Description
Technical field
The utility model relates to a kind of optical cables to belong to communication equipment neck more particularly, to a kind of wind resistance power self-support cable
Domain.
Background technique
While self-support cable has all features of ordinary optical cable, when aerial laying, can avoid secondary construction, therefore more
To be applied in network construction more.The aerial laying of self-support cable inevitably will be by coastal, mountain valley etc.
More more ice-snow field bands of beam wind, are in the field extreme environment of windy or more ice and snow, to the quality of self-support cable, especially all the year round
It is that wind resistance and anti-ice-snow performance have very high requirement.Once wind resistance and anti-ice-snow performance is bad that optical signal is caused to interrupt,
Serious consequence will be caused.The side wall of traditional self-support cable is big by impact force when wind, and ice is easy to adhere on the outer wall,
The performance of wind resistance and anti-ice is poor.
Summary of the invention
The purpose of this utility model is to propose a kind of optical cable for being able to bear large wind impact, has both anti-ice-snow performance
Optical cable.
For foregoing invention purpose, the utility model adopts the following technical solution:
A kind of wind resistance power self-support cable, the non-metal reinforcement member including being located at optical cable center, around reinforcer
Several Loose tubes are set, cable cream is provided between Loose tube, a number of optical fiber is set in Loose tube, is filled out in the gap of optical fiber
It filled with fiber paste, is provided on the outside of Loose tube and inner sheath is prepared by polythene material, be nonmetallic add on the outside of inner sheath
Strong layer, is oversheath on the outside of non-metal reinforced layer, and regularly or irregularly distribution is provided with arc on the outer surface of oversheath
Connected in star is provided with super-hydrophobic coat on the outer surface of oversheath.
Preferably, the material of the Loose tube selects polybutylene terephthalate (PBT).
Preferably, the fiber paste is water uptake expansion material.
Preferably, the cable cream is water uptake expansion material.
Preferably, the width of the arc groove is arranged between 1 ~ 5mm.
Preferably, the contact angle of the super-hydrophobic coat and water is between 150 ° ~ 180 °.
The beneficial effects of the utility model are, reduce the pressure drag of cable surface, realize preferable wind resistance effect；It is super
Hydrophobic coating effectively reduces water in the attachment of cable surface, reduces cable ice coating probability.
Detailed description of the invention
Fig. 1 is the utility model schematic cross-section.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing.
As shown, a kind of wind resistance power self-support cable 100, the non-metal reinforcement member including being located at optical cable center
104, several Loose tubes 103 are set around reinforcer 104, and the material of Loose tube 103 selects polybutylene terephthalate (PBT).
Cable cream 105 is filled between Loose tube 103, cable cream 105 is water uptake expansion material.The a number of light of setting in Loose tube 103
Fibre 101, optical fiber 101 can be general single mode fiber, can also use other kinds of optical fiber according to actual needs.Loose tube
103 inside, fiber paste 102 is filled in the gap of optical fiber 101, and fiber paste 102 is water uptake expansion material.The outside of Loose tube 103
It is provided with and inner sheath 106 is prepared by polythene material, the outside of inner sheath 106 is non-metal reinforced layer 107, nonmetallic to add
The outside of strong layer 107 is oversheath 108, and regularly or irregularly to be provided with arc recessed for distribution on the outer surface of oversheath 108
Slot 109 and super-hydrophobic coat 110.It is carried out calculating the arc groove on adjustment oversheath outer surface according to the size of cable outer diameter
109 width and depth guarantees that recess width and depth are reasonable, meets aerodynamics, effectively reduce windage.Arc groove
109 effectively increase cable surface roughness, greatly reduce the pressure drag being subject to when blowing, and also allow for wind-force to the work of optical cable
Firmly reduce, to reach windproof effect.Preferable wind resistance effect may be implemented in the width setting of arc groove between 1 ~ 5mm
Fruit.
One layer of super-hydrophobic coat 110 is wrapped up on oversheath outer surface, is effectively reduced water in the attachment of cable surface, is subtracted significantly
The probability of few icing reduces the probability that optical cable damages in harsh environment so that the wind resistance anti-ice ability of optical cable greatly increases.
Preferable hydrophobic effect may be implemented between 150 ° ~ 180 ° in the contact angle of super-hydrophobic coat and water.
