Anti twisting steel rope is specially braided from high strength, high flexible galvanized steel wire. The braided steel strand has high flexibility, complete stability to rotation under tension force. The wire rope is lubricated for long time usage.
It can homogeneously distribute the pressure between the elementary wires. The special rope can increase efficiency during the overhead transmission line stringing work. The rope is packed in steel drum which can be installed directly on the reel winder of puller.
5.1 Tension stringing method
The tension stringing method is applicable for both transmission and distribution lines, and shall be considered the state of the art of the conductor installation methods.
This method is illustrated in Figures 6a to 6d for distribution lines and Figures 6e to 6m for transmission lines.
Using this method, the conductor is kept under tension during the stringing process to keep the conductor from contacting the Earth surface or other obstacles between towers since this will cause conductor surface damage. The tension in the conductor also allows it to pass over energized circuits, railway or major road crossings, etc. without contacting them.
For multiconductor per phase lines, the tension stringing method requires the installation of a light synthetic or metallic pilot rope into the stringing blocks. This is normally done using the slack stringing stationary reel method by either a towing vehicle or a helicopter or a drone. The pilot rope is used to pull in a heavier pulling rope, and the pulling rope is then used to pull in the conductors.
For single conductor per phase installations, the pulling rope may be installed directly with a towing vehicle or by helicopter eliminating the use of a pilot rope completely.
All the subconductors of each bundle are strung at the same time and with the same tension applied, to avoid difference sag behaviour once installed.
The first and most common method for tension stringing conductors is to use one or more tensioners, depending on the number of subconductors in a bundle, and one puller. This methodology can be named as "1 by n", where 1 means one pulling rope and n means the number of subconductors of the bundle (see Figure 6i).
In case of a large number of subconductors in a bundle, another possible stringing methodology is to provide a pulling rope for each conductor, by using one or more tensioners and one or more pullers. This methodology can be named as "n by n", where the first n means the number of pulling ropes and the second n means number of subconductors in the bundle (see Figure 6j).
Where a transmission line is to be reconductored, often the old conductor is used as a pulling rope to pull in the new conductor, and the puller machine becomes a puller-tensioner machine. This methodology is equivalent to the previous "n by n" method, where the first n means the number of old subconductors used as a pulling rope and the second n means the number of subconductors in the bundle (see Figure 6k).
An alternative method for reconductoring operations, when the mechanical strength of the old conductor is not well predictable, is to use a pulling rope as a tensioning element while recovering the old conductor, in order to keep them suspended from the ground and to minimize the tension value in the old conductor. Then the installed rope can be used as a pilot or pulling rope for the new conductor installation. This methodology can be named as "n by 1" method, where n means the number of old subconductors to be recovered and 1 means one tensioning rope to be used to keep tension in the old conductor bundle.
