Abstract
The utility model discloses a data communication cable for urban track traffic, which relates to the design and manufacture field of data communication cables. The data communication cable comprises two pairs of twisted pairs, a tape and an outer sheath, wherein the are twisted pairs are twisted in pairs and serve as cable cores, the tape is wound on the peripheries of the cable cores and the outer sheath is wrapped on the periphery of the tape. The data communication cable is characterized in that a mask tape and a bleeding off line are arranged between the tape and the outer sheath; the mask tape is a compound single-sided aluminium-plastic tape the plastic surface of which is in contact with the tape and the aluminium foil surface of which is in contact with the outer sheath; and the bleeding off line is located between the outer sheath and the aluminium foil surface of the compound single-sided aluminium-plastic tape.
Description
Technical field
The utility model relates to the design and the manufacturing field of communication cable, particularly a kind of urban track traffic communication cable.
Background technology
Along with the fast development of urban light rail, underground railway track traffic, the transmission range of its communication cable data requires far away, under the certain situation of impedance operator, requires decay low; Simultaneously, because poor working environment requires anti-interference and the security performance height.At present, communication cable according to the standard YD/T1019 of the Ministry of Posts and Telecommunications " digital communication with the horizontal paired cable of solid polyolefin insulation " or standard GB/T 18015 " digital communication with pair twist or star quad stranding multicore symmetrical cable " manufacture and design all can not satisfy above-mentioned requirements.
Summary of the invention
The object of the present invention is to provide a kind of urban track traffic communication cable, its long transmission distance, decay are low, and good in anti-interference performance, security reliability height.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of urban track traffic communication cable, comprise as the twisted-pair feeder of two pairs of pair twists of cable core, be wrapped in the band of cable core periphery, and the oversheath that is wrapped in the band periphery, it is characterized in that, be provided with mask tape and earial drainage line between described band and the oversheath; Described mask tape is the single face aluminium-plastic tape, and its plastic cover contacts described band, its aluminium foil surface contact oversheath; Described earial drainage line is between the aluminium foil surface of described oversheath and described single face aluminium-plastic tape.
Further improvement of the utility model and characteristics are:
Described twisted-pair feeder adopts single copper conductor, and its diameter is 0.81mm;
Described twisted-pair feeder adopts the LSOH anti-flaming polyethylene insulation;
Described oversheath adopts the LSOH anti-flaming polyethylene to make;
Described band is the polyester band;
Described earial drainage line is single copper conductor or multiply copper conductor.
In the utility model, its twisted-pair feeder adopts single copper conductor, its diameter is 0.81mm, greater than according to the greatest measure 0.6mm of the standard YD/T1019 of the Ministry of Posts and Telecommunications " digital communication with the horizontal paired cable of solid polyolefin insulation " regulation and standard GB/T 18015 " digital communication with pair twist or star quad stranding multicore symmetrical cable " regulation greatest measure 0.8mm, can satisfy ampacity greatly, the requirement of long transmission distance; Be provided with mask tape and earial drainage line between its band and the oversheath, described mask tape is the single face aluminium-plastic tape, its plastic cover contacts described band, its aluminium foil surface contact oversheath, described earial drainage line is between the aluminium foil surface of described oversheath and described single face aluminium-plastic tape, and transmission bandwidth can reach 100MHz; Described oversheath adopts the LSOH anti-flaming polyethylene to make, and twisted-pair feeder adopts the LSOH anti-flaming polyethylene insulation in it, utilizes two-layer LSOH anti-flaming polyethylene to insulate with fire-retardant, therefore, and the security reliability height.
Description of drawings
Fig. 1 is a kind of urban track traffic communication cable of the present utility model;
Among the figure: 1 is twisted-pair feeder; 2 is band; 3 is the mask tape; 4 is oversheath; 5 is the earial drainage line.
Embodiment
With reference to Fig. 1, cable core is the twisted-pair feeder 1 of two pairs of pair twists, and band 2 is wrapped in the cable core periphery, and band is the polyester band.Band twines mask tape 3 outward, and mask tape 3 is the single face aluminium-plastic tape, its plastic cover contact band, and its aluminium foil surface contact earial drainage line 5, earial drainage line 5 is single copper conductor or multiply copper conductor.
The single line of twisted-pair feeder 1 adopts the LSOH anti-flaming polyethylene insulation, and to adopt single copper conductor, its diameter be 0.81mm; Oversheath parcel single face aluminium-plastic tape and earial drainage line adopt the LSOH anti-flaming polyethylene to make.
The urban track traffic of this example is applicable to light rail, underground railway track traffic with communication cable, and its characteristic impedance is 100 ohm, and bandwidth is 100MHz; This enforcement is adopted two-layer fire-retardant, even under the situation of fire, also can guarantee the transmission of data-signal, has very high security reliability.
