Abstract
The invention discloses an optical fiber and copper wire hybrid cable production and manufacturing technology. A steel plastic composite tape is fixed on the internal wall of a PE sheath firstly, and two copper wires with insulating layers arranged along the radial direction of the steel plastic composite tape are fixed in the steel plastic composite tape; then a loose bushing of which the internal part is fully filled with optical fibers is arranged at one side of the two copper wires, and a steel wire with a sheath act as a supporting member to be arranged at the other side of the two copper wires; and finally water-resistant cable paste is filled in the gap of the internal part of the steel plastic composite tape so that the internal wall of the steel plastic composite tape is enabled to be completely supported and thus processing of an optical cable is completed. The steel plastic composite tape and the steel wire with the sheath act as the supporting structure of the PE sheath so that the optical fibers arranged in the loose bushing are ensured not to be damaged by wild animals or influenced by complex changes in weather under multi-protection of the PE sheath and the steel plastic composite tape, then stable working performance of the optical cable in rural areas can be guaranteed and thus an objective of reducing frequency of optical cable maintenance or replacement can be finally realized.
Description
Technical field
The present invention relates to fiber optic cable manufacture field, what specifically refer to optical fiber and copper cash mixes cable manufacturing process.
Background technology
In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.Most optical fiber before use must be coated by which floor operator guards, and namely the cable after coated is called as optical cable, and the protective layer of fiber outer layer and insulating barrier can prevent surrounding environment to the injury of optical fiber, Ru Shui, fire, electric shock etc.
And photoelectric mixed cable and optical cable box cable twisting cable together, namely in cable configuration, insulated electric conductor is added, light harvesting fibre, transmission of electricity copper cash are in one, because optical transport and delivery of electrical energy belong to two kinds of dissimilar transmission meanss, mutual interference can't be there is in transmitting procedure, equipment electricity consumption and signal transmission issues can be solved simultaneously, both remained the characteristic of ordinary optic fibre optical cable and the relevant criterion of low voltage power cables can also be met; And extensive use telecommunications network is built, rural area and cities and towns communication base station construction from far-off regions, the fiber entering household of Urban House community and building, safety monitoring project and other occasions needing information and electric power simultaneously to use.
But, when communication base station cable rural and that cities and towns are from far-off regions is laid, because it is with a varied topography, weather condition is changeful, and the factor such as wild animal is numerous, the useful life of photoelectric mixed cable is reduced greatly, often occur the situation of signal or power breakdown, and be limited by complicated geographical environment, the maintenance difficulty of circuit increases.
