Abstract

The invention discloses a continuous strain section assembly type wiring method for ultrahigh-strength aluminum conductor steel supported wires. The method includes the steps: 1) calculation of the length of a strain section of a wire; 2) calculation of the manufacturing wire length; 3) utilization of strain hardware; and 4) an assembly type wiring process. By the method, wire loss and waste are effectively controlled, compression quality is guaranteed, and aloft operation is reduced. Further, the method is an accurate, efficient and safe construction method.

Description

technical field

[0001] The invention relates to an assembly type stringing method for a continuous tension section of an ultra-high-strength steel-core annealed aluminum stranded wire, which belongs to the technical field of electric energy transmission lines. Background technique

[0002] With the construction and development of the national intelligent and strong power network, the State Grid Corporation of China will intensify the construction of the power grid during the "Twelfth Five-Year Plan" period, focusing on the application of energy-saving and consumption-reducing conductors. Extra-high-strength steel-core soft aluminum stranded wire is one of the energy-saving conductors that is preferred for promotion. First, it is a new product of capacity-enhancing wire for transmission lines. Compared with ordinary wires, it has the following advantages: 1. The maximum operating temperature of the wire is increased from 80 degrees to 150 degrees, and the transmission capacity...
