Description
Technical Field
The utility model belongs to the technical field of the cable technique and specifically relates to an all-dielectric tensile outdoor cable.
Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers disposed in a covering jacket as the transmission medium and may be used individually or in groups as telecommunication cable assemblies. With the development of society and the progress of science and technology, the information transfer is more and more efficient, the network information transfer between areas is more and more intimate, and the use amount of the optical cable is increased; meanwhile, the use of optical cables is favored by people in the industry because of low transmission loss, wide transmission frequency band, large capacity and strong anti-electromagnetic interference capability, and the use of optical cables has gradually penetrated into various fields of wired communication, including a plurality of fields such as post-and-telecommunications, broadcast communication, power communication and military communication. However, the more complicated the structure of the existing cable, the higher the production cost, and the less the number of optical fibers, the non-circular cross section of the cable, the uneven stress and the relatively poor traction resistance during winding, transportation and storage of the cable with a simple structure, which affects the service life and the service environment of the optical fibers.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the shortcoming that exists among the prior art, and provide an all-dielectric tensile outdoor cable.
The utility model discloses an outdoor cable of full medium tensile, including optic fibre and protective sheath, in the pine cover was arranged in to optic fibre more than one of which, fine cream was being filled with the intraductal gap of pine cover to optic fibre more than one, and pine cover periphery parcel has the cable cream, and the cable cream is equipped with metal protective sheath and protective sheath outward in proper order, protective sheath in the equipartition tensile steel wire rope more than two has been buried underground.
Preferably, the tensile steel wire ropes are spirally embedded in the protective outer sleeve.
As the optimization of the utility model, the loose tube is internally provided with a power line and an insulating sleeve covering the power line.
As the optimization of the utility model, the cable paste is a water-resistant layer.
As the utility model discloses a preferred, the metal protection cover is aluminium matter or steel and weaves net structure protective sheath.
The utility model discloses an outdoor cable of full medium tensile, simple structure, reasonable in design, the cross-section is the transportation and the packing of circular convenient cable, and the winding is tight real, has set up more than two in the main part and has been spiral tensile steel wire rope, and the atress is even, has strengthened the holistic tensile strength of cable, and the cable is difficult for breaking, improves the crushing resistance and the life-span of cable.

Fig. 1 is a cross-sectional view of the present invention.
Detailed Description
The following describes the all-dielectric tensile outdoor cable of the present invention with reference to fig. 1.
Example 1
The utility model discloses an outdoor cable of full medium tensile, including optic fibre 1 and protective sheath 2, optic fibre 1 more than one of which is arranged in loose tube 3, the gap in optic fibre 1 more than and the loose tube 3 is being filled fine cream 4, and 3 periphery parcel of loose tube have cable cream 5, and cable cream 5 is equipped with metal protective sheath 6 and protective sheath 2 outward in proper order, protective sheath 2 in the equipartition buried tensile steel wire rope 7 more than two underground.
Example 2
The utility model discloses an outdoor cable of full medium tensile, including optic fibre 1 and protective sheath 2, optic fibre 1 more than one of which is arranged in loose tube 3, the gap in optic fibre 1 more than and the loose tube 3 is being filled fine cream 4, and 3 periphery parcel of loose tube have cable cream 5, and cable cream 5 is equipped with metal protective sheath 6 and protective sheath 2 outward in proper order, protective sheath 2 in the equipartition buried tensile steel wire rope 7 more than two underground. Tensile steel wire rope 7 more than two is spiral buries underground in overcoat 2, and the advantage of spiral structure lies in that cable main part atress is even, and non-deformable harms when winding transportation and preserve have strengthened the holistic tensile strength of cable simultaneously, and the cable is difficult for breaking, improves the crushing resistance and the life-span of cable. The loose tube 3 is internally provided with a power wire 8, and the power wire 8 is covered by an insulating sleeve 9. The cable paste 5 is a water-resistant layer. The metal protective sleeve 6 is an aluminum or steel woven mesh structure protective sleeve, so that the transverse strength and the longitudinal strength are enhanced, the stress is uniform, and the strength and the tensile property of the cable are further improved. The cable paste is a waterproof tape wound in the optical cable, and a plurality of water-blocking powders are arranged on the waterproof tape and expand when meeting water, so that the water is effectively prevented from entering the optical cable. The fiber paste is a paste filled in the loose tube 3 in order to prevent the fiber from being damaged by the invasion of moisture and the mutual friction of the fibers during the process of manufacturing the optical cable, and the specific materials of the cable paste and the fiber paste are not particularly limited, and are common knowledge of persons in the field.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
