Background technique

The uneven distribution of electricity in my country requires long-distance power transmission. In order to reduce losses and improve power transmission efficiency, more and more UHV and EHV power transmissions are used. The diameters of corresponding transmission lines and ground wires are also increasing, and their weight is also increasing Very large, split wires are generally composed of 2-4 wires with smaller cross-sections for each phase wire, and the distance between the sub-wires is 0.2-0.5 meters, which can play the role of increasing the diameter of the wires, which is larger than the same total cross-section The wire is not easy to generate corona, and the power transmission capacity is higher, so the split wire has been widely used at present. When replacing the single-piece insulator in the insulator string with live electricity, in order to ensure the safe distance of live work, the transmission line needs to be lifted for a certain distance. Since there is no suitable lifting tool, maintenance personnel need to pull or lift it, which is laborious and time-consuming, and there are potential safety hazards . Therefore, it is necessary to provide a split wire lifter for power transmission line operation.
