It states oversheath to be connected and fixed with suspention line, the suspention line includes the sheath of galvanized strand wires and extrusion molding outside galvanized strand wires
Layer, the restrictive coating are integrally formed with oversheath.
The 304 grade stainless steel wire of selection of the stainless steel spiral armor is made after flattening, after stainless steel wire flattens
Thickness is 0.25 ± 0.1mm, and the outer diameter of 0.8 ± 0.1mm of width, stainless steel spiral armor are 1.8 ± 0.2mm.
The galvanized strand wires is that 7 zinc-coated wires are made by twisting, with restrictive coating can tight bond, and with soft
Characteristic that is soft, being not susceptible to bending.
The tight tube fiber includes the tight sleeve layer of colored optical fiber and extrusion molding outside colored optical fiber, and tight sleeve layer uses LSZH systems
At.
The outer diameter of the tight tube fiber is 0.9 ± 0.05mm, and tight tube fiber stripping performance meets disposable stripping 2cm.
The oversheath selects fire-retardant polyethylene material to be made, and the aramid fiber braiding layer utilizes mold core using aramid fiber braid over braid
Taper is molded naturally, and aramid fiber braid over braid is intact by stainless steel spiral armor cladding, and surface is without apparent flaw.It is compiled using aramid fiber
Ribbon can not only provide pulling force, but also shellproof, and general aramid yarn, only have booster action.
The utility model has the beneficial effects that：1, using stainless steel spiral armouring, the grinding tooths such as squirrel can not only be effectively prevent
Destruction of the class animal to optical cable, it is most important that the side pressure performance of leading in cable 2200N/10cm outside conventional chambers can be improved
To >=6000N/10cm, optical fiber attenuation is without significant change；2, it selects galvanized strand wires to suspend line in midair as optical cable, well solves
The problem of not being easy to happen Relative sliding closely is bonded between reinforcement and sheath, is more efficiently prevented from reinforcement and is got rusty, also has
There is characteristic that is soft, being not susceptible to bending；3, oversheath selects flame-proof polyethylene, has mechanical strength more higher than LSZH, but
It is lower than PE material tearing strengths, easy stripping construction, and meet the fire retardancy that PE sheaths do not have；4, LSZH hard-pressed bale light is selected
Fibre, convenient for quickly being terminated with most connectors on the market；5, it selects aramid fiber to be woven in outside stainless steel spiral armouring to be formed
One layer of longitudinal wrap band structure, can not only provide pulling force, also have good shellproof anti-gunshot performance；6, relative to conventional outdoor armour
Rodent-resistant cable is filled, cable size is small, light-weight, and the scope of application is wider.
