Background technology
Along with widely using of cable, more and more higher to the requirement of cable.Especially in small space, when cable laying, require cable current capacity and using function on the one hand, on the other hand the diamagnetic jamming performance of cable is also had higher requirements.In long tube use procedure, flat cable is unsymmetric structure, and when electric power transfer, the electromagnetic induction produced because of the imbalance in magnetic field can cause magnetic hysteresis loss, makes electric cable heating.Therefore, round cable is suitable for applied environment more widely.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of circular anti-interference multifunctional cable, its compact conformation, good in anti-interference performance.
The circular anti-interference multifunctional cable of the one that the present invention proposes, comprises cable core, lapping layer, secondary shielding layer and restrictive coating; Cable core comprises a supporting-core, multiple conducting wires and a holding wire, and supporting-core is made up of elastomeric material, and every root wire all comprises the conductor being positioned at middle part and the first insulating barrier being coated on conductor outside, and wire has sector crosssection; Holding wire comprises four parallel longitudinal signal cores, between signal core and outside extrudes the second insulating barrier, holding wire has circular cross-section, and holding wire outside is coated with the first screen, and multiple conducting wires and holding wire have the cable core of circular cross-section around the parallel longitudinal formation of supporting-core; Lapping layer is coated on cable core outside, and secondary shielding layer is coated on lapping layer outside, and it is outside that restrictive coating is coated on secondary shielding layer.
Preferably, the first screen employing double-sided metal plastics composite band is wrapped to be formed, and be metal level in the middle of it, both sides are plastic layer.
Preferably, conductor forms by multiple copper free wire is stranded.
Preferably, the first insulating barrier adopts crosslinked polyetylene insulated layer.
Preferably, supporting-core adopts elastomeric material to make.
In the present invention, the circular anti-interference multifunctional cable proposed, comprise a supporting-core be made up of elastomeric material, multiple conducting wires and a holding wire, every root wire all comprises the conductor being positioned at middle part and the first insulating barrier being coated on conductor outside, wire has sector crosssection, holding wire comprises four signal cores, between signal core and outside extrudes the second insulating barrier, holding wire outside is coated with the first screen, and multiple conducting wires and holding wire have the cable core of circular cross-section around the parallel longitudinal formation of supporting-core; Lapping layer is coated on cable core outside, and secondary shielding layer is coated on lapping layer outside, and it is outside that restrictive coating is coated on secondary shielding layer.In said structure arrangement, on the one hand, compared with the round cable arranged with the isosceles triangle of equal ampacity, the reduced cross-sectional area nearly 30% of cable core, reduces the space needed for cable distribution, on the other hand greatly, cable core structure is compact and stable, external force be difficult to change between it in conjunction with layout, more on the one hand, double-deck anti-interference layer ensure that the interference free performance of cable.
