Description
Technical field
The present invention relates to a kind of optical cable, specifically a kind of central tubular fire-retardant cable.
Background technology
Optical cable (optical fiber cable) be in order to meet optics, machinery or environment performance specification and manufacture,
It is by the use of one or more optical fiber being placed in cladding sheath as transmission medium and the communication that can use individually or in groups
Cable-assembly.Optical cable is mainly by optical fiber（The glass fiber of thin such as hair）Constituted with plastic protective sleeve pipe and plastic peel,
There is no the metals such as gold, silver, copper aluminium, general non-recovery value in optical cable.Optical cable is a number of optical fiber according to certain way group
The stranding heart, is surrounded by outward sheath, the also cladding outer jacket having, and is used to realize a kind of communication line of optical signal transmission.I.e.：By light
It is fine（Optical transmission carrier）The cable formed by certain technique.The basic structure of optical cable be usually by cable core, strengthen steel wire,
Several parts such as filler and sheath composition, according further to needing the also component such as waterproof layer, cushion, insulated metal wire.
Existing optical cable is generally the internal circular optical cable comprising multifiber, Loose tube filled type structure, in order to increase
Pull resistance, inside filling aramid fiber or other metals, can apply to outdoor.
Present optical cable tensile effect is general, is easily damaged in wiring, and protective capability is not enough, particularly anti-flammability
It is poor, cause optical cable using being badly damaged, cause service life shorter, it is impossible to meet present use requirement.
The content of the invention
It is an object of the invention to provide a kind of central tubular fire-retardant cable, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：

In inner sheath, inner sheath is socketed in the first fire-retardant set, and the first fire-retardant set outside is wound with bandlet, and bandlet is arranged on tension set
Interior, tension is set in waterproof jacket, and waterproof is set in the second fire-retardant set, second it is fire-retardant be set in oversheath, outward
Sheath outer layer scribbles the flame retardant paint bed of material.
As further scheme of the invention：The center reinforcemen is arranged in polyethylene jacket, and center reinforcemen is non-
Metal reinforcing fibre.
As further scheme of the invention：Tensile steel wire is provided with the tension set.
As further scheme of the invention：The oversheath is polyvinyl chloride oversheath.
As further scheme of the invention：Fire-retardant fine cream is filled with the fibre bundle.
Compared with prior art, the beneficial effects of the invention are as follows：Structure of the present invention is novel, and easy to use, fire resistance is good,
Tensile capacity is strong, and long service life meets present use requirement.
Brief description of the drawings
The structural representation of tubular type fire-retardant cable centered on Fig. 1.
In figure：The fire-retardant fine cream of 1- polyethylene jackets, 2- center reinforcemens, 3- fibre bundles, 4-, 5- inner sheaths, 6- first are fire-retardant
Set, 7- bandlets, 8- resistance bands, 9- tensile steel wires, 10- waterproof jackets, the fire-retardant sets of 11- second, 12- oversheaths, the fire-retardant paint vehicles of 13-.
Specific embodiment
