Abstract
The invention relates to a protections sleeve for an all-dielectric self-supporting cable and relates to the technical field of the protection sleeve. According to the protection sleeve, an outer-most layer of an outer protection layer is the protection sleeve, a cable core internally comprises multiple parallel fibers, a double-face plastic-coated steel band is arranged at an inner ring of the protection sleeve, an inner protection sleeve is arranged at an inner layer of the double-face plastic-coated steel band, the cable core is externally wrapped in a loose sleeve, the loose sleeve is at the outer layer of the cable core, a water blocking fiber paste is filled in the loose sleeve, a metal reinforcement member is arranged at a center position of the cable, a filling member is filled in the loose sleeve, and a water blocking cable paste is sprayed on the double-face plastic-coated steel band. The protection sleeve has a simple structure, a spraying type cable is utilized, cost is greatly saved on the condition that water seepage performance of the cable is not influenced, a layer of the special-purpose spraying cable paste is directly sprayed on the double-face plastic-coated steel band, the excellent water blocking effect is realized, service life of the cable is guaranteed, and the protections sleeve is quite suitable for being used for construction in a pipeline and can be mounted on site in a factory to guarantee correct adaptation and structural integrity.
Description
Technical field
The present invention relates to protective jacket technical field, be specifically related to the protective jacket of a kind of All Dielectric self-support.
Background technology
nullOptical cable damage in recent years is the most serious，Will again set up new optical cable the most every year，This brings greatly puzzlement to power department，Expend a large amount of manpower and materials，Communication is interrupted often，Cause immeasurable loss，A kind of optical cable protecting sleeve is needed so eager，With solve matter as a fire singeing one's eyebrows it，Some producers copy the method for termite-resistant rodent-resistant，Produce some anti-unfirmly closing optical cables，Effect is the most undesirable，Because they are to use chemical method，I.e. in sheath material, add a kind of pungent substance，Allow birds away from，But this optical cable，Elapse over time，Pungent taste is the most thin out，Generally the most invalid after half a year，At present，The jacket structure of optical cable outer layer is usually by moistureproof composite metal belt and polyolefin jacket material group，But it is applied to highfield、Optical cable in strong electromagnetic environment then can only use the optical cable of full nonmetal structure，Reinforcing element and polyolefin jacket material including nonmetallic materials，The termite-resisting function of full non metallic sheath optical cable，Now it is typically employed in outside polyolefin jacket one layer of certain thickness nylon material of extruding，The hardness relying on nylon material special reaches termite-proof purpose，The resistance to many employings of damaged by rats ability add containing glass fibre reinforcement layers，To reaching certain protective action，But these nonmetal anti-ant versions all have some limitations，Harmful，Not environmentally.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of waterproof, fire prevention, anti-mechanical damage, anti-biological damage, anticorrosion, anti-lightning strike and forceful electric power, environmental protection and the protective jacket of All Dielectric self-support to human body fanout free region.
For achieving the above object; the technical solution used in the present invention is: the protective jacket of a kind of All Dielectric self-support, and it comprises outer jacket, protective jacket, cable core, double plastic-coated steel band, inner sheath, pine pipe box, block water fine cream, metal reinforcement, filling member, block water cable cream, protective layer；Outer jacket outermost layer is protective jacket, many parallel optical fiber are included in cable core, double plastic-coated steel band is positioned at protective jacket inner ring, inner sheath is positioned at the internal layer of double plastic-coated steel band, cable core parcel is positioned at its outer layer by pine pipe box, and the fine cream that blocks water is filled in pine pipe box, and metal reinforcement is positioned at the center of optical cable, filling member is filled on pine pipe box, and the cable cream that blocks water is sprayed on double plastic-coated steel band.
Further, described protective jacket is that vinyon is made.
Further, described inner sheath is that vinyon is made.
Further, described cable core is arranged in rectangular-shaped composition by 20 to 150 optical fiber.
Further, described metal reinforcement is steel wire.
After using said structure, the invention have the benefit that its simple in construction, use the jet printing type optical cable can effectively save great amount of cost on the premise of optical cable permeability performance does not affects, directly on steel band, spray one layer and spray special cable cream, and play good block-water effect, use the double protection at protective jacket and inner sheath simultaneously, spraying waterproof cable cream between some sub-optical cable units in steel band, effectively prevent the infringement that optical cable is caused by the various factors such as sewage and mouse, ensure that the service life of optical cable, it is highly suitable for construction usage in pipeline, can in factory in-site installation, to guarantee the integrity of correct adaptation and structure.
