[0002] With the development of electrified railways in my country, the performance requirements for electrified railway contact network components are becoming increasingly higher.

[0003] The existing pre-twisted armored sheath wire has basically solved the problem of wire protection for overpasses and tunnel entrances. However, due to the limitations of production technology and transportation conditions, it is impossible to process the pre-twisted armored sheath wire into an infinite length. The molding length of each set of products generally does not exceed 5 meters. Therefore, there is a breakpoint at the adjacent point of two adjacent sets of pre-twisted armored sheath wires, which is a weak point for wire protection. In order to solve the above problem, a pre-twisted armored sheath wire connection joint is proposed. Utility Model Content
