Abstract
The invention provides a fireproof control cable. The fireproof control cable comprises an inner sheath, an inner conductor, an insulating layer and an outer sheath which are arranged from inside to outside, wherein the inner conductor comprises a plurality of wire groups arranged between the inner sheath and the insulating layer along the peripheral direction; a weaving layer formed by mixing and weaving tinned copper wires and Aramid yarns is arranged between the inner conductor and the insulating layer; the wire groups are respectively adhered with the inner sheath and the insulating layer; and fireproof layers are arranged between the inner conductor and the inner sheath as well as between the insulating layer and the outer sheath. The inner conductor created in the fireproof control cable is arranged in the peripheral direction of the inner sheath, the fireproof control cable is high in shock resistance and high in strength, the inner sheath plays the roles of buffering and damping, the wire groups are effectively isolated by filling reinforcing pieces, and the functions of impact resistance and compressional deformation resistance can also be achieved; and the control cable can endure long-time coiling and dragging motions, and also has extremely excellent tension stress characteristic and the characteristics such as insulation and voltage resistance, coiling and voltage resistance and abrasion resistance.
Description
Technical field
The invention belongs to control cables technical field, especially relates to a kind of fire-type control cables.
Background technology
Control cables be widely used in cable TV transmission network network system, closed-circuit television system, monitoring system,In the wire transmission network systems such as safety and protection system, it passes as backbone, main line or service mainThe information such as defeated television image, sound, data, symbol, are also applied to other impedances of similar applicationsIn the wire transmission network of joining, be more suitable for being applied in the relative rugged environment of laid condition, reach goodLaser propagation effect. Along with people's living standard improves constantly, for obtaining more real transmission information,Requirement to coaxial cable is also more and more higher. Radio frequency coaxial-cable of the prior art, due to cable designThere is defect, in work progress, sheath often occurs and puncture and directly injure outer conductor and cable hits flat afterwardsThe serious quality problems such as weigh wounded, cause communication disruption, affect the normal production and operation and life.
Innovation and creation content
In view of this, the invention is intended to propose a kind of fire-type control cables, to improve the anti-of cableImpact capacity, is applicable under severe environment for use long service life.
For achieving the above object, the technical scheme of the invention is achieved in that
A kind of fire-type control cables, comprise the inner sheath that arranges from inside to outside, inner wire, insulating barrier andOversheath; Described inner wire comprises the several lines that are along the circumferential direction arranged between inner sheath and insulating barrierGroup; Between described inner wire and described insulating barrier, be provided with the braiding being formed by tinned copper wire and aramid fiber yarn shufflingLayer; Described line group bonds with inner sheath and insulating barrier respectively; Between described inner wire and described inner sheath,And between described insulating barrier and oversheath, be all provided with fireprotection layer.
Further, in described braid, adopt 0.1mm tinned copper wire, and in braid, tinned copper wire coversRate is 60%.
Further, described line group is along the uniform setting of inner sheath circumferencial direction.
Further, described line group adopts oxygen-free copper core.
Further, described oversheath is outer protective polyethylene cover.
Further, between described insulating barrier and oversheath, be also provided with cushion rubber layer.
Further, between described inner wire and described inner sheath, be provided with the filling for separating each described line groupReinforcement.
With respect to prior art, a kind of fire-type control cables described in the invention has following excellentGesture:
The inner wire of cable is arranged on inner sheath circumferencial direction, strong shock resistance, and intensity is high, is being subject toWhen impact, inner sheath plays the effect of buffering and damping, fills reinforcement and effectively separates each line group, sameAlso play the effect of shock resistance and anti-extrusion deformation, this control cables can be applicable to severe environment for useUnder, and long service life, reliable and stable.
Brief description of the drawings
The accompanying drawing that forms the part of the invention is used to provide the further understanding to the invention,The schematic description and description of the invention is used for explaining the invention, does not form thisThe improper restriction of bright creation. In the accompanying drawings:
Fig. 1 is the structural representation of the invention.
Fig. 2 is the structural representation that is provided with cushion rubber layer and fireprotection layer in the invention embodiment.
Detailed description of the invention
It should be noted that, in the situation that not conflicting, in embodiment and embodiment in the inventionFeature can mutually combine.
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the invention in detail.
A kind of fire-type control cables, as shown in Figure 1, comprise the inner sheath 1 that arranges from inside to outside, inConductor, insulating barrier 3 and oversheath 4; Described inner wire comprise be along the circumferential direction arranged on inner sheath 1 withSeveral line groups 2 between insulating barrier 3; Between described inner wire and described insulating barrier, be provided with by tinned copper wireThe braid forming with aramid fiber yarn shuffling; Described line group 2 bonds with inner sheath 1 and insulating barrier 3 respectively;Between described inner wire and described inner sheath and between described insulating barrier and oversheath, be all provided with fire preventionLayer.
It should be noted that, between inner wire and inner sheath and between insulating barrier and oversheath, all establishingThere is fireprotection layer, can stop outside burning things which may cause a fire disaster, and the burning things which may cause a fire disaster entering from core, flameproof effect is good.
In described braid, adopt 0.1mm tinned copper wire, and in braid, tinned copper wire coverage rate is 60%.Make this control cables can stand long-time coiling and pull motion, there is extremely excellent anti-tensile Z-TEK simultaneouslyProperty, and dielectric voltage withstand, coiling is withstand voltage, the characteristic such as wear-resisting.
Wherein, described line group 2 is along the uniform setting of inner sheath 1 circumferencial direction, described inner wire and described inBetween sheath, be provided with the filling reinforcement for separating each described line group. Fill reinforcement and can adopt linen-cottonRope. Make control circuit Stability Analysis of Structures reliable, fill reinforcement and effectively separate each line group, equally also playThe effect of shock resistance and anti-extrusion deformation.
Wherein, described line group 2 adopts oxygen-free copper core, its resistance is low, elongation and density high, use effectFruit is good, ensures that control cables uses reliable and stable.
Wherein, described oversheath 4 is outer protective polyethylene cover, good insulating.
