Abstract
The utility model relates to an outdoor single sheath steel tape armor buried optical cable. An outer sheath is arranged outside a steel tape. A central strengthening member is arranged in the steel tape. A water blocking yarn winds around the central strengthening member. Loose sleeves and a filling rope are arranged between the inner surface of the steel tape and the outer surface of the central strengthening member. Water blocking cable pastes are filled between the central strengthening member, the loose sleeves, the filling rope and the steel tape. Optical fibers are arranged in each loose sleeve. Each loose sleeve is filled with a fiber paste. The outdoor single sheath steel tape armor buried optical cable provided by the utility model has the advantage of compact and reasonable structure, can provide a corresponding protective role, is suitable for directly buried installation, and can ensure that the cable can meet the requirements of strain and attenuation of the optic cable and the optical fiber in installation and operation processes.
Description
Technical field
The utility model relates to a kind of optical cable, especially a kind of outdoor single sheath steel-tape armouring optical fiber cable for direct burial.
Background technology
The optical cable direct-burying system of laying is widely used, and lightguide cable link crosses the river, cross the mountain, gap bridge, cross the complex barrier thing such as villages and small towns and design and construct and generally all use the system of laying of direct-burried.Because the optical fiber cable for direct burial line facility mainly is arranged on outdoorly or open-air, and outdoor or open-air environment is more abominable, so will carry out necessary protection to cable.The protection of optical fiber cable for direct burial comprises several the contents such as the anti-mechanical damage, overcurrent proof, lightning protection, anticorrosion, protection against rodents, insect protected, flood control of optical cable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and have good protective action, can be widely used in outdoor single sheath steel-tape armouring optical fiber cable for direct burial of telecommunications and interoffice communication transfer.
The technical scheme that provides according to the utility model, described outdoor single sheath steel-tape armouring optical fiber cable for direct burial, be provided with oversheath outside steel band, be provided with central reinforce member in steel band, be wound with water blocking yarn on central reinforce member, be provided with loose sleeve pipe and gasket for packing between the outside surface of the inside surface of steel band and central reinforce member, be filled with the cable cream that blocks water between central reinforce member, loose sleeve pipe, gasket for packing and steel band, be provided with optical fiber in every loose sleeve pipe, be filled with fine cream in loose sleeve pipe.
The outside diameter of described loose sleeve pipe is 1.7 ~ 1.8mm.Described loose sleeve pipe adopts polybutylene terephthalate to make.
The diameter of described gasket for packing is 1.7 ~ 1.8mm.
The thickness of described oversheath is 1.7 ~ 2.1mm.Described oversheath adopts high density PE material to make.
The utility model compact conformation rationally, can provide corresponding protective action, is suitable for directly buried installation, and can guarantee that cable can satisfy strain and the decay requirement of optical cable and optical fiber itself in the installation and operation process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this outdoor single sheath steel-tape armouring optical fiber cable for direct burial, be provided with oversheath 9 outside steel band 8, be provided with central reinforce member 1 in steel band 8, be wound with water blocking yarn 2 on central reinforce member 1, be provided with 4 loose sleeve pipes 6 and a gasket for packing 7 between the outside surface of the inside surface of steel band 8 and central reinforce member 1, be filled with the cable cream 3 that blocks water between central reinforce member 1, loose sleeve pipe 6, gasket for packing 7 and steel band 8, be provided with 6 optical fiber 4 in every loose sleeve pipe 6, be filled with fine cream 5 in loose sleeve pipe 6.
The outside diameter of described loose sleeve pipe 6 is 1.7 ~ 1.8mm.Described loose sleeve pipe 6 adopts polybutylene terephthalate to make.
The diameter of described gasket for packing 7 is 1.7 ~ 1.8mm.
The thickness of described oversheath 9 is 1.7 ~ 2.1mm.Described oversheath 9 adopts high density PE material to make.
Described central reinforce member 1 guarantees cable when being subject to maximum installation pulling force and maximum operation pulling force in order to the stress requirement of cable to be provided, and optical fiber 4 strains meet the requirements of numerical value;
Described steel band 8 plays the effect of protection against the tide and protection against rodents, anti-ant as the armor of optical cable;
Described loose sleeve pipe 6 adopts PBT material (polybutylene terephthalate, English name polybutylene terephthalate) to make;
Described oversheath 9 adopts high density PE materials to make, and can play antiultraviolet, anticorrosion, shockproof effect to the pipeline cable.
When the utility model is made, first overlap operations at the outside of optical fiber 4 extrusion molding PBT pine sleeve pipe 6 by two, water blocking yarn 2 is on central reinforce member 1, pine sleeve pipe 6 and gasket for packing 7 mode by S-Z layer strand be wrapped in central reinforce member 1 around, and fill the cable cream 3 that blocks water in the space around loose sleeve pipe 6 and gasket for packing 7, total is fixed with the bundle yarn, forms cable core structure; Steel band 8 is placed on outside cable core structure, and high density PE oversheath 9 extrusion moldings are in the outside of steel band 8, thus formation direct-burried cable cable body.
The utility model has been owing to having adopted steel-tape armouring, and is directly buried installation, but stretch-proof, wear-resistant, shock resistance, withstand voltage flat alternating bending, reverse, circumnutate (angle of bend is no more than 90 ℃), gunslinging etc. have good mechanical property and temperature characterisitic;
The utility model adopts steel band double plastic-coated armouring and is filled in the cable cream that blocks water on every side and improved the anti-moisture vapor transmission ability of cable, and makes cable reach the purpose of protection against rodents;
The utility model transmission speed is fast, distance, good confidentiality, anti-electromagnetic field interference, good insulating, chemical stability is good, the life-span is long, loss is low, has good characteristic and economic benefit;
The utility model is applicable to long distance communication and communicates by letter with interoffice.
