Abstract
The invention discloses a double-shielded insulated communication cable. The cable comprises an outer sheath layer, a nylon sheath layer and an inner insulation layer which are arranged successively from the outside to the inside. A reinforcing cable core is arranged in the inner insulation layer; the periphery of the reinforcing cable core is twisted and wrapped by a conductive cable core in the insulation layer; an outer insulation layer is arranged between the outer sheath layer and the nylon sheath layer; and the outer insulation layer and the inner insulation layer are made of zirconia. Through many times of experiment researches, an inventor discovers that through preparing the outer insulation layer and the inner insulation layer by zirconia, excellent insulation and shielding effects are realized; an excellent anti-interference effect can be realized only through arranging the two structures with the nylon sheath layer separately and crossly; through arrangement of the reinforcing cable core, the bend resistance of the communication cable is improved; moreover, because the periphery of the reinforcing cable core is twisted and wrapped by the conductive cable core in the insulation layer, the cable cores in the insulation layer are integrated; and further the bending resistance and distortion resistance of the communication cable in the radial direction are improved.
Description
Technical field
The invention belongs to communication technical field, especially relate to a kind of double shield insulating communication cable for information transmission。
Background technology
Logical line cable is the cable of transmission phone, telegram, fax paper, TV and broadcast program, data and other signals of telecommunication。Formed by the wire stranding of more than a pair mutually insulated。Communication cable compared with overhead line, have that message capacity is big, transmission stability is high, good confidentiality, less by the advantage such as natural conditions and external influences。
Disclosed in Chinese patent literature CN203205141U, one discloses a kind of communication cable, including cable core and the outer jacket being positioned at outside cable core, at least one plastic optical fiber it is additionally provided with in described outer jacket, during use, collect end or use end that plastic optical fiber is applied light source, plastic optical fiber in this communication cable will be shinny, such that it is able to be able to conveniently find the position of this root communication cable other end。As preferably: set the plastic optical fiber of more than two in described outer jacket；So, not only applying during light source more convenient, and form at least one standby plastic optical fiber, during use, reliability is higher；Described outer jacket includes the insulating barrier, screen layer and the sheath that are arranged concentrically from inside to outside；Certainly, outer jacket can also adopt other version of the prior art；Communication cable designed by this technical scheme, it is possible to collecting end or using end to look for the position of its other end easily, from without as in the prior art each communication cable being made marks, installing maintenance more convenient。
Although the communication cable disclosed in above-mentioned patent documentation solves installs the technical problem safeguarded, but in use communication quality is less desirable, and capacity of resisting disturbance is poor。
Therefore, it is necessary to work out a kind of new communication cable, the communication cable that capacity of resisting disturbance is strong。
Summary of the invention
The technical problem to be solved in the present invention is, provides the double shield insulating communication cable that a kind of anti-capacity of resisting disturbance is strong。
For solving above-mentioned technical problem, the technical solution used in the present invention is, this double shield insulating communication cable, is disposed with external sheath layer, nylon sheath wire layer and inner insulating layer from outside to inside；Being provided with reinforced core in described inner insulating layer, described reinforced core is peripheral stranded and is wrapped in the conductor wire core in described inner insulating layer；It is additionally provided with external insulation layer between described external sheath layer and nylon sheath wire layer；Described external insulation layer and inner insulating layer are zirconium oxide。
Inventor finds through many experiments research, and external insulation layer and inner insulating layer are that zirconium oxide has extraordinary insulation shielding effect, and double-layer structure need to separately intersect and the setting of nylon sheath wire layer, just has extraordinary anti-jamming effectiveness；Reinforced core is set, the bending resistance making communication cable improves, additionally, reinforced core is peripheral stranded and is wrapped in the conductor wire core in described insulating barrier, make the cable in insulating barrier become as a whole, further improve the communications cable radially counter-bending/distortion performance。
Preferably, two metal detection lines of symmetry it are provided with between described inner insulating layer and nylon sheath wire layer。The effect of metal detection line is in that, whether whether monitor in real time communication cable is stolen or be interrupted, and is accurately judged to the position of existing problem, makes feedback in time。
Preferably, described metal detection line and described reinforced core be arranged in parallel。
Preferably, described reinforced core is arranged at intervals with some radially protrusion and separate reinforcement。
Spaced effect is in that so that pullling communication cable in the longitudinal direction, this pulling force of the more effective reply of internal core；Separate reinforcement, it is therefore an objective to reinforcement is set cable can not be hindered to arrange in insulating barrier。
Preferably, described reinforcement is in cross in terms of cross section, and described reinforced core is centrally located；Described conductor wire core is stranded and is evenly distributed in the gap of adjacent said rib。
