Flexible through ground wire and production process thereof

The invention belongs to the technical field of cable production and processing technologies, and particularly relates to a flexible through ground wire and a production technology thereof. The flexible through ground wire is prepared from circular strand units, or is prepared from a wire core formed by twisting a plurality of circular strand units and a high-conductivity high-temperature-resistant composite material wrapping the wire core. The circular single wire units or the circular folded wire units are formed by twisting a plurality of anti-corrosion copper single wires. The anti-corrosion copper single wire is prepared from a copper single wire and a high-conductivity anti-corrosion coating coated on the periphery of the copper single wire. According to the process disclosed by the invention, the flexible through ground wire is prepared by adopting a mode of firstly coating the high-conductivity anti-corrosion coating and then twisting, and the working procedures of heating, extrusion molding, cooling
