Abstract
The utility model belongs to the technical field of communication, which relates to a strong optical cable with electromagnetic field resistance, aiming to solve the technical problems of the prior art that the structure strength is low; the performance is poor and the like. The optical cable comprises a center reinforcing piece and a plurality of cable cores, wherein the periphery of each cable core is respectively sleeved with a loose sleeve tube. Fiber paste is arranged in the loose sleeve tube, and surrounds the cable core. The loose sleeve tubes are stranded around the center reinforcing piece. A first protective jacket for coating each loose sleeve tube is arranged on the periphery of each loose sleeve tube. A plurality of zinc-plating steel wires are arranged on the periphery of the first protective jacket, and wound onto the first protective jacket. A second protective jacket is arranged on the periphery of the zinc-plating steel wires, and used for coating the zinc-plating steel wires. The utility model has the advantages that the weatherproof property is good, the high and low temperature property is good, and the optical fiber cannot be damaged by hydrogen due to the oxidization of phosphorized steel wires or steel strip; the tension strength, side compressive strength and shock strength are high, and the metal element is completely isolated from the cable cores, so the optical cable can be normally used under the environment of strong electromagnetic field; the structure is compact, the production process is simple, and the optical cable can be produced by the traditional equipment.
Description
Technical field
The utility model belongs to communication technique field, relates to optical cable, especially relates to a kind of anti-electromagnetic field powerful optical cable.
Background technology
Traditional optical cable adopts two kinds of structures: 1, central reinforce member adopts steel wire, at cable core outer wrapping steel (aluminium)-PE sheath; 2, central reinforce member adopts glass fibre, at cable core outer wrapping PE sheath.Adopt first kind of structure to have following shortcoming:, thereby to cause the loss of optical cable significantly to increase because of the oxidation of phosphatization steel wire or steel aluminium strip makes optical fiber suffer hydrogen loss; Influence is used under the environment of strong-electromagnetic field.Adopt second kind of structure to have following shortcoming: tensile strength is not enough; Impact resistance is poor.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example; Chinese patent literature discloses this optical cable tensile core of a kind of optical cable tensile core [applying date: 95217627.0] and mainly has been included in and fibrous bundle periphery bag week is coated with protective seam, and the fibrous bundle that effective quantity is coated with protective seam is the boundling shape and arranges the back and be coated with outer back curing molding in its periphery and make.It has solved existing product stretch-proof ability, electromagnetic signal is disturbed shortcomings such as big, has light weight, and the intensity height disturbs advantages such as little to electromagnetic signal.Such scheme has improved properties of optical fiber cable to a certain extent, but still can't fundamentally solve prior art problems.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of structural strength height is provided, and stable performance is easy to the anti-electromagnetic field powerful optical cable of processing and manufacturing.
For achieving the above object, the utility model has adopted following technical proposal: this anti-electromagnetic field powerful optical cable, comprise central reinforce member and some cable cores, the periphery of every cable core is with a loose sleeve pipe respectively, in loose sleeve pipe, be provided with the fine cream of going along with sb. to guard him cable core, described loose sleeve pipe is stranded around central reinforce member, it is characterized in that, the periphery of described loose sleeve pipe is provided with first protective jacket that each loose sleeve pipe is coated, be provided with some windings zinc-coated wire thereon in the periphery of first protective jacket, be provided with second protective jacket that each zinc-coated wire is coated in the periphery of zinc-coated wire.
Zinc-coated wire number in the utility model is determined according to required tension force, therefore can design and produce the various optical cable of structure.
In above-mentioned anti-electromagnetic field powerful optical cable, also be provided with water barrier between described first protective jacket and the loose sleeve pipe, described water barrier is made by polyester belt.
In above-mentioned anti-electromagnetic field powerful optical cable, described central reinforce member is made by the FRP material.
In above-mentioned anti-electromagnetic field powerful optical cable, described first protective jacket and second protective jacket are made by the PE material.
In above-mentioned anti-electromagnetic field powerful optical cable, factice for filling between described water barrier and the loose sleeve pipe.
In above-mentioned anti-electromagnetic field powerful optical cable, described cable core is fine bundle of all-dielectric optically or fibre ribbon.
In above-mentioned anti-electromagnetic field powerful optical cable, the core of described cable core is counted summation and is no more than 288.
Compared with prior art, the advantage of this anti-electromagnetic field powerful optical cable is: 1, weather resistance is good, high temperature performance is excellent, can not make optical fiber suffer hydrogen loss because of the oxidation of phosphatization steel wire or steel band, avoids causing the loss of optical cable significantly to increase.2, anti-ly open, lateral pressure resistant and excellent in cushion effect, hardware and cable core are isolated fully, possess protection against rodents, prevent the ant performance, under the environment of strong-electromagnetic field, can normally use, particularly suitable on the abrupt slope, marsh, mountain area, wait environment under water.3, compact conformation, production technology are simple, utilize existing equipment to produce, and need not to add any servicing unit.
