Problems solved by technology
[0004] In view of the above-mentioned related technologies, the inventor believes that the positions of the existing aluminum sleeves, steel pipes and aluminum pipes all need to be manually adjusted and calibrated. For regions with cold weather, operators and workers tend to have stiff fingers, which affects the crimping efficiency

The present application relates to a hydraulic crimping method for special conductors and ground wires for power transmission lines used in severe cold environments, and relates to the field of power transmission line installation. The crimping method includes the following steps: Insert an aluminum sleeve into one end of the inner side of the crimped aluminum tube , and then insert a ground wire to be crimped into the aluminum sleeve plugged with the crimped aluminum tube, insert the other ground wire to be crimped into another aluminum sleeve; put the crimped steel pipe on the Put the cores of the ground wires to be crimped, and make the two cores of the ground wires to be crimped facing each other, and adjust the crimping steel pipe to the position to be crimped; Connect the aluminum tube and the aluminum sleeve pierced in the crimped aluminum tube so that the crimped aluminum tube is placed on the outside of another aluminum sleeve, move the aluminum sleeve and the crimped aluminum tube to the crimping position, and perform crimping; The above steps are all carried out in the automatic calibration crimping device. The application can effectively improve the efficiency of crimping ground wires in cold weather regions.
Description
Technical field [0001] The present application relates to the field of the installation of transmission lines, and more particularly to a hydraulic crimping ground dedicated pilot transmission line method for cold environments. Background technique [0002] Transmission line on cables is the most important element, power may be delivered to the ground guide the user, thereby forming the electricity network, the power balance across the supply. [0003] Overhead electrical power transmission lines in the construction process, on cables connected to the widespread adoption of hydraulic crimping manner, the first conductive ground coating-removing end wall, the core leaks out on cables, and two on cables in aluminum outer sleeve of the sleeve with the skin, and then put on the outside of two aluminum tubes sleeve; hydraulic clamp is then operated by the steel core two ground guide crimped together, and then on cables , aluminum and aluminum crimp sleeves together, can achieve two gr...
