Video tutorials on making pole cable handles

Pole pulling line on the production of video tutorials are as follows:Pole pulling line on the production of video tutorials

Pulling line connecting fixtures are generally used wedge-shaped wire clamps and ?UT?-type wire clamps. Pulling line production, stranded wire according to the length of the required calculation to determine the cut on the handle and the lower handle, and wedge-shaped wire clips on the upper handle ends and the lower handle and the suspension insulator connection end for fixed binding.

Wedge wire clip tongue and wire contact should be close, no sliding phenomenon, wire clip belly in the tail line side, installation should not damage the wire strand, wire bending part should not be obvious loose strand.

Installation must pay attention to the exposed part, do not expose the part of the damage, must be careful to complete the required installation of the pulling line, pulling the line has a certain range of requirements, if more than this range will be the failure of the pulling line, so be sure to pay attention to pulling the line of the various steps.

Pulling the wire installation matters:

1.pulling the wire form. Pulling the line according to the installation form can be divided into high pile pulling the line, ordinary pulling the line and special lots used in the brace and so on. Generally speaking, across the highway and other roads in order to know the distance to the ground and the general use of high pile wire, general lots using ordinary wire, and in special lots can not do the case of the wire can also be used in the measures of the pole to reinforce the force.

2. Discretionary worse weather conditions. 10kV and the following extruded power distribution line design technical regulations "DL/T5220-2005 of the 10.0.13 also requires" open area of distribution lines connected to the straight line poles across 10 bases, it is appropriate to install the wind pull line ". So the crowded line, the best according to the reality of a wind pressure measurement, in order to determine the installation of wind cable specification.
