The present invention relates to a cable cradle of a line post insulator for transmission and distribution, and more particularly, it is possible to mitigate the up and down vibration of the transmission and distribution cable while preventing the dropping and falling of the transmission and distribution cable fixed to the line post insulator installed on the pole or transmission tower. It's about the cradle of the linepost insulator.

In general, the transmission and distribution cables are insulated and fixed in a state in which a line post insulator (LP insulator) is installed through a support member such as wrought iron on the upper side of the pole and the transmission and distribution tower.

In this case, the transmission and distribution cable is mainly used to fix the winding wire to the body of the line post insulator. The bending wire is made of the same material as the transmission and distribution cable, and mainly aluminum or copper wire is used.

The bending wire has a function of preventing the transmission and distribution cable from being separated from the line post insulator by winding the transmission and distribution cable.

In the case of the conventional binding method using the bending wire, due to the characteristics of the cable installed in the high air, the weather, wind, snow, rain and other climatic influences are often installed under conditions where vibration or amplitude is likely to occur.

Therefore, when the transmission and distribution cable vibrates by the wind, the winding state of the bending wire is gradually released. At this time, the amount of unwinding of the winding state is very small, but the space charge is accumulated between the minute gaps generated here. As a result, spark occurs between the transmission and distribution cable and the bending wire, and as a result, the transmission and distribution cable is disconnected by the spark.

In addition, if this phenomenon continues, there is a problem that the bending wire is finally released and the cable is separated from the line post insulator and falls to the ground.

The present invention has been made to improve the above problems, and an object thereof is to provide a cradle of a line post insulator which can securely secure the cable to prevent the transmission and distribution cable from falling off the line post insulator and falling to the ground. have.
