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
Reach more than 60 ms/min, 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, birds peck hit first time after, will injure its puff, therefore without again
Peck the desire hit so that cable is effectively protected, and by the use in nearly 3 years forest zones, does 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 has stronger anti-side pressure and resistance to punching
Hit power.Commercially can is bought for ultra-fine steel fibre or glass fibre, 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 without coat or without covering and the optical fiber fibre core of coat, it might even be possible to ground using optical fiber waste product
Pressure, crush, filtering acquisition, reach the useless purpose utilized, reduce 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, and when not having overcoat, 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 greatly increases.In the present invention, oversheath can try one's best without using expensive
It nylon, can so cost is declined to a great extent, 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., preferable or conventional black.
The present invention has following main beneficial effect：Easily make, it is anti-peck 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 with the optical cable produced by prior art
Cable is all aerial laying, 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 using ultra-fine steel fibre, second group using glass fibre, second group using silica light
It is fine；Control group is 5#, and using the structure of embodiment 1, 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 respectively uses 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 obtain 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, uses
Ultra-fine steel fibre it is more excellent；Moreover, when oversheath is coloured, pecking for birds is 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.

Strong part is steel wire or fiberglass reinforced plastics；Then obtained polyester bundle yarn or other yarn classes with some strength will be purchased
Material is coated on outside reinforcer with 20~50mm pitch spiral windings and forms wrapping layer；
4th step：The step of making sheath：Low density polyethylene (LDPE) or medium density polyethylene or high-density polyethylene material are squeezed
Modeling is coated on outside the wrapping layer of the 3rd step formation and forms sheath, and the thickness of sheath is 0.8~2.0mm；
5th step：The step of making anti-peck layer：By sheath extruding machine, extrusion molding thickness is 1.0 outside the sheath that the 4th step is formed
The anti-of~3.0mm thickness pecks layer, it is described it is anti-peck layer by weight, anti-peck layer by what following raw material were formed：The poly- second of Midst density
Alkene or low density polyethylene (LDPE) or high density polyethylene (HDPE)：50~80 parts；The epoxy resin that the trade mark is 617 or the trade mark is 677：10~20
Part；A diameter of 10~80 μm, length/diameter ratio be 5~20 ultra-fine steel fibre or a diameter of 6.5~260 μm, length be
0.03~1mm silica optical fiber：40~60 parts；EVA hot-melt adhesive：5~10 parts；The cable jacket antioxygen of model 1010
Agent：3~5 parts；Aluminium hydroxide：15~25 parts；Paraffin：3~9 parts；Carbon black master batch：5~10 parts；
6th step：The step of making oversheath：Protected by sheath extruding machine in anti-peck that the 5th step is formed outside layer outside extrusion molding cladding
Cover material；The material of oversheath is low density polyethylene (LDPE) or medium density polyethylene or high density polyethylene (HDPE) or nylon 12；When outer shield
When the material of set is low density polyethylene (LDPE) or medium density polyethylene or high density polyethylene (HDPE), oversheath thickness is 1.0~3.0mm；
When the material of oversheath is nylon 12, oversheath thickness is 0.4~0.8mm.
