fact, there was a problem that greatly inhibits the urban landscape.

Can be formed. Accordingly, since the cable 440 line is arranged in multiple stages, the direction of the line of the cable 440 may extend along different directions on the horizontal axis, thereby easily distributing the cable 440 line at the upper end of the pole 100. You can do it differently.

Meanwhile, as shown in FIG. 4, one end of each of the cable support rods 400 according to the present invention is inclined downward along the other end. That is, the inclined surface of the downward inclined straight line is formed, even if foreign matter occurs in the cable support rod 400, since it can be easily dropped downward, the cleanliness is maintained and the bird and the like to provide a nest Since it does not provide space for the user, it is possible to prevent electric shock caused by birds.

In addition, as shown in FIG. 5, the cable support rod 400 ′ may have a curved surface that is convexly curved upward, thereby further increasing the above effects.

In addition, the upper ends of the cable support rods 400 and 400 'shown in FIGS. 4 and 5 may be formed in a round shape, or the cable support rods 400 and 400' may be manufactured in a cylindrical shape, thereby further increasing the efficiency. have.

On the other hand, since the outer surface of the rotating body 300 and the cable support rods 400 including the fixing cap 200 is coated with an insulating material 500 such as a ceramic material, an electric shock caused by lightning or the like Gona, it is directly transmitted to the high-voltage cable 440 can prevent the occurrence of a large fire in advance.

As described above, the present invention has a multi-stage rotating body is installed to be rotated to the lower end of the fixed cap fixed to the upper end of the pole, the direction of rotation of the rotating body of the line of the high-voltage cables installed in the transverse direction from the upper end of the pole There is an effect that can be easily adjusted only by the operation.

In addition, the present invention is to produce a shape so as to incline the cable support rod, such as light braided fastening polymer insulator, to provide a space that is not suitable for birds nesting effect to prevent the power failure accident caused by birds There is.

In addition, the present invention, because the coating including an insulating material, such as a ceramic material on the outer surface of the rotating body and the cable support rod including a fixed cap, the electric shock caused by a lightning strike or a lightning strike is directly transmitted to the high-voltage cable of the large fire The occurrence can be prevented in advance.
