Abstract
The utility model belongs to the field of communication cables and relates to a field service light high-strength digital communication flexible cable. Two leads are twisted into a twine, and a plurality of twines and several tensile ropes are twisted to form a cable core. The periphery of the cable core is sequentially coated by a belting layer, a shielding layer and a jacket layer from inside to outside, wherein the shielding layer comprises a double-face aluminum foil layer, an electric drainage wire and a copper wire weaving layer which are repeatedly coated; conductors of the leads are thin copper wires, and insulating layers of the leads are made of crosslinked polyethylene or polypropylene insulating materials; the tensile ropes are rope insulating layers made of the crosslinked polyethylene or polypropylene coated by aramid fibers; and the jacket layer is made of modified polyurethane jacket materials. The field service light-weight high-strength digital communication flexible cable improves the tensile strength and properties of abrasion resistance, flexibility, environmental protection, and the like, lightens the weight, prolongs the service life, has good shielding performance, can meet the requirement on light weight and weather resistance and is suitable for the digital communication of field moving sites.
Description
Technical field
The utility model belongs to field of telecommunications cables, and is particularly a kind of open-air with light high-intensity digital communication flexible cable.
Background technology
Because field cable, environment for use is comparatively abominable, and is dilatory frequent during use, and common field cable anti-opened, tension, wear-resisting and weather-proof scarce capacity, often causes cable life shorter.In addition, there are many producers to increase tension, the tensile strength that steel wire is used for improving cable in the cable in the open air at present.But when increasing steel wire raising tension tensile strength, certainly will increase cable weight, influence the softness of cable, cable be used impact.
The utility model content
The purpose of this utility model is in order to solve problems such as existing field cable tension tensile strength deficiency, flexibility difference, provide a kind of open-air with light high-intensity digital communication flexible cable, it is characterized in that, conductor 1 surperficial coated wire insulating barrier 2 constitutes lead, article two, lead is twisted into the line group, by 1～25 line group and 1～8 tension rope are formed cable conductor after stranded, the cable conductor periphery coats with belting layer 5, screen and restrictive coating 9 from inside to outside successively; Described screen is made of two-sided aluminium foil layer 7, drain wire 6 and the copper wire braid 8 of overlapping coating, two-sided aluminium foil layer 7 overlapping belting layer 5 peripheries that are coated on, copper wire braid 8 is woven in two-sided aluminium foil layer 7 peripheries, perhaps do not have the copper wire braid, between two-sided aluminium foil layer 7 and belting layer 5, vertically place a drain wire 6.
Described conductor 1 is that diameter is bare copper wire or the tinned wird of 0.32～1.0mm.
The material of described wire insulation 2 is crosslinked polyethylene or polypropylene insulation material.
Described twisting pitch to two leads of line group is 6～50mm.
Described tension rope is the aramid fiber silk 3 outer rope insulating barriers 4 that coat, and rope is crosslinked polyethylene or polypropylene with the material of insulating barrier 4.
