One polyester or other materials tear rope is arranged under sheath in ethylene etc..
Inner sheath 110 is outer around one layer of high expansion water blocking tape layer 103 of the water blocking yarn for putting 3 or more or cladding, using FRP shape
At armor 104, FRP outer diameter 1.0mm, FRP armor 104 is pricked yarn using two or more and is fixed, FRP armor 104
One layer of high expansion water blocking tape layer 103 of outer cladding, while interior shield is outer according to water blocking yarn, need to control around pitch is put, to guarantee optical cable
Permeability performance.
Wrapped a certain number of waterproofing type aramid fibers form waterproofing type aramid layers 102, waterproofing type aramid layers outside water blocking tape layer 103
One layer of aramid fiber of setting weaves belt 101, width customization, 1.0 ± 0.2mm of nominal thickness outside 102.
Aramid fiber, which weaves, is arranged one layer of oversheath 112 outside belt 101, this protective cover material is related to high density polyethylene (HDPE), middle density
One polyester or other materials tear rope are arranged under sheath, can place more between aramid fiber braiding belt 101 and sheath for polyethylene etc.
Dry type water blocking yarn, to meet the infiltration requirement of optical cable total cross-section.If optical cable is whole entirely using dry type water-blocking material 108, light-weight,
It is more suitable for outdoor aerial.
Of the invention at least has following innovation:
1, structure innovation.Aerial gunshot-proof optical cable generally uses the structure of multi-layered steel-plastic composite band armouring, is protected with this
The cable core of optical cable is not damaged, but since secondary such structure contains metal component, optical cable heavier-weight, be not able to satisfy be laid in it is more
The region of thunder and lightning.The structure that selection FRP armouring and aramid fiber braiding belt 101 combine, forms the protective layer of sufficient intensity, simultaneously
Metal component is not contained in optical cable, can satisfy anti-gunshot and anti-lightning strike requirement.
2, material is innovated.Increase the protection intensity of optical cable in cable configuration using the aramid fiber ribbon of two layers of different-thickness.Its
It is that there is high intensity using aramid fiber yarn as narrow web fabric or tubing made of material knitting, thickness has 0.4
~2mm, stretch modulus are 3 times of steel wire, and 2 times of glass, use temperature range is wide.With high temperature resistant, fire protection flame retarding, weight
The advantages that amount is light, high-intensitive, high-modulus, low-shrinkage, the good mechanical properties such as shellproof, shock resistance, dielectricity is good, it is anti-in individual
The fields such as shield, bullet resistant material, which have, to be widely applied.To the impact in the bullet short time, high tenacity, high-energy absorption rate and high-elastic
The aramid fiber material of property modulus can absorb kinetic energy within the shortest time by rapid dispersion energy.
Increase the intensity that FRP armor 104 further increases optical cable, glass fiber reinforced composite plastic bar (FRP) has
The superior functions such as light weight, modulus height often substitute reinforcer 109 of the phosphating steel wire as optical cable in optic cable design, meet
Certain tensile strength, while having the function of anti-extraneous stress.When this gunshot-proof optical cable designs, shield is outer inside is arranged more circles
Shape FRP twists mode closing lay using spiral, to form one layer of armour protective layer.The further external force band such as buffering, dispersion bullet
The impact forces come, protect optical cable core not destroyed.
The effect and purpose of the present embodiment:
1), all dielectric provided in this embodiment makes somebody a mere figurehead gunshot-proof optical cable and provides new thought for the exploitation of optical cable.
2), all dielectric provided in this embodiment, which makes somebody a mere figurehead gunshot-proof optical cable, proves high-intensitive gunshot-proof optical cable, using light-duty complete
What dielectric structure can be achieved on.
3), all dielectric provided in this embodiment makes somebody a mere figurehead gunshot-proof optical cable and meets the aerial stretching used in optical cable field, seeps water
Equal full performance tests require and 107 optical cable basic test performance of optical fiber.
4), all dielectric provided in this embodiment is maked somebody a mere figurehead gunshot-proof optical cable and is also provided for other high intensity type cable manufactures
Direction.
Embodiment 2.
