Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of Aviation cable, as shown in figure 1, indulging bag screen layer including the copper strips embossing coated successively on the outside of cable core and cable core
8 and oversheath 9；The cable core includes at least one line to 1, and the He of woven shield 5 is coated with successively to outside in each line
Inner sheath 6；The line is to including mutually stranded two single lines 2, and it is exhausted that every single line includes copper conductor 3 and its outside is coated
Edge layer 4；Inner sheath and the copper strips embossing is provided with least one drainage thread 7 between indulging bag screen layer.In addition, in order to improve electricity
The mechanical strength of cable, can set glass fibre reinforcer in cable core, effectively increase the ability that cable tension is dragged.Above-mentioned volume
Screen layer 5 is knitted for copper wire or tinned copper wire woven shield.
It should be noted that compared to prior art, this Aviation cable is provided with drainage thread 7, and drainage thread is arranged on
Inner sheath and copper strips embossing are indulged between bag screen layer, it can be ensured that copper strip shielding layer is remained after laying and in long-term use
Excellent interference free performance, meets bonding requirement.
It is coated on it is pointed out that indulging bag screen layer 8 using copper strips embossing on the outside of cable core, cable can be effectively improved anti-
Toughness is not enough during multiple bending, laying installation, the problems such as screen layer is easily broken.Copper strips embossing, which indulges bag screen layer, can strengthen cable
Shielding properties, it is ensured that stable signal transmission is undistorted.
Above-mentioned insulating barrier 4 is three-layer co-extruded skin-bubble-skin physical foam insulation.Insulating resistance of cable, reduction electricity can be improved
The sending allowance of cable, reduces the mutual capacitance of cable, so that the reliability for greatly improving the security of cable and using.
It is pointed out that the internal single line of line is mutually stranded, it is preferred that twisting pitch≤300mm of line centering single line,
The line pair of twisting pitch in the range of this is made, the indexs such as cross-talk, the decay of cable are can effectively improve, the items electricity of cable is improved
Gas performance.Above-mentioned cable core uses at least one line pair, when cable core includes two and more than two lines pair, phase between each line pair
It is mutually stranded to set.
Because Aviation cable has harsher requirement, therefore, above-mentioned inner sheath and oversheath to the properties of cable
Preferably both use fluorocarbon resin oversheath, it is ensured that cable has the performance such as heat-resisting, cold-resistant, chemicals-resistant, adapt to harsh operating mode,
Effectively extend the service life of cable, current Aviation cable has also been short of in this.Furthermore it is also possible in oversheath
Inner side sets one layer of fireprotection layer, to improve fireproofing of cable performance.
To ensure that the shielding properties of cable is excellent, the copper wire or tinned copper wire diameter that above-mentioned woven shield is used should >=
0.1mm, and braiding tight ness rating answers >=85%.
When this cable makes：
First the insulated single wire of two different colours is carried out to be made by twisting line pair；Then copper is externally selected in stranded complete line
Silk or tinned copper wire simultaneously weave one layer of woven shield 5 using weaving；
One layer of inner sheath 6 is extruded outside woven shield 5 afterwards, bag equipment is indulged outside inner sheath 6 using embossing, cladding one
Layer copper strips embossing indulges bag screen layer 8.
Draw aerial drainage line 7 at least provided with one between inner sheath 6 and copper strips embossing indulge bag screen layer 8 afterwards, finally in copper
Band embossing is indulged and extrudes one layer of oversheath outside bag screen layer 8.
This Aviation cable has the performances such as heat-resisting, cold-resistant, chemicals-resistant corrosion, and service life is long, good operating stability.Its
In, it is individually shielded to carrying out to each line using copper wire or tinned copper wire braiding, the shielding properties and mechanical-physical of cable can be improved
Performance, reduces line signal between and interferes.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
