In general, electric power generated from a power plant is transmitted to businesses and homes through wires or jump lines of distribution lines. Such an electric wire may be buried underground or installed in a distribution line pole such as a concrete pole. On the other hand, when the wires or jump wires are installed or wired in the distribution line poles, insulation support insulators are essentially used.

That is, the jump line is fixed to the electric pole of the distribution line by the support insulator. This support insulator is basically provided with a jump line support part to which an electric wire is fixed, the jump line support part, the insulator insulator part which supports a jump line, and the fixing part for fixing this insulator part to the electric pole of a distribution line. The support part is mainly formed of a magnetic material and has a plurality of wings spaced apart at regular intervals. Each of these wings has a shape where the support insulator is installed upward, one side of which is inclined downward or rounded toward the circumference of the wing from the support, while the other side has a horizontal or upwardly convex shape.

Accordingly, there is no problem when the jump line is installed in a manner of upward processing, but when the jump line is downwardly processed, rainwater accumulates due to the concave shape of each wing or foreign matter collects, resulting in insulation breakdown. have.

In addition, such a conventional jump line support insulator should be installed only in such a manner as to support the upward processing, that is, the jump line from the bottom, there is a problem that the workability is lowered and the compatibility is lowered.

On the other hand, even in the state in which the construction standard of the distribution line jump line has recently been extended to the downward processing method, due to the problems as described above, the situation is not adopting the full downward processing method. That is, for example, when wiring the three-phase jump line, only the A-phase jump line and the C-phase jump line were to be processed downward and the B-phase jump line was upwardly processed due to the fear of mixing between the jump lines or the ground body. In addition, there is a problem in that it is not possible to install a jump line or a banquet line in a complex pole such as a branch pole or an angular pole.

Accordingly, the present invention has been made to solve the above-described problems, an object of the present invention is to provide a jump line support insulator for the stable distribution of the jump line.

Another object of the present invention is to provide a jump line support insulator for distribution that can stably and spaced down multiple jump lines even in a complex space.

It is still another object of the present invention to provide a jumper supporting insulator for power distribution that prevents breakdown of insulation when the jumper is installed downward, safely installs a distribution line, and prevents accidents caused by a jumpline's contact. It is.
