The invention discloses a method for manufacturing a layer-stranded type double-sheath armored fully-dried type optical fiber composite optical cable. A fully-dried type optical unit, a layer-stranded type optical unit, an insulating layer, a shielded conductor, a filling rope and the like are stranded and then externally coated by using a thermal insulation belt; a plurality of dried water blocking objects can be added into a clearance of a cable core so as to achieve effects of rounding the cable core and blocking water; and a layer of inner sheath is extruded on the cable core, a metal armor layer is added, and then a layer of outer sheath is extruded. If a user needs a flame retardant effect, the conductor, the insulating layer, a filling material, the inner sheath and the outer sheath adopt a flame retardant material which is polyvinyl chloride (PVC) or low smoke zero halogen (LSZH). Meanwhile, the optical unit is the layer-stranded type optical unit which has a loose-sleeve fully-dried type structure; and the interior of a sleeve or the 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 the manufacture method of the two absolutely dry type Optical Fiber Composite of the sheath armouring optical cables of a kind of layer-twisted type.
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 dry type Optical Fiber Composite cable 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
In structured design process, focus on the protection that the structural shape and the light unit of power cable are pressed in consideration.Consider cable long-term work temperature, the light unit can adopt high temperature resistant fine cream, high-temperature resistant optical fiber, or takes certain separator to guarantee the stable of Optical Fiber Transmission performance.
According to the networking requirement of this cable, dry type light unit can adopt layer-twisted type structured light unit;
According to the cable laying demand, the oversheath form can adopt two sheath armouring types;
The manufacture method of the two absolutely dry type Optical Fiber Composite of the sheath armouring optical cables of the application's layer-twisted type is following:
(1) the preparation conductor adopts single copper cash as conductor, in the periphery of conductor coating conductor screen successively; Insulating barrier, insulation screen, metal screen layer; To reduce the interference of outer bound pair conductor, improve the transmission performance of conductor, three conductors are as a conductor element;
(2) preparation layer-twisted type light unit installs to some optical fiber on the pay off rack, adjusts unwrapping wire and stretches power, and unwrapping wire is stretched power at 40～100g;
(3) some optical fiber are drawn according to assigned direction, and be incorporated into plastic extruding machine, outside optical fiber, extrude and coated loose sleeve pipe, in the loose sleeve pipe of extruding, inject the dry type water-blocking material simultaneously, the injection rate of dry type water-blocking material is to send 92%～98% of cannula cavity cross section;
(4) reinforcement of processing by nonmetallic materials, it is parallel with the optical fiber that four loose sleeve pipes coat to be wire, and is positioned at layer-twisted type light unit center, to strengthen support force and tensile strength;
(5) with gasket for packing, the optical fiber and the non-metal reinforcement member of four loose sleeve pipe coatings coat waterstop and sheath outward successively, gasket for packing, and the slit that exists between the optical fiber of four loose sleeve pipe coatings and the non-metal reinforcement member is by the water blocking yarn filling;
(6) conductor element and a layer-twisted type light unit of three conductors being formed form cable core; Cable core is carried out optical fiber attenuation, surplus long the detection; The detection back that finishes is stranded and coat heat insulating belt successively, sheath, armour and oversheath through stranding; And increase the dry type water-blocking material in the cable core gap, close and block-water effect to guarantee the cable core rounding.
Wherein, wire insulation, filler and outer jacket adopt fire proofing.
Wherein, fire proofing is PVC or LSZH.
The light unit of the composite rope of being designed and developed by said method 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.
