Problems solved by technology

Therefore, the current situation is: in order to meet the increasing requirements of railway signal transmission lines and railway communication lines, it is necessary to still adopt additional optical fiber communication lines to adapt, which brings about problems such as whether the space is permitted or not, high cost and low cost when erecting. Uneconomical, difficult management and maintenance, unfavorable for maintenance and other issues

Embodiment Construction

[0018] please see figure 1 and combine image 3 , indicating seven groups of digital shielded quads 8, each of which has a unit shielding layer, and different color codes are used to distinguish them, and the digital shielded quads 8 can be star-shaped quads group and / or pair group. Since the number of groups of the digital shielding four-wire group 8 can be determined as required, although seven groups are shown in this figure, they are not unique. Moreover, the general requirements for various structural arrangements of the digital shielded quad 8 have already been described in the aforementioned patent application No. 03236668.X. As a prior art, the applicant will not repeat it here. Depend on image 3 It can be seen that the outer part of the digital shielding four-wire group 8 is a polyester wrapping tape 10, the outer part of the polyester wrapping tape 10 is an embossed copper tape shielding layer 12, and the outer part of the embossed copper tape shielding layer 12 ...

Abstract

The synthesis cable is suitable to digital signal transmission and communication at railway stations, section main line, electrization railway or non electrization railway. The core of cable is composed of digital shielded four-wire group and insulated core. There are liner layer, aluminum sheath, inner sheath, armour layer, outer sheath from inner to outer in sequence outside core of cable. Characters are that an optical fiber is included inside core of cable. The fiber is arranged in vacant space among digital shielded four wire groups. Thus, optical fiber is not needed to construct all alone. Advantages are: economical efficiency, easy managing, protecting and troubleproof shooting.

Description

technical field [0001] The invention relates to a railway digital internal shielding photoelectric integrated cable, which is suitable for digital signal transmission and communication of railway stations, section trunk lines, and electrified / non-electrified lines. Background technique [0002] With the continuous development of my country's railway transportation, the demand for railway signal transmission lines and railway communication lines is also increasing. The original lines can no longer meet the needs, but erecting new lines on the original basis is limited by the erection space. , and is constrained by the erection requirements and will have adverse effects on future maintenance and overhaul. In the process of railway signal transmission, especially in the section of strongly electrified lines, the transmission of signals is always affected by electromagnetic waves, which reduces the quality of transmission and affects the normal operation of railway transportation...
