Background technology
Dual function of the optical fiber composite overhead ground wire (OPGW) because playing ground wire and communication, can effectively improve electric force pole tower
Utilization rate and be widely used in power communication.As country builds intelligent grid energetically, optical fiber composite overhead
The environment of wire routing is more and more, and laying is exactly a kind of in extremely cold ultra-low temperature surroundings.In ultralow temperature (less than -40 DEG C) environment
Under, the viscosity of optical fiber ointment increases, and Loose tube hinders the free to slide of optical fiber in contraction or optical cable stress, make optical fiber by
Power causes the increase of fiber transmission attenuation.And the optical fiber of resistance to ultralow temperature cream is to belong to special light fiber paste, price is high, greatly increases
The erection cost of optical fiber.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of optical fiber composite overhead ground wire of resistance to ultralow temperature, this
For vacant lot line in ultra-low temperature surroundings, the optical fiber in optical fiber composite overhead ground wire still has good degree of freedom, avoids optical fiber
Stress, so as to avoid influencing the optical transmission performance of optical cable.
To achieve the above object, the utility model provides following technical solution：A kind of optical fiber composite frame of resistance to ultralow temperature
Vacant lot line, including Loose tube, Loose tube is made of PBT, MODIFIED PP or makrolon material, equipped at least in the Loose tube
12 optical fiber fill dry type material water-proof material in the Loose tube between the fibers, and the outside of Loose tube is also surrounded with by heat insulating belt
The thermal insulation layer of composition, the thermal insulation layer continuously extrude one layer of aluminum pipe of covering, are twisted to wrap up the twisted wire of aluminum pipe outside aluminum pipe outside.
Preferably, dry type material water-proof material uses water blocking yarn or water-proofing powder.
Preferably, the outer diameter of Loose tube is 2.5~Ф of Ф 4.5mm.
Preferably, filling mica tape or glass tape, polyester belt in the heat insulating belt of thermal insulation layer.
Preferably, twisted metal wires use aluminum-clad steel wire or aluminium alloy wire.
Preferably, the thickness of aluminum pipe is 0.6~2.0mm.
Using above-mentioned technical proposal, the utility model has the advantages that：1. there is excellent resistance to ultralow temperature performance,
Filling dry type water-proofing powder or water blocking yarn, optical fiber still keep good degree of freedom, are not present under the low temperature environment of pole in Loose tube
Fiber transmission attenuation is had an impact, optical fiber is subject to Loose tube, heat insulating belt and the protection of aluminum pipe multilayer, protects light to the utmost
Fibre is influenced by ultra-low temperature surroundings；2. with excellent vibration resistance fatigue behaviour, one layer of aluminium protection of continuous extruded outside Loose tube
Pipe, eliminates the big weld seam for passing through whole Loose tube, so as to avoid in influence of the windy environment of extremely cold area to Loose tube；
3. with excellent electric property, the twisted metal wires of aluminum pipe and outer layer coordinate, and improve the short circuit electricity of optical cable to the utmost
Stream and lightning stroke electric property.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
Below in conjunction with the accompanying drawings, by the description of the embodiment, being described further to the utility model：
As shown in Figure 1, a kind of optical fiber composite overhead ground wire of resistance to ultralow temperature of the utility model, including Loose tube 1, Loose tube
1 is made of PBT, MODIFIED PP or makrolon material, and the external diametrical extent of Loose tube 1 is 2.5~Ф of Ф 4.5mm.In Loose tube 1
Equipped at least 12 optical fiber 2, dry type material water-proof material 3 is filled in Loose tube 1 between optical fiber 2, dry type material water-proof material 3 is used and blocked water
Yarn or water-proofing powder reduce installation cost, cost-effective.The outside of Loose tube 1 is also surrounded with the thermal insulation layer 4 being made of heat insulating belt,
Filling mica tape or glass tape, polyester belt, reduce cost in the heat insulating belt of thermal insulation layer 4.Covering one is continuously extruded outside thermal insulation layer 4
Thickness is the aluminum pipe 5 of 0.6~2.0mm layer by layer, improves the vibration resistance fatigue behaviour of Loose tube 4.It is twisted to wrap up aluminium outside aluminum pipe 5
Aluminum-clad steel wire or aluminium alloy wire, the stranded wire of aluminum pipe 5 and outer layer may be employed in the twisted metal wires 6 of pipe 5, twisted metal wires 6
Line 6 coordinates, and improves the short circuit current flow of optical cable and lightning stroke electric property to the utmost.
For the utility model in ultra-low temperature surroundings, it is resistance to abandon existing smearing for filling dry type material water-proof material 3 in Loose tube 1
The mode of low temperature ointment is greatly solved due to extremely cold influence of the weather to 2 transmission loss of optical fiber.When there is extreme low temperature
When, Loose tube 1 is interior without ointment, and the degree of freedom of optical fiber 2 is unaffected, can be in optical cable stress or contraction process, and optical fiber 2 can
It freely stretches, on 2 transmission loss of optical fiber there is no influence, ensure that power communication system is run steadily in the long term.
