The present invention relates to an adjustable insulator strap for adjustable length insulator, and more particularly, to easily configure a distribution line in a live state, and to remove the existing insulator wire, The present invention relates to an adjustable insulator fixing strap device for fixing a lob to allow an additional insulator to be installed to add a track.

Recently, many telecommunications companies have leased distribution lines to add telecommunication lines to the bottom of low-voltage lines.

The strip poles of the distribution lines that constitute the telegraph poles are installed from the top of the poles in the order of overhead line, extra high voltage line, neutral wire, low voltage line, and communication line. It consists of vertical arrays.

When constructing an additional new line on a low-tension line installed in a conventional telegraph pole, it is impossible to mount a strap in a live state, and by extension, the rack line is additionally installed at the bottom of the existing line to extend the distribution line.

Therefore, it is necessary to install a separate rack pole, so the separation distance between the ground and the distribution line is not enough, and the wire connection is twisted from the top to the bottom. There is a risk of a safety accident. In particular, there is a problem in that the construction of low-voltage lines and communication lines to maintain the ground height when crossing the road, or to replace the pole with a high standard by using a live car in a state where extra high pressure is supplied.

In this case, separate the existing wires and insulators for the installation of the existing straps, insert the existing straps between the racks and insulators, fix the insulators using the insulator fixing pins, and fix the existing straps to the bottom of the racks. Assembling the insulator pin pin by inserting the insulator pin, the insulator is inserted between the upper strap and the lower strap to be fixed with the insulator support pin.

However, in order to install the existing straps in this way, the wire and the insulator are separated, and the two new straps are installed at the top and the bottom of the rack to construct additional new low voltage lines. As a result, the work was complicated and the additional low-voltage line was newly installed in the live state, so there was a risk of safety accidents during the operation. Therefore, when the newly-established low-voltage line was constructed, the trap could not be mounted in the live state. The rack is installed to extend the distribution lines. Therefore, when the communication line is added, the separation distance between the low-voltage line and the communication line cannot be secured, and there is a problem of replacing the electric pole due to the lack of the separation distance between the ground and the distribution line when crossing the road.
