Abstract
The utility model discloses a central tube type dual-sheath armoring full-dry composite cable which comprises an optical unit and a conductor as well as an outer jacket for wrapping the optical unit and the conductor, wherein the outer jacket, a heat insulation belt, a filler, the optical unit and the conductor are sequentially integrated from outside to inside into a whole. The central tube type dual-sheath armoring full-dry composite cable has a low cost, is convenient for installation, and has the function of simultaneously transmitting an optical signal and an electric signal. Meanwhile, the optical unit is a central tube type optical unit, and adopts a loose sleeve type full-dry structure, namely, a dry type water stopping material is adopted in a sleeve or a cable core for realizing the function of full-section water proofing and moisture resisting.
Description
Technical field
The application relates to a kind of two sheath armouring dry type composite ropes of central tubular that have 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 utility model 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.
The utility model content
The two main utility model contents of sheath armouring dry type composite rope of the central tubular of designing and developing are 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 two sheath armouring dry type composite rope concrete structures of this central tubular are: this composite rope comprises light unit and conductor and the oversheath that coats them, is followed successively by from outside to inside: oversheath, armour, inner sheath; Heat insulating belt, filler, light unit and conductor, said conductor is coated with conductor shield from inside to outside; Insulating barrier, insulation screen, metal screen layer; 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.
Wherein: fire proofing is PVC or LSZH.

Embodiment
With reference to Fig. 1,2, the two sheath armouring dry type composite rope concrete structures of this central tubular are: this composite rope comprises light unit and conductor and the oversheath that coats them, is followed successively by from outside to inside: oversheath; Armour, inner sheath, heat insulating belt, filler; Light unit and conductor, said conductor is coated with conductor shield, insulating barrier, insulation screen from inside to outside; Metal screen layer, said smooth unit are 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.
Structure: lead after dry type light unit (central tubular), insulating barrier and the shielding and gasket for packing etc. are through stranded back outsourcing heat insulating belt; The cable core gap can increase some dry type water-blocking materials to guarantee cable core rounding and block-water effect; Extrude one deck sheath at cable core then; Add the metal armouring layer, finally extrude one deck oversheath again.If the user needs flame retardant effect, then wire insulation, filler, sheath and oversheath employing fire proofing are PVC or LSZH.
