Industrial flexible-shielding cable

Abstract

The invention discloses an industrial flexible-shielding cable, comprising a cable body; the cable body includes conductors, an insulation layer, a shielding layer and an outer sheath; a cross section of the cable body is of a circular structure; a plurality of the conductors are arranged inside the cable body; outsides of the conductors are fixedly connected by PVC (polyvinyl chloride) plastic connecting rods; one insulation layer is mounted outside the PVC plastic connecting rods; gap portions between the insulation layer and the PVC plastic connecting rods are provided with a water-blocking layer; the shielding layer wraps the insulation layer tightly in an extrusion manner; the shielding layer extrudes and wraps an armor layer, a reinforcing braid layer and a filling layer tightly and orderly from the inside to out; a plurality of drainage cores are mounted in the armor layer; a layer of the outer sheath wraps the filling layer in an extrusion manner. The cable has the advantages of reasonable structure design, good shielding property and long service life, and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to an industrial flexible shielding industrial cable. Background technique [0002] At present, with the development of science and technology, people have more and more demands on cables. Cables are a common data signal transmission equipment, which have the advantages of large communication capacity, high transmission stability and good confidentiality performance. However, the existing Some common polymers are used in the cable protective layer, which not only has a short service life, but also pollutes the environment, and the existing cables are complex and diverse due to their working environments. During the working process of the cables, some strong The electromagnetic waves interfere with it, causing the cable to be in an unstable state during transmission, causing the signal to leak to the outside, and causing great losses to the enterprise.
