Abstract
The invention discloses an armored air blowing composite optical cable which comprises a cable core (1) and a protection sleeve (2) covering the cable core (1). The cable core (1) comprises an optical fiber unit (3) and reinforcers (4) arranged around the optical fiber unit (3), at least one electric conducting wire (11) is arranged in each reinforcer (4), and helical convex grains (7) are further arranged on the periphery of the protection sleeve (2). The armored air blowing composite optical cable has the advantages that the convex grains are arranged on the surface of the optical cable, the friction between the optical cable and a mounting pipe is reduced, and mounting speed is obviously improved; the convex grains are helical, and the mounting speed is further improved; a circle of longitudinally-helical reinforcers (4) is hinged in the cable core, the shock resistance of the optical cable is greatly improved, and a YD/T769-95 environmental standard can be met; electric conducting wires are further arranged in the reinforcers of the optical cable, the power using problem of equipment can be solved, and repeated wire arrangement is avoided.
Description
Technical field
The present invention relates to a kind of armored pneumatic transmission composite cable.
Background technology
Optical cable is mainly by optical fiber (thin as the glass fiber of hair) and plastic protective sleeve pipe and plastic peel formation.Optical cable is the main delivery means of the various information networks of current information-intensive society.
The system of laying of optical cable comprises overhead type, direct burial and duct type, duct type is generally air-blowing optical cable mounting means, adopt mode that high pressure draught blows by optical cable lowering in the silicon core pipe of pre-plugged, blow cable machine by high pressure, compressed air is at a high speed blown into silicon core pipe, high pressure draught promotes sealing gland piston, the sealing gland piston that is connected to like this end of cable forms the uniform pulling force of a setting to optical cable, in this, blow cable machine hydraulic track conveying mechanism clamping optical cable is fed forward simultaneously, erection mode is very simple and practical like this, although but existing optical cable surface is all smooth, but because larger with silicon core pipe contact-making surface, rub still very large, blow very and be not easy, speed is very slow, and existing air transporting optical cable only at periphery parcel one deck steel band for shock resistance, such optical cable shock resistance is inadequate, the scope of application is very narrow, can not be for some high-intensity environment, existing optical cable only provides single broadband access, and the power supply of equipment also needs other wiring, makes circuit seem very complicated.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, and a kind of armored pneumatic transmission composite cable is provided, and solves following problem: (1) existing air transporting optical cable because and between mounting pipe, rub excessively, cause installation rate very slow; (2) existing air transporting optical cable shock resistance is good not, is difficult to use in some high-intensity environment; (3) existing optical cable can only provide light signal, too single.
The present invention is achieved through the following technical solutions: armored pneumatic transmission composite cable, the sheath that comprises cable core and parcel cable core, described cable core comprises fiber unit and is arranged on fiber unit reinforcement around, described fiber unit comprises the loose sleeve pipe of fibre ribbon and parcel fibre ribbon, described reinforcement along fiber unit outer wall centered by fiber unit axis, longitudinal extension in a spiral manner clad optical fiber unit, in reinforcement, comprise at least one fax wire, in the periphery of sheath, be also provided with spiral burr.
The cross section of described burr is triangle.
Between described loose sleeve pipe and fibre ribbon, be filled with fine cream.
In the gap of described cable core, be filled with greasy for preventing water.
Between described cable core and sheath, be provided with plastic-coated steel band.
Between described cable core and plastic-coated steel band, be provided with waterstop.
The invention has the beneficial effects as follows: the surface at optical cable arranges burr, reduced and mounting pipe between friction, installation rate is significantly improved; Burr twist, has further improved installation rate; In cable core, the longitudinal spiral reinforcement of a stranded circle, is greatly improved the shock resistance of optical cable, can meet YD/T769-95 environmental standard; In the reinforcement of this optical cable, be also provided with electric transmission line, can solve the electrical problem of equipment, avoided repeating wiring.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As shown in Figure 1 and Figure 2, armored pneumatic transmission composite cable, the sheath 2 that comprises cable core 1 and parcel cable core 1, described cable core 1 comprises fiber unit 3 and is arranged on fiber unit 3 reinforcement 4 around, described fiber unit 3 comprises the loose sleeve pipe 5 of fibre ribbon 6 and parcel fibre ribbon 6, described reinforcement 4 along fiber unit 3 outer walls centered by fiber unit 3 axis, longitudinal extension in a spiral manner clad optical fiber unit 3, in reinforcement 4, comprise at least one fax wire 11, in the periphery of sheath 2, be also provided with spiral burr 7.
The cross section of described burr 7 is triangle.
Between described loose sleeve pipe 5 and fibre ribbon 6, be filled with fine cream 10; In the gap of cable core 1, be filled with greasy for preventing water.
Between described cable core 1 and sheath 2, be provided with plastic-coated steel band 8.
Between described cable core 1 and plastic-coated steel band 8, be provided with waterstop 9.
The surface of the present embodiment is provided with burr 7, and when air-blowing is carried, and the friction between mounting pipe reduce, and transporting velocity is greatly improved, and burr 7 in the shape of a spiral, during conveying, provides a spiral power, the further like this transporting velocity of having accelerated.
One circle reinforcement 4 is set in the cable core 1 of the present embodiment, the shock resistance of optical cable is significantly improved, can be used in some relatively rugged environments; Pine sleeve pipe 5 adopts the PBT pine sleeve pipe with good anti-hydrolytic performance; Sheath 2 adopts the PE sheath with good anti-solar radiation, so this optical cable meets YD/T769-95 environmental standard.
