Abstract
The utility model discloses a there is not steamed fire -retardant coaxial cable, by interior and be equipped with conductor, PE insulating layer, woven shield and oversheath outward, the crowded package of PE insulating layer is equipped with the mica tape around the covering with separate oxygen in situ sheath between woven shield and oversheath outside the conductor, the mica tape around the covering around the package outside woven shield, the mica tape around the covering outward in proper order crowded package have at a distance from oxygen in situ sheath and oversheath. The utility model discloses a shielding layer adopts the copper wire to weave, and it is insulating around having wrapped the one deck mica tape again outward that braiding density is greater than 90%, woven shield, improved the shielding effect of cable greatly, and the mica tape has fine fire -resistant characteristic and higher fire behaviour simultaneously, has formed the one deck flame retardant coating promptly outside the conductor, in addition, the mica tape is crowded in proper order outward to have wrapped around the covering and is separated oxygen in situ sheath and do not have the fire -retardant oversheath of bittern, separates oxygen in situ sheath and can decompose an aqueous vapor when the burning, effectively plays the effect of burning that prevents for the fire behaviour of this cable improves greatly, can reach the requirement of fire -retardant A class.
Description
Technical field
The utility model relates to coaxial cable technology field, is specifically related to a kind of halogen-free flameproof coaxial cable.
Background technology
In the communications field, often use coaxial cable and carry out transmission of electric signals, as the radio frequency coaxial-cable that wireless base station device is used, office's coaxial cable etc. that the exchange of central machine room and transmission equipment are used.Existing coaxial cable comprises the inner wire, insulating barrier, screen and the sheath that connect successively from inside to outside, and great majority do not arrange flame retardant coating or flame-retardant layer to prevent ignition of cable to the production of people, the live harm and loss that bring.
Utility model content
The purpose of this utility model is: for the above-mentioned technical problem existed in prior art, provides a kind of halogen-free flameproof coaxial cable.
The utility model is achieved through the following technical solutions:
A kind of halogen-free flameproof coaxial cable, be provided with conductor, PE insulating barrier, woven shield and oversheath from inside to outside, PE insulating barrier is extruded in outside conductor, Mica tape layer and oxygen barrier layer inner sheath is provided with between described woven shield and oversheath, Mica tape layer is wrapped outside woven shield, and Mica tape layer is extruded with oxygen barrier layer inner sheath and oversheath outward successively.
As preferably, described conductor adopts stranded anaerobic soft copper silk.
As preferably, described oversheath adopts fire-retardant Halogen oversheath.
As preferably, described woven shield adopts proof copper-wire braided, and count is greater than 90%.
As preferably, described oxygen barrier layer inner sheath adopts halogen-free flameproof oxygen barrier layered material to make.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Compared with prior art, screen of the present utility model adopts proof copper-wire braided, count is greater than 90%, one deck mica tape insulation that woven shield is wrapped again outward, substantially increase the shield effectiveness of cable, and mica tape has good fire-resistance property and higher fire resistance, namely defines one deck flame retardant coating outside conductor simultaneously; In addition, Mica tape layer has extruded one deck oxygen barrier layer inner sheath and halogen-free flameproof oversheath outward respectively, and oxygen barrier layer inner sheath can decomposite aqueous vapor when burning, and effectively can play the effect stoping burning, the fire resistance of this cable is improved greatly, fire-retardant category-A requirement can be reached.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1-conductor, 2-PE insulating barrier, 3-woven shield, 4-Mica tape layer, 5-oxygen barrier layer inner sheath, 6-fire-retardant Halogen oversheath.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of halogen-free flameproof coaxial cable, be provided with conductor 1, PE insulating barrier 2, woven shield 3 and oversheath from inside to outside, described conductor 1 adopts stranded anaerobic soft copper silk, PE insulating barrier 2 is extruded in outside conductor 1, between described woven shield 3 and oversheath, be provided with Mica tape layer 4 and oxygen barrier layer inner sheath 5, Mica tape layer 4 is wrapped outside woven shield 3, and Mica tape layer 4 is outer is extruded with oxygen barrier layer inner sheath 5 and oversheath successively.Wherein, oversheath adopts fire-retardant Halogen oversheath 6, woven shield 3 adopts proof copper-wire braided, count is greater than 90%, described oxygen barrier layer inner sheath 5 adopts model to be that the halogen-free flameproof oxygen barrier layered material of HW495 is made, oxygen barrier layered material can decomposite aqueous vapor when burning, and can play the effect stoping burning.
Above-described specific embodiment, further describes the purpose of this utility model, technical scheme and beneficial effect, and institute it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to the utility model.The utility model expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
