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. The core wire group is made of 2 solid copper conductors covered with polyethylene insulation layer, and 1 to 8 pairs of core wire groups are twisted and then wrapped with a tape layer to form a circular cross-section cable core. Fill the gap between the stranded core wire group and the cladding layer with fillers, outside the cable core, cover the longitudinal cladding layer, braided shielding layer, inner sheath, armor layer and outer sheath in sequence from the inside to the outside. Layers make up high-strength digital communication cables. The present invention uses aramid fiber as filler, uses "S" shaped steel spiral interlocking armored armor layer, and the outer sheath is composed of polyurethane elastomer sheath + talc powder + radiation cross-linked polyvinyl chloride sheath The composite outer sheath makes the cable have higher tensile and compressive capabilities and better flexibility, and realizes the high-strength performance of digital communication cables. The invention is suitable for network wiring that is easy to be trampled on, squeezed, and has no protective environment such as pipes and wire slots.

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 ...
