One floor height expansion water strip layer 103 of outer cladding, while interior shield is outer according to water blocking yarn, need to control around pitch is put, to ensure 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 is set to weave belt 101, width customization, 1.0 ± 0.2mm of nominal thickness outside 102.
One layer of oversheath 112 is set outside aramid fiber braiding belt 101, this protective cover material is related to high density polyethylene (HDPE), Midst density
Polyethylene etc., one polyester or other materials tear rope are set under sheath, more can be placed between aramid fiber braiding belt 101 and sheath
Dry type water blocking yarn, to meet the infiltration requirement of optical cable total cross-section.If optical cable integrally uses dry type water-blocking material 108 entirely, light-weight, its
It is more suitable for outdoor aerial.
The present invention's at least has following innovation：
1st, 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 a structure contains metal ingredient, optical cable heavier-weight, it is impossible to satisfaction is laid in more
The region of thunder and lightning.The structure that selection FRP armourings and aramid fiber braiding belt 101 are combined, forms the protective layer of sufficient intensity, at the same time
Metal ingredient is not contained in optical cable, can meet anti-gunshot and anti-lightning strike requirement.
2nd, material is innovated.The protection intensity of optical cable is increased using the aramid fiber ribbon of two layers of different-thickness in cable configuration.Its
It is narrow the web fabric or tubing formed using aramid fiber yarn as material knitting, there is high intensity, thickness has 0.4
~2mm, its stretch modulus are 3 times of steel wire, and 2 times of glass, its use temperature range is wide.With high temperature resistant, fire protection flame retarding, weight
The advantages that amount is light, high intensity, high-modulus, low-shrinkage, the good mechanical property such as shellproof, shock resistance, dielectricity is good, it is anti-in individual
The fields such as shield, bullet resistant material have extensive use.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 by rapid dispersion energy within the shortest time.
Increase FRP armors 104 further improve the intensity of optical cable, and glass fiber reinforced composite plastic bar (FRP) has
The superior functions such as light weight, modulus height, reinforcer 109 of the phosphating steel wire as optical cable is often substituted in optic cable design, is met
Certain tensile strength, while there is anti-extraneous stress.When this gunshot-proof optical cable designs, shield is outer inside sets more circles
Shape FRP, using spiral strand mode closing lay, to form one layer of armour protective layer.The further external force band such as buffering, scattered 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 intensity gunshot-proof optical cable, using light-duty complete
What dielectric structure can be achieved on.
3), all dielectric provided in this embodiment make somebody a mere figurehead gunshot-proof optical cable meet optical cable field make somebody a mere figurehead use stretching, infiltration
Deng full performance test requirement 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.
