Description
Technical field
The utility model is related to a kind of micro- cable of central tube, and in particular to a kind of dry type fire prevention micro- cable of protection against rodents central tube.
Background technology
Micro optical cable, referred to as micro- cable typically refers to the every micro optical cable product for containing 12~96 core fibres, and cable footpath is more common
Optical cable is much smaller.In the case of optical property identical, micro- cable is smaller than the conventional cable external diameter of same core number, from heavy and light.With communication
Industry is continued to develop, and requirement more and more higher of the people to optical cable be especially also increasingly harsh to considering for life secure context.
Therefore, the optical cable disabler stung and caused, service life is bitten due to laying rodent in environment for optical cable to shorten and logical
Letter is interrupted and the fire prevention of optical cable proposes requirement, farthest to ensure that the communication of optical cable is normally run；Simultaneously
Consider the convenience of construction.
At present, the multicore pencil optical cable of FTTH house wirings, generally includes tight tube fiber, aramid yarn reinforcing element, shield
Set.Due to relying on aramid yarn, manufacturing cost is high.Although prior art uses the original aramid yarn of glass fiber yarn material substitution
It is improved, price is reduced；But the feature of environmental protection, anti-flammability, fire line and reliability etc. be still difficult to it is satisfactory；And construct not
Convenient, low construction efficiency.For example, prior art CN103424829 A disclose a kind of new central tubular ADSS optical cables, bag
Outside the low-smoke halogen-free polyolefin for including optical fiber, fine cream water-blocking material, PBT Loose tubes, polyethylene inner sheath, glass fiber yarn and resistance to electric trace
Sheath；Fine cream water-blocking material is filled up completely with outside optical fiber, Loose tube is fully wrapped around by fine cream water-blocking material and optical fiber, and Loose tube is by inner sheath
In being wrapped in, glass fiber yarn is housed between inner sheath and oversheath.The invention is complete due to the space between optical fiber and pine set
The fine cream water-blocking material of filling is often difficult to wipe in work progress, while bringing pollution to environment, is brought necessarily to optical cable construction
Inconvenience and low construction efficiency；Pine set, the Flame Retardancy that inner/outer sheath is used is poor, and low cigarette effect is poor, poor reliability.
Utility model content
The purpose of this utility model is achieved through the following technical solutions, and a kind of dry type fire prevention protection against rodents central tube is micro-
Cable, including optical communication element, dry type material water-proof material, LSZH micro-pipes, interior fireprotection layer, LSZH inner sheaths, outer fireprotection layer, protection against rodents layer and
LSZH overcoats；Fireprotection layer in optical communication element and dry type material water-proof material, LSZH micro-pipe outer claddings is set with the LSZH micro-pipes,
Indulged outside interior fireprotection layer and extrude protection against rodents layer, protection against rodents layer outside bag LSZH inner sheaths, the outer fireprotection layer of LSZH inner sheaths outer cladding, outer fireprotection layer
Outer stranded LSZH overcoats.
Further, the optical communication element is optical fiber.
Further, the dry type material water-proof material is water blocking yarn.
Further, the quantity of the water blocking yarn is 1.
Further, the water blocking yarn is separated with the inwall and optical communication element of LSZH micro-pipes.
Further, 12 optical communication elements are provided with the every LSZH micro-pipes, the micro- cable of 12 core central tube most I is done
To 1.5mm, it can be used under the high occasion of waterproof requirement, 12 core central tube set external diameter is small, and lightweight feature can be in room
Interior outdoor application.
Further, the inside and outside fireprotection layer is formed by mica tape wrapping, plays double-deck fireproof effect.
Further, the LSZH inner sheaths, LSZH oversheaths are flame-retardant low-smoke halogen-free polyolefin jacket, can play bilayer
Fire-retardant purpose.
Further, the protection against rodents layer is made of glass fiber yarn or glass fiber tape, plays a part of protection against rodents.
The utility model water blocking yarn is directly placed into the micro- cable in center in bundle-shaped, instead of optical fiber in the prior art and loose jacket wall
Between whole interstitial fine cream water-blocking material filling, green non-pollution, and optical fiber, efficiency of construction need not be wiped in construction
Height, can be applied to pipeline；PBT Loose tubes are replaced using LSZH micro-pipes, the effect with fire-retardant, low cigarette, processing characteristics is simple
Characteristic；Using double-deck fireprotection layer and duplex sheath, double-layer safety effect is played, it is ensured that optical fiber fires in the long-time of big fire high temperature
Can be as far as possible injury-free for a long time under burning, so as to ensure the unimpeded of communication；In addition using protection against rodents layer, protection against rodents effect is played,
Farthest ensure that the communication of optical cable is normally run；Product uses dry type structure simultaneously, without additives such as fine cream, ointment,
It is more suitable for construction and lays to use.
To sum up, the utility model product has external diameter small, lightweight, environmental protection, fire-retardant, low cigarette, it is highly reliable and
The convenient, efficiency high of construction, the characteristics of cost is low.
