Description

Bindless insulator for indirect live wire construction {BINDLESS INSULATOR FOR INDIRECT LIVE WIRE METHOD}

The present invention relates to a bindless insulator for indirect live wire construction, and more particularly, to a bindless insulator for indirect live wire construction capable of safely fixing a power line to an insulator body without winding a separate bind wire.

In general, a metal bar-shaped wangeum is installed on a pole where a distribution line for supplying electricity is installed, and an insulator made of ceramic is installed on top of the wangeum to support the distribution line installed on the pole.

A process of binding the distribution line to the insulator is performed using a bind wire so that the distribution line placed on top of the insulator is not separated.

However, when a power distribution line is coupled to an insulator using a bind, an unexpected power outage may occur due to contact between the distribution line and the gold while the bird places a twig or wire to build a house on the pole.

In addition, since it takes time and effort to remove the bind wire, there is a problem in that the efficiency of the insulator replacement work is greatly reduced and the safety of the operator is also reduced.

In particular, when the distribution line is fixed using the bind wire, since the operator approaches and performs the work, considerable care is required in handling the distribution line, resulting in severe fatigue of the operator.

Referring to Korean Utility Model Registration No. 02-0260950 as a technology using the conventional bind wire, a loop through which wires can pass is provided at the top of the insulator, so that the bind wire is wound after the distribution line is coupled to the insulator. Even if it is released, it can prevent further falling.

However, since a U-shaped ring is inserted into the through hole formed on the upper part of the insulator, a worker must approach and combine it directly. As it cannot be applied in the currently popular indirect live wire method, it can be replaced by the indirect live wire method without using bind. You need an insulator that can couple the furnace.

In addition, when the wire section is made diagonally to combine the insulator, an additional process is carried out, which takes time and budget and acts as a cause of deteriorating workability.

Therefore, the electric power industry is currently developing equipment applicable to the indirect live wire method using a live wire stick, etc., replacing the equipment suitable for the direct live wire method, in which workers perform work by directly contacting the high voltage live wire. It fits and has usefulness.
