Abstract
The utility model provides a kind of central beam tube type cable, comprise Loose tube, be arranged on the stainless-steel tube in Loose tube and the water blocking yarn be coated in stainless-steel tube and Duo Gen light transmitting fiber, water blocking yarn meets water undergoes rapid expansion, block-water effect can be reached, and water blocking yarn substitutes the ointment of infection, there will not be the longitudinal drip of ointment and below the ointment that causes is deposited on; Stainless-steel tube can effectively be strengthened fibre-optic protection, effectively can reduce outer diameter of cable, can utilize conduit resource to greatest extent; Loose tube outer cladding phosphating steel wire layer, phosphating steel wire layer is outward polyurethane inner sheath, and polyurethane inner sheath is wrinkle steel band, and wrinkle steel band is outward polyurethane oversheath.Phosphating steel wire layer and wrinkle steel band can improve the tension resistance to compression mechanical property of cable, and physical strength strengthens, and its water tolerance, oil resistant chemical resistance are obtained for larger raising, extend endurance and the serviceable life of cable; Make cable can bear larger installation drop simultaneously, be applicable to outdoor application.
Description
Technical field
The utility model relates to optical fiber cable field, particularly relates to a kind of central beam tube type cable.
Background technology
Central beam tube type cable is inserted in by optical fiber in the spiral space Loose tube made by the plastics of high-modulus, waterproofing compound is filled in sleeve pipe, sleeve pipe applies one deck material water-proof material and armoring material outward, and two parallel steel wires are placed in both sides, and extrude pe sheath stranding.Its principal feature has: distinctive helicla flute Loose tube design, is conducive to accurately controlling optical fiber excess length, ensure that cable has good mechanical property and temperature characterisitic; Loose tube material itself has good anti-hydrolytic performance and higher intensity, fills with extraordinary ointment in pipe, has carried out key protection to optical fiber; Two parallel steel wires ensure the tensile strength of cable; Have diameter little, lightweight, easily the advantage such as to lay, but because ointment clean in Loose tube needs the expensive time, and ointment pollutes the environment, and affect cable quality, and also can be subject to the restriction of installation drop, use occasion also can be restricted simultaneously.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides one and can overcome ointment contaminated environment in cable, on the central beam tube type cable of cable communication quality without impact.
The utility model is achieved in that a kind of central beam tube type cable, comprise Loose tube, be arranged on the stainless-steel tube in described Loose tube and the water blocking yarn be coated in described stainless-steel tube and Duo Gen light transmitting fiber, described Loose tube outer cladding phosphating steel wire layer, described phosphating steel wire layer is outward polyurethane inner sheath, described polyurethane inner sheath is wrinkle steel band, and described wrinkle steel band is outward polyurethane oversheath.
Further, composite bed is provided with outside described water blocking yarn.
Further, described light transmitting fiber is UV curing optical fiber.
Further, be provided with symmetrically and the reinforcement be arranged in parallel in described polyurethane inner sheath.
Further, described reinforcement is steel wire, and the distance between described reinforcement and described polyurethane inner sheath edge is 1mm-2mm.
The utility model provides a kind of central beam tube type cable, comprise Loose tube, be arranged on the stainless-steel tube in described Loose tube and the water blocking yarn be coated in described stainless-steel tube and Duo Gen light transmitting fiber, water blocking yarn meets water undergoes rapid expansion, block-water effect can be reached, and water blocking yarn substitutes the ointment of infection, there will not be the longitudinal drip of ointment and below the ointment that causes is deposited on; And environmental pollution can not be there is, and eliminate the cleaning to ointment, constructability more; Stainless-steel tube can effectively be strengthened fibre-optic protection, effectively can reduce outer diameter of cable, can utilize conduit resource to greatest extent; Described Loose tube outer cladding phosphating steel wire layer, described phosphating steel wire layer is outward polyurethane inner sheath, and described polyurethane inner sheath is wrinkle steel band, and described wrinkle steel band is outward polyurethane oversheath.Phosphating steel wire layer and wrinkle steel band can improve the tension resistance to compression mechanical property of cable, and physical strength strengthens, and its water tolerance, oil resistant chemical resistance are obtained for larger raising, extend endurance and the serviceable life of cable; Make cable can bear larger installation drop simultaneously, be applicable to outdoor application.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
