The present invention relates to an upper pole support for distribution poles, and more specifically, to support the lower portion of the light arm is installed in the upper pole of the pole with a plurality of support bars, fixing the support means to the top of the pole by a separate support rod It consists of an upper support that is, the rigid support of the light arm to increase the bearing capacity of the high-voltage cable to support the high-voltage cable safely and firmly connected to the upper support of the distribution pole that can greatly improve the safety.

In general, electric power is transmitted from power plants to power substations by high voltage power through transmission lines such as transmission towers, and after several stages of transformation, the electric power lines can be used at each customer through the pole transformers along the distribution lines such as concrete poles. It is supplied to each area by cable,

Cables that support these high voltage cables are installed at regular intervals, and at the top of the poles, supporting plates (called "light beams") are installed so that each high voltage cable is parallel and has a long tension at unshorted intervals. The support is composed of a square tube shape and is fixedly installed on the upper part of the pole.

In the conventional construction of the electric wire cable, the electric cable is connected to the two sides of the light arm which is laid out on both sides of the upper pole in the orthogonal direction with respect to the wire direction of the electric wire cable through a suspension insulator, and a jumper wire is connected between the two suspension insulators. Connected, but the construction is made to support the jumper line upward or downward through the support insulator (Line post: pin insulator) installed on the upper surface of both sides of the light arm.

At this time, the light braking provided in the above is to enable the construction of the electric wire cable by fastening a plurality of suspension insulators and support insulators, etc. to the pole, and the light arm is arranged on both sides of the pole, and separate "U" shaped A binding hole (called a "U" type bolt) is wrapped around the pole and penetrates through the light arm, and is installed and fixed to the pole by the fastening nut.

However, the conventional light arm mounting structure as described above is simply supported on the pole by the "U" type fastener, so that when the heavy weight high-voltage cable is installed for a long time, the light binding force of the "U" type fastener is lowered and the light weight This phenomenon occurs under the deflection, a problem that the bearing capacity of the high-voltage cable is reduced.

In addition, when the weight and tension of the cable installed on the horizontally completed slab is not parallel to both sides of the slab, the slats are biased to one side or the bending occurs, which also reduces the bearing capacity of the high-voltage cable and safety problems. .

The present invention has been made to solve the above problems, installed in the upper pole of the pole is connected to the high-voltage cable is supported by the lower support lower by the lower support, the upper support is fixed to the upper end of the pole By supporting the upper portion by the sub-support, it is possible to maximize the holding capacity of the high-voltage cable can be firmly supported.

In addition, by giving a support force parallel to the finish by a plurality of support bars formed in the lower support, regardless of the weight and tension of the high-voltage cable to maintain the horizontal state of the complete state as it is always in the construction state to support the high-voltage cable more securely and firmly It is an object of the present invention to provide a distribution pole upper support that can greatly improve safety.

Means of the present invention for achieving the above object:

The upper pole of the distribution pole, which is arranged on both sides of the upper part of the pole, is fastened to each other by the U bolt and the fastening nut, and the high voltage cable is connected and supported by a pair of light brackets in which a plurality of suspension insulators are nut-tightened by aza pins. To
