Abstract
The invention discloses a central-tube type single-sheath unarmored fully-dried type composite cable. The composite cable comprises an optical unit, a conductor and an outer sheath which coats the optical unit and the conductor. The composite cable, from the outside to the inside, is sequentially provided with the outer sheath, a thermal insulation belt, a filling material, the optical unit and the conductor, wherein the optical unit is integrated with an electric unit. The composite cable is low in cost and convenient to install and has a function of transmitting an optical signal and an electric signal at the same time. Meanwhile, the optical unit is a central-tube type optical unit which has a loose-sleeve fully-dried type structure; and the interior of a sleeve or a cable core is made of a dried type water blocking material, so that water-proof and moisture-proof effects of total cross-section are achieved.
Description
Technical field
The application relates to a kind of non-armouring dry type of central tubular list sheath 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, and 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.This invention is mainly used in 10kV and the following power distribution network thereof, and system of laying is main with direct-burried or pipeline, and its major advantage is following:
(1) realizes the effect that blocks water because of light unit total cross-section adopts the dry type material water-proof material, do not have the vertical drip problem of ointment, so can effectively protect light unit total length section to block water in section or the vertical wirings significantly at drop;
(2) fill because of no ointment in the light unit, so such Optical Fiber Composite cable has better fire resistance;
(3) because of optical fiber by bale breaking the cover in; Be bound in the tight sleeve layer unlike the same optical fiber of tight sleeve optic cable; Therefore in broad temperature range, have the little characteristics of decay, be particularly suitable for long application apart from optical branching device in intermediate pressure section line construction and the low pressure stage circuit.
Summary of the invention
The main summary of the invention of designing and developing of central tubular list sheath non-armouring dry type 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 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: sheath, non-metal reinforcement member; The pine sleeve pipe, dry type water-blocking material, optical fiber.
Wherein: insulating layer of conductor, filler and oversheath adopt fire proofing.
Wherein: 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 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; Wherein insulating layer of conductor, filler and oversheath adopt fire proofing.
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 composite rope is characterized in that: this composite rope comprises light unit and conductor and the oversheath that coats them, 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.
