The present invention relates to an insulator-mounted power line fixing device, and more particularly, by providing a structure capable of mounting and disassembling by using a tool for non-contact of an operator, the time required for mounting and installation is reduced to increase work efficiency. In addition, it relates to an insulator-mounted power line fixing device that prevents safety accidents and provides reliability of fixing power lines and convenience of disassembling power lines.

In general, a wangeum, which is an iron bar, is installed on the pole of a distribution line supplying electricity, and an insulator corresponding to a fraudulent insulator is installed on the wangeum to support the power line on the pole, and the separation of the power line on the insulator is installed. In order to prevent it, binds are used to tie the power lines to the insulator.

However, when the tide puts a tree branch or wire on the pole to build a house on the pole, the power line installed on the pole fails to block contact with the power line, resulting in an unexpected power outage, and the cover of the bind is damaged. There was a problem that caused the contact between the and Wankeum.

In addition, since the bind requires a lot of effort and time at the time of dismantling, it has a problem that not only significantly lowers the efficiency of the replacement work of the bind or insulator, but also impairs the safety of the worker.

In order to improve this problem, the Korean Utility Model No. 20-1999-0038816, "Bindless line post cover for power outage prevention," has been proposed. This is a combination of a plurality of fastening means being fastened to the fastener, but at both ends in the longitudinal direction.

It is composed of a connecting pipe formed with a third connector.

However, such a prior art requires considerable attention in handling the power line, due to the structural characteristic of being fixed to the insulator only when the power line is inevitably inserted first, and there are many risks in the replacement and installation of the bindless line post cover. As a result, it takes a lot of time and effort to work related to the power line, and has a problem that greatly impairs the safety of workers.

In order to solve the problems of the prior art as described above, the present invention provides a structure that can be mounted and disassembled by using a tool for preventing the power line from being disconnected and not contacting the operator, so that the time required for installation and installation It not only improves work efficiency by reducing the number of components, but also greatly helps to prevent safety accidents, and by inserting and fixing the power line first while being fixed to the insulator, not only makes it easier to handle the power line, but also works on the power line.
