Abstract
The utility model discloses a digital communication line and in particular relates to a self-supporting twisted communication line used for digital communication. The self-supporting twisted communication line used for digital communication comprises conductors, insulating layers, pairs of wires, a cable core, reinforcing members, a tearing rope, and a sheath layer. A wire is formed by a conductor and an insulating layer. A pair of wires are formed by two twisted wires. The cable core is formed by N pairs of wires (N is a positive integer). The cable core and the reinforcing members are wrapped in the 8-shaped sheath layer. The tearing rope is disposed between the cable core and the sheath layer. The sheath layer uses environment-friendly low-smoke halogen-free flame-resistant material in order to decrease influence on environment. In addition, the pairs of wires use optimized design with little pitch in order to increase transmission performance of the cable. The reinforcing members use a single zinc-coated steel wire or multiple twisted thin zinc-coated steel wires so as to increase tensile strength of the digital communication line and prevent the internal conductors from being tensed to be thin in construction.
Description
Technical field
The utility model discloses a kind of digital communication line, specifically, relate to the digital communication stranded copper core of self-bearing type order wire.
Background technology
Development along with informationized society, requirement for the speed of the transmission of digital communication line and serviceability is more and more higher, the user has higher requirement to the electric property of digital communication line, owing to when laying, can be subject in the larger pulling force and residential quarter, the conference of exerting oneself causes the conductor drawing-down of digital communication line inside, affect the transmission performance of digital communication line, therefore digital communication physical property and environmental-protecting performance are proposed requirement, therefore needed a kind of transmission rate height of design, environmental protection and the high digital communication line of tensile strength badly.
Summary of the invention
The technical problem that the utility model solves provides a kind of digital communication stranded copper core of self-bearing type order wire, comprise: copper conductor 1, successively be wrapped in insulating barrier 2 on the copper conductor 1, to line 3, cable core 4, reinforcement 5, tear rope 6 and restrictive coating 7, it is characterized in that: the single line by two wrap insulate layers 2 twists consisting of line, the cable core 4 that adopts N (N is positive integer) group that line 3 is formed.Extrude one deck figure of eight restrictive coating 7 outside reinforcement 5 and the cable core 4, tear rope 6 parallel being placed between cable core 4 and the restrictive coating 7.
The diameter of described copper conductor 1 can be 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm.
Described twisting pitch to line 3 is not more than 35mm.
Described reinforcement 5 is that single zinc-coated wire or many stranded thin zinc-coated wires form.
Described restrictive coating material adopts environmental-friendly halogen-free low-smoke flame retardant material.
The described model specification of tearing rope 6 is 300D * 3.
The beneficial effects of the utility model are: adopt zinc-coated wire or the many stranded reinforcements that thin zinc-coated wire consists of, improved the tensile strength of digital communication line; The employing fine pith designs, and has improved the transmission performance of digital communication line; Place one between cable core and the restrictive coating and tear the rope constructability, restrictive coating is separated with cable core; Adopt halogen-free low-smoke flame retardant material as sheath material, reduced the impact on environment.
