Title:
METHOD FOR PRODUCING HIGH-PRECISION SPECIAL-SHAPED STRAND SMALL-DIAMETER CABLE
Document Type and Number:
WIPO Patent Application WO/2022/120905
Kind Code:
A1
Abstract:
A method for producing a high-precision special-shaped strand small-diameter cable, comprising the following steps: 1) fabricating a cable conductor; 2) extruding semi-conductive neoprene to form a conductor shielding layer; 3) extruding an ethylene-propylene rubber to form an insulating layer; 4) extruding the semi-conductive neoprene to form an insulating shielding layer; 5) extruding the semi-conductive neoprene to form a semi-conductive sheath layer; and 6) coating nanoscale semi-conductive glue to form a semi-conductive nano-coating. In the method, by means of a specific conductor machining process, an extrusion process of each functional layer and the like, the prepared cable has the feature of high precision; meanwhile, the performance thereof can satisfy laying requirements of cables for high-speed rail transit. Thus, the technical problem of improving product precision by means of a process method during production is solved.
