Description
The application is that name is called: have the self-support cable of identification strip, the applying date is: on 01 26th, 2014, application number be: the divisional application of the patent of invention of 201410036276.5.
Technical field
The present invention relates to technical field of cables, especially relate to a kind of lock coloured light cable.
Background technology
Self-support cable is mostly used in built on stilts laying, load function admirable due to himself, therefore need not be supported achieving that laying of cable by extra steel strand wires, it is common that cable is fixed on the fixture at shaft tower place, and is freely place between adjacent shaft tower.But, along with developing rapidly of communication industry, the number of cables between shaft tower sharply increases, and owing to being not easy to distinguish, therefore brings great trouble to maintenance.For this, carry out substantial amounts of research both at home and abroad, notification number is CN202196211U, name is called the surface 8-shaped self-support aerial cable with vitta, including optical cable core and oversheath, optical fiber and the Loose tube of fine cream is set in having in cable core, center reinforcement, the supporting part being made up of steel wire and sheath thereof it is provided with in the side of oversheath, it is provided with suspender belt between oversheath with steel wire sheath to be connected, the cross section of cable is 8-shaped, it is provided with one or several color bar at oversheath and steel wire jacket surface, it can distinguish different optical cable according to the color of the vitta on its surface and quantity, facilitate the maintenance of optical cable, ensure the normal use of optical cable.Notification number is the optical fiber that CN202256824U, name are called that the optical cable of tape identification extends in the same direction with sheath in including sheath and being coated on described sheath, the surface of sheath extends along direction and is formed with mark vitta, can pass through to identify vitta in numerous optical cables, very easily find required optical cable, easy to identify, it is simple to repairing, maintenance；And optical cable can be identified by two or more mark vitta combinations and the width of vitta, thickness and position relationship each other, more optical cable can be identified.Above-mentioned document do discloses the identification strip of optical cable identification, but, there is following common defect: (1) adopts braided wires as the reinforcement of messenger section to realize self-supporting, although having reached the function of bigger holding capacity, but, sheath outside braided wires is extremely rough, and the sheath performance of optical cable is extremely undesirable；Accomplish smooth, the thickness of sheath must be greatly increased, which increase weight and the cost of optical cable, make the span of optical cable shorten.(2) according in the defect of above-mentioned (1), the thickness of the identification strip on messenger wire sheath is difficult to control, therefore the quality extremely unstable of product, and speed of production is fairly slow.Additionally, the phenomenon that identification strip ubiquity color of the prior art is unstable, in south east asia, optical cable, after built on stilts laying 1 year, occurs in that the phenomenon that identification strip fades to some extent, have impact on the accurate use of mark.
Summary of the invention
For solving the problems referred to above, the present invention discloses a kind of a kind of lock coloured light cable, it can make optical cable appearance more rounding width and thickness smooth, identification strip to be controlled more accurately, outside dimension less from the material consumption of load reinforcement messenger wire sheath, optical cable is less in optical cable, the speed of production of optical cable faster, identification strip more stable；It realizes by the following technical solutions.

Applicant has carried out contrast test for embodiment 1 to embodiment 4 and the optical cable with identification strip of the prior art, and result of the test is as follows.
From upper table it is apparent that adopt the identification strip of inventive formulation and/or mark band to have excellent colour stability and salt fog resistance and heat aging property.
Certainly, the one lock coloured light cable described in any of the above-described embodiment, it is characterised in that described mark band can be the raw material identical with identification strip.
The invention process example 1 to embodiment 4, speed of production has all reached 80 ms/min, the phenomenon of bad order does not occur；And in prior art, produce the speed of this optical cable less than 25 ms/min and bad order rate more than 18%；Compared with prior art, owing to the core number of optical cable is different, therefore the external diameter of optical cable is also different, and with comparing of core number, the total height of optical cable reduces 15% 30%, the overall weight of optical cable alleviates 11% 18%.
In the present invention, owing to have employed non-stranded single reinforcing element, therefore, the messenger wire sheath of optical cable when do yesterday relatively thin, messenger wire sheath can also accomplish smooth rounding；THICKNESS CONTROL is more convenient, product qualified rate is high and speed of production is fast；Owing to the wall thickness of messenger wire sheath can be relatively thin, therefore, the material consumption of messenger wire sheath can efficiently reduce, therefore can be effectively reduced the deadweight of optical cable, can effectively increase the span of fiber cable laying.Owing to identification strip and/or mark band have employed special formula, therefore, the molding of identification strip is more convenient, and color stability is higher.
Therefore, the present invention has following main beneficial effect: messenger wire covering thickness control more convenient, the more smooth rounding of messenger wire sheath, production speed faster, qualification rate higher；Optical cable deadweight span lighter, that be suitable for is longer, and the color of identification strip is more stable.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that the design of the present invention can be implemented to use by other various forms, and they also fall within protection scope of the present invention.
