Problems solved by technology
The traditional fasteners used for fixing lines have complex structures, inconvenient operation and low construction efficiency. At the same time, the installation and positioning of lines are unstable and easy to fall off, which poses a great safety hazard. At the same time, the overall structure has poor toughness, deformation and fracture This phenomenon poses a great safety hazard to power transmission operations, and has poor corrosion resistance and high temperature resistance. The short life requires regular inspection and maintenance, which greatly increases the input cost. Therefore, the fasteners of the existing structure can no longer be used. Meet the needs of fast, accurate and stable use in the construction of existing line erection, which is an urgent need to be solved at present

Description
technical field [0001] The invention belongs to the technical field of application of power line erection accessories, and in particular relates to a fastener applied to power line erection, which is suitable for efficiently, stably and accurately fixing and limiting electric wires in power line erection, so as to ensure the erection of lines in electric power construction safety. Background technique [0002] The power grid is a whole composed of substations of various voltages and transmission and distribution lines in the power system. Change the voltage. [0003] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly. The operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. Power grid and China Southern Power Grid have 6 large-scale regional power grids across provinces, and have basically formed a complete long-dist...
