Abstract
The present case is a wear -resisting overpressure resistant optical cable, includes: the nylon oversheath, it is outermost inoxidizing coating, the inner sheath, it is located nylon oversheath inlayer, double coated aluminium strip, it is located the inner sheath inner circle, fiber core, it comprises the multifiber, PBT loose tube will the mode of fiber core parcel is located its skin, the fine cream that blocks water, it is filled and is in in the PBT loose tube, metal reinforcement, it is located the center of optical cable, hinder water -blocked cable cream, it is in with the spraying the last mode of double coated aluminium strip fill in in the double coated aluminium strip, the steel wire armouring, its evenly distributed in on the external diameter of inner sheath. Evenly distributed armouring wire outside the inner sheath is adopted in the present case, can improve the compressive capacity of optical cable effectively.
Description
Technical field
The utility model relates to optical cable, particularly relates to a kind of wear-resisting withstand voltage optical cable.
Background technology
The technology that usual outdoor filled type communications optical cable is identical, only in the difference of filling cable cream part, ointment pump or other factice for filling parts can not be used, spraying cable cream device is installed, be sprayed on steel, aluminium strip by special for spraying cable cream before steel, aluminium strip enter preforming tool, each rice sprays half meter of cable cream; If alone spraying can not play block-water effect, can use before spraying and fill cable cream, and use vulcanite scraper cream mould all to be struck off by cable cream all around cable core, only stay the cable cream at the stranded place of cable core, re-use spraying afterwards.Purposes due to inside cable determine the resistance to tension of optical cable poor, there is no stop water yet, be not suitable for laying use in pipeline, may there is sewage and mouse etc. in pipeline, outside is easily worn, and cable lifetime is in the presence of a harsh environment seriously affected by environment simultaneously.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of wear-resisting withstand voltage optical cable, is intended to realize that structure is simple, barrier propterty good, durable optical cable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A wear-resisting withstand voltage optical cable, comprising:
Nylon outer sheath 1, it is outermost protective layer;
Inner sheath 2, it is positioned at described nylon outer sheath internal layer;
Double plastic-coated aluminium strip 3, it is positioned at described inner sheath inner ring;
Fiber cores 5, it is made up of multifiber;
PBT pine pipe box 4, is positioned at by the mode that described fiber cores is wrapped up in its skin;
Block water fine cream 6, and it is filled in described PBT pine pipe box;
Metal reinforcement 7, it is positioned at the center of described optical cable;
Block water cable cream 8, and it is filled in described double plastic-coated aluminium strip in the mode be sprayed on described double plastic-coated aluminium strip;
Wire armoring 9, it is uniformly distributed on the external diameter of described inner sheath.
Preferably, described wear-resisting withstand voltage optical cable, wherein, the material of described nylon outer sheath is nylon material.
Preferably, described wear-resisting withstand voltage optical cable, wherein, described oversheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, described wear-resisting withstand voltage optical cable, wherein, described wire armoring is made up of even number bar armouring wire.
Preferably, described wear-resisting withstand voltage optical cable, wherein, described fiber cores is made up of 12 to 144 optical fiber.
Preferably, described wear-resisting withstand voltage optical cable, wherein, described PBT pine pipe box material is polybutylene terephthalate.
Preferably, described wear-resisting withstand voltage optical cable, wherein, described metal reinforcement material is stainless steel.
The beneficial effects of the utility model: the utility model structure is simple, under the prerequisite using jet printing type optical cable not affect at optical cable permeability performance, do not use and fill cable cream or use a small amount of filling cable cream, directly on aluminium strip, spray one deck sprays special cable cream, and every 1 meter of length can fill about half meter, save most ointment, and play good block-water effect; Nylon outer sheath is provided with in the outside of inner sheath, spraying waterproof cable cream between some sub-optical cable units simultaneously in aluminium strip, effectively prevent the infringement that the various factors such as sewage and mouse causes optical cable, ensure that the serviceable life of optical cable, be highly suitable for construction usage in pipeline; Adopt and be uniformly distributed armouring wire outside inner sheath, effectively can improve the anti-pressure ability of optical cable, this structure Absorbable rod and stop most of external mechanical power and environmental factor on the impact of optical cable inner fiber, can ensure that optical cable has outdoor optical cable advantage and is suitable in features such as outdoor laid lay.
