In the present invention, due to pecking layer with anti-, anti-layer of pecking has special formula, and on the one hand it can be entered by extruding machine
Row extrusion molding, easy to process, speed of production is fast, and a diameter of below 25mm cable and optical cable, speed are produced on the extruding machines of φ 90
More than 60 ms/min are reached, and product qualified rate is high, because anti-peck has ultra-fine steel fibre or glass fibre or dioxy in layer
SiClx optical fiber, it has extremely strong performance of stabbing, and birds peck hitting after first time, will injure its puff, therefore without again
Peck the desire hit so that cable is effectively protected, by the use in nearly 3 years forest zones, do not have generation bad electric because birds peck again
Cable or optical cable and interrupt electric power, communication accident occur;Meanwhile, anti-layer of pecking of the invention is with stronger anti-side pressure and resistance to punching
Hit power.Ultra-fine steel fibre or glass fibre are commercially just commercially available, and for the anti-silica optical fiber pecked in layer, can
Rolled with purchasing optical fiber, crushed, filter acquisition, can not only use light guide fibrous finished product, can also used and not wrap
Layer or the optical fiber fibre core without coat or without covering and coat, it might even be possible to ground using optical fiber waste product
Pressure, crushing, filtering are obtained, and are reached the useless purpose utilized, are reduced the pollution of optical fiber producer;In addition, material and production in the present invention
Product are not related to problem of environmental pollution.
The present invention is easy to the equipment for making, need not adding costliness.In the present invention, when having overcoat, overcoat is pecked with anti-
Layer is common to be resisted pecking for birds and hits, when not having overcoat, and reinforcer resists pecking for birds and hit jointly with preventing pecking layer, makes optical cable or electricity
Cable is anti-peck hit, impact, the performance of pressure-resistant aspect is greatly increased.In the present invention, oversheath can try one's best without using expensive
Nylon, can so make cost decline to a great extent, and make the buying of user, safeguard that integrated cost is lower.Certainly, the outer shield in the present invention
Set can also use coloured sheath, such as red, yellow etc., black that is preferably or commonly using.
The present invention has following main beneficial effect:Easily make, it is anti-peck that effect is good, speed of production is fast, product qualified rate is high,
More resistant to pressure and more resistant to impact.
Applicant has made using contrast, light for the anti-unfirmly closing optical cable in the application and the optical cable produced by prior art
Cable is all to make somebody a mere figurehead to lay, and the structure for all using embodiment 1 of the invention, oversheath is black and red, and 1#-4# represents different
It is anti-peck layer formula, 1# is maximum magnitude, 2# be it is optimal implement formula, 3# is that suboptimum implements formula, and 4# is that more excellent implementation is matched somebody with somebody
Side, first group uses ultra-fine steel fibre, and second group uses glass fibre, and second group uses silica light
It is fine;Control group is 5#, uses the structure of embodiment 1, and only it does not prevent pecking layer, but the thickness of oversheath is this hair
The oversheath thickness of bright embodiment 1, which adds, to be prevented pecking thickness degree, and oversheath is red, and each sequence number is respectively used in the same forest zone in Hunan
100 kilometers, obtain following data.
From upper table, it is apparent that using the present invention, due to the anti-effect for pecking layer, really obtaining electric power, communications
Guarantee has been arrived, meanwhile, anti-peck in layer pecks best performance using the anti-of silica optical fiber, using the suboptimum of glass fibre, use
Ultra-fine steel fibre it is more excellent;Moreover, when oversheath is coloured, pecking for birds being more subject on the contrary and is hit.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that design of the invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
