Problems solved by technology

[0005] The purpose of the present invention is to provide a sub-shielded symmetrically stranded high-temperature-resistant low-noise cable and its manufacturing method to solve the problem in the prior art that ordinary communication cables are separated due to the friction of the medium molecules inside the cable. Or when affected by external force, the capacitance of the cable changes suddenly to cause separation of charges, or when the dielectric in

Abstract

The invention provides a sub-shielded symmetrical twisted high temperature resistant low noise cable, comprising: at least one pair of conductors, the conductors are covered in a fluoroplastic sheath; the outside of the conductors is covered with a first The semiconductor layer, the first fluoroplastic insulating layer, the second semiconductor layer and the sub-shielding layer; the gap between the sub-shielding layer and the fluoroplastic sheath is filled with a gelatinous substance. The manufacturing method of the present invention comprises the following steps: (i) drawing copper monofilament; (ii) copper monofilament annealing; (iii) stranding soft copper conductor; (iv) making core body; (v) making twisted pair core Body; (ⅵ) cabled. The first fluoroplastic insulating layer provided in the present invention realizes the equipotential between conductors, and the sub-shielding layer shields the conductors, which improves the anti-interference ability of the cable. The conductor adopts a symmetrical twisted connection structure, so that the cable Good pressure resistance and strong explosion-proof ability.
