Abstract

The invention provides a continuous connecting pipe used for connecting an aluminum alloy core all-aluminum conductor. The continuous connecting pipe is characterized in that the continuous connecting pipe comprises a continuous connecting pipe aluminum pipe 1, an aluminum alloy pressing connecting pipe 2, aluminum bushing pipes 5 and the aluminum alloy core all-aluminum conductor. The aluminum alloy core all-aluminum conductor comprises inner aluminum alloy cores 3 and outer layer all-aluminum conductors 4, and selected models of the aluminum alloy core all-aluminum conductors comprise JLHA1 and JLHA2, the aluminum alloy pressing connecting pipe 2 is connected to the butt-joint aluminum alloy cores 3 and placed in the middle of the continuous connecting pipe aluminum pipe 1, the continuous connecting pipe aluminum pipe 1 is arranged on the outer layer all-aluminum conductors 4, the aluminum bushing pipes 5 are arranged between the continuous connecting pipe aluminum pipe 1 and the outer layer all-aluminum conductors 4 and are arranged at the two ends of the continuous connecting pipe aluminum pipe 1, the continuous connecting pipe aluminum pipe 1, the aluminum alloy pressing connecting pipe 2, the aluminum bushing pipes 5 and an aluminum alloy core aluminum-type-line wire are coaxial. The continuous connecting pipe used for connecting the aluminum alloy core all-aluminum conductor has the advantages of being reasonable in structure, capable of improving material utilization rate, saving in cost, convenient to install, and capable of greatly improving working efficiency.

Description

technical field [0001] The invention relates to a metal fitting for an overhead power transmission line, which belongs to the technical field of metal fittings for an overhead power transmission line. Background technique [0002] The wire connection tube is used for the terminal connection of the overhead transmission line wire. It connects the two wires as a whole. The connection tube is directly installed with the wire. In addition to bearing all the tension of the wire, it is also used as a conductor to conduct current. It is an important fitting in the transmission line. . The conductors of overhead power lines are currently mostly made of steel-cored aluminum strands, aluminum strands, anti-corrosion steel-cored aluminum strands, aluminum-clad steel-cored aluminum strands, aluminum alloy strands, steel-cored aluminum alloy strands, hard copper wires, etc. Wire. At present, steel-cored aluminum stranded wire is still the main type of wire for high-voltage transmission...
