High-strength digital communication cable

Abstract

The invention belongs to the technical field of communication cables, and relates to a high-strength digital communication cable. Two leads formed by wrapping solid copper conductors with polyethylene insulation layers are stranded to form a core wire group, 1-8 pairs of core wire groups are stranded and then lapped with wrapping tape layers to form a cable core with a circular cross section, gaps among the stranded core wire groups and the wrapping tape layers are filled with fillers, and a longitudinal wrapping layer, a braided shielding layer, an inner protective layer, an armor layer and an outer protective layer sequentially wrap the outside of the cable core from inside to outside to form the high-strength digital communication cable. Aramid fibers serve as the fillers, the 'S'-shaped steel screw interlocking armor layer is used, the composite outer protective layer comprises a polyurethane elastomer sheath, talcum powder and an irradiation crosslinking polyvinyl chloride sheath, so that the cable has high tensile strength, compressive capacity and good softening property, and high strength of the digital communication cable is realized. The high-strength digital communication cable is applicable to network cabling of protective environments which are easily trod and squeezed and free from pipelines, slots and the like.

Description

technical field [0001] The invention belongs to the technical field of communication cables, in particular to a high-strength digital communication cable. Background technique [0002] With the rapid development of modern communications, the use of digital communication cables is becoming more and more complex. For example, under indoor carpets, wall trenches, and outdoor harsh environments, it is inevitable to trample, squeeze, and pull cables. Stretching, impact and dragging during construction, etc. This external influence will damage the core wire and core wire structure inside the cable, and then affect the data transmission capacity. This requires the data cable to have better compression and tension resistance. Strength, and better flexibility, but the current digital communication cables can not meet the above requirements. There is a need for a high strength digital communications cable. Contents of the invention [0003] The purpose of the present invention is ...
