Background technology
With the development of access technology and optical cable technology, the broadbands FTTH construction scale is increasing, and various users introduce light Cable technology is also more and more ripe.According to market survey, used indoor and outdoor leading in cable includes following several currently on the market Kind structure:Self-bearing type butterfly leading in cable, indoor and outdoor circular lead-in optical cable, air-blowing micro-cable, wherein self-bearing type butterfly leading in cable Application time is long, range is wide, technology maturation;Indoor and outdoor circular lead-in optical cable is a new product of recent year development, is adopted It replaces colored optical fiber to be convenient for into end with tight tube fiber, and aramid yarn has been selected so that optical cable is more soft as reinforcer, in state Internal region-by-region is by prodigious welcome;Air-blowing micro-cable uses more, other areas seldom use, because being related into Europe This is higher.
Rodent is more for some areas open air, and conventional leading in cable is preferable since structure size limitation is difficult to play Anti-bite effect, addition pungent element is again not environmentally in sheath;In addition with the increase of engineering construction, the laying environment of cable is also more next More complicated, in some external areas, conventional leading in cable has gone wrong again and again in laying, such as cable jacket is by weight Impact breakage directly affects optical fiber transmission;And butterfly structure its stripping groove widely applied can be generated and be covered in cold climates Ice, suspension wire and sheath cannot closely coupled easy infiltration lead to problems such as to get rusty.In American-European some areas, social security compared with Difference, the times market such as gunslinging cause irreversible damage to cable manufactures, directly destroy communications.
Utility model content
To solve the above problems, the utility model provides a kind of indoor and outdoor leading in cable with stainless steel spiral armouring, tool Standby good mouse bite preventing ability, takes into account outdoor environment performance and flame retardant property.
The technical solution adopted in the utility model is:A kind of indoor and outdoor leading in cable with stainless steel spiral armouring, including Stainless steel is arranged outside in tight tube fiber, stainless steel spiral armor, aramid fiber braiding layer, oversheath and suspention line, the tight tube fiber Spiral armor, the outer longitudinal wrap aramid fiber braiding layer of the stainless steel spiral armor, the outer extrusion molding oversheath of the aramid fiber braiding layer, institute 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.
