Embodiment 1
[0126] Embodiment 1: A method of butt jointing aluminum-embedded crimping of 19 stranded steel strands of overhead conductors, the method includes a butt-joint aluminum-embedded crimping structure, the structure includes a steel pipe 1 and an aluminum alloy pipe 2, and the aluminum alloy pipe 2 is embedded in the steel pipe 1 19 stranded steel strands 3 are wrapped in two butted round wire concentric stranded overhead conductors, and the steel pipe 1 is crimped so that the aluminum alloy tube 2 closely fits the round wire concentric stranded overhead conductors 19 stranded steel strands 3 to form a steel core connection Pipe, steel pipe 1 and aluminum alloy pipe 2 have the same length and are two pitches of steel core strands, the method includes the following steps:
[0127] 1) Embedding the aluminum alloy tube into the steel tube;
[0128] 2) Insert the 19 stranded steel strands of the two butt-connected round wire concentric stranded overhead conductors from both ends of th...
