Abstract

The invention relates to a construction method for strung wire without spanning frame without power outage, and relates to the technical field of power transmission line construction technology. The construction method without spanning frame and without power failure according to the present invention includes locating the ground anchor position according to the construction plan and burying the ground anchor on the side of the spanned power line, deploying the load-bearing cable according to the construction requirements through the circulating rope and pulling the load-bearing cable through the tension machine. Stretch to the preset tension. When the stretching is completed, use the tractor to pull the circulating rope to spread the trawl rope. Determine the size of the insulation net according to the width of the spanned power line and the angle between the spanned power line and the new wire, and then connect the insulation net to the trawl rope. And it is pulled by the tractor to the predetermined position, and the new wire is stretched to the iron tower through the pay-off block through the circulating rope. Compared with the conventional construction method, no temporary beams need to be installed, the construction procedure is simple, and the environmental damage is reduced. There is no need for power outages when crossing lines, avoiding economic losses caused by power outages, and improving the efficiency of wiring construction.

Description

technical field [0001] The invention relates to the technical field of power transmission line construction technology, in particular to a construction method for strung lines without spanning frames and without power failure. Background technique [0002] With the vigorous development of the electric power industry, the path of the newly built overhead transmission line is more complex and the crossover occurs frequently. It is inevitable to need to cross over the live line. Crossing construction without power failure has become the main trend to solve the above difficulties in crossing construction. The application of the construction method of crossing live lines without crossing frames and without power failure can simplify the crossing construction procedures, reduce the use of tools and equipment, reduce cumbersome power outage procedures, and can reduce the number of construction personnel and save costs caused by construction and power outages. [0003] The construc...
