Abstract
A central-tube type single-sheath unarmored full dry-type self-supporting composite cable includes an optical unit, conductors, and an outer jacket wrapping the optical unit and the conductors, wherein a steel wire plumb line and an outer sheath of the steel wire plumb line are arranged on one side of the outer jacket, the outer jacket and the outer sheath are integrated through a harness arranged therebetween, the cable part of the composite cable includes the outer jacket, a heat-insulating band, fillers, the optical unit and the conductors which are sequentially arranged from outside to inside, and the optical unit is integrated with an electrical unit. The composite cable has the advantages of low cost, convenience in installation and the function of simultaneous optical and electrical signal transmission; and the optical unit is a central-tube type optical unit, and adopts a loose tube full dry-type structure, that is, dry-type water-resisting materials are used in a tube or a cable core for full cross-sectional waterproofness and moisture resistance.
Description
Technical field
The application relates to a kind of non-armouring dry type of central tubular list sheath self-supporting composite rope that has light signal and signal of telecommunication transfer function simultaneously.
Background technology
Along with national intelligent grid strategy requirements on Construction, national grid will carry out the intelligent grid construction in China.Intelligent grid is to be that the strong rack of key rack, electric network coordination at different levels development is the basis with extra-high voltage grid; With communication information platform is support; Have informationization, automation, interactive characteristic; The generating, transmission of electricity, power transformation, distribution, electricity consumption and the scheduling six big links that comprise electric power system; Cover all electric pressures, realize that many nets of " flow of power, information flow, Business Stream " merge, have the modern power network of strong reliable, economical and efficient, clean environment firendly, transparent opening and friendly interactive intension.Medium and high pressure section cable in the market; Utilize OPGW or ADSS and existing electrical lead to constitute the notion that many nets merge, and at middle pressure and low pressure stage, when promptly perhaps the user inserts in the metropolitan area network; Consider the city look and feel construction requirements; The cable system of laying is often underground by transferring on the road, and just pipeline and direct-buried mode become more general, the optical fiber that therefore will transmit information and electrical lead permeate bar Optical Fiber Composite cable will become intelligent grid build in the main force of middle pressure and low pressure stage.
The light unit adopts loose sleeve pipe dry type structure in the non-armouring dry type of the central tubular list sheath composite rope newly developed; Just the interior perhaps cable core of sleeve pipe adopts the dry type material water-proof material to realize the effect of total cross-section waterproof retaining tide; It adopts, and self-bearing type is built on stilts to be laid, and a kind of brand-new access way is provided in the cable construction.
Summary of the invention
The main summary of the invention of designing and developing of the non-armouring dry type of central tubular list sheath self-supporting composite rope is that the light unit has adopted the dry type structure; Just in loose sleeve pipe and the cable core gap adopt the dry type material water-proof material to realize that total cross-section blocks water, the overall optical unit is nonmetal full dielectric structure.Because whole optical fiber composite cable has adopted outstanding raw material of performance and relatively more suitable structure; Therefore; Not only the light unit has the characteristics of heat insulation preferably, resistance to compression and tension, and whole cable has electric property and optical property preferably, satisfies the demand that intelligent grid is built fully.
The non-armouring dry type of this central tubular list sheath composite rope concrete structure is: this composite rope comprises light unit and conductor and the oversheath that coats them, is provided with steel wire messenger wire and outer jacket thereof in a side of oversheath, is provided with suspender belt between oversheath and the outer jacket and fuses; Composite rope cable part is followed successively by from outside to inside: oversheath, heat insulating belt, filler; Light unit and conductor, said conductor has insulating barrier outward, and said smooth unit is central tubular light unit; This central tubular light unit is followed successively by from outside to inside: light unit sheath, non-metal reinforcement member, loose sleeve pipe; The dry type water-blocking material, optical fiber; Above-mentioned insulating layer of conductor, filler and oversheath adopt fire proofing, and fire proofing is PVC or LSZH.

Embodiment
With reference to Fig. 1,2, this composite rope comprises light unit and conductor and the oversheath that coats them, is provided with steel wire messenger wire and outer jacket thereof in a side of oversheath; Be provided with suspender belt between oversheath and the outer jacket and fuse, composite rope cable part is followed successively by from outside to inside: oversheath, heat insulating belt; Filler, light unit and conductor, said conductor has insulating barrier outward; Said smooth unit is central tubular light unit, and this central tubular light unit is followed successively by from outside to inside: light unit sheath, non-metal reinforcement member; The pine sleeve pipe, dry type water-blocking material, optical fiber; Above-mentioned insulating layer of conductor, filler and oversheath adopt fire proofing, and fire proofing is PVC or LSZH.
Structure: lead after dry type light unit (central tubular), insulating barrier coat and gasket for packing etc. are through stranded back outsourcing heat insulating belt, and the cable core gap can increase some dry type water-blocking materials to guarantee cable core rounding and block-water effect, extrudes one deck oversheath at last again.If the user needs flame retardant effect, then wire insulation, filler and outer jacket employing fire proofing are PVC or LSZH.
Claims (3)
1. the non-armouring dry type of central tubular list sheath self-supporting composite rope is characterized in that: this composite rope comprises light unit and conductor and the oversheath that coats them, is provided with steel wire messenger wire and outer jacket thereof in a side of oversheath; Be provided with suspender belt between oversheath and the outer jacket and fuse, composite rope cable part is followed successively by from outside to inside: oversheath, heat insulating belt; Filler, light unit and conductor, said conductor has insulating barrier outward; Said smooth unit is central tubular light unit, and this central tubular light unit is followed successively by from outside to inside: light unit sheath, non-metal reinforcement member; The pine sleeve pipe, dry type water-blocking material, optical fiber.
