Toward be cable install operation service life it is shorter, just do not break down and scrap to scheduled time cable.There is above-mentioned phenomenon
Main cause be：
1) conductor strand direction, such as Patent No.：201410416622, patent name is：Electromagnetism interference flexible cable
Patent document described in, the strand that strand type conductor is used again with again twist when each layer twisted wire direction to be identical, such design is led
When monofilament of the body in its conductor under stretching twisted state is in flexural deformation, the stress that conductor is produced influences each other, so that
Exacerbate the probability that phenomenon of rupture occurs for monofilament.
2) bunch and the lay ratio of beam twine, multiple stranded conductor and cable core are big, and deformation surplus is small when stretching is with distortion, directly
The deformational stress for acting on cable axial direction is big, easily occurs conductor, cable core distortion and folds and disconnected core and damage in insulation.
The content of the invention

The insulating barrier in outside；Each layer twisted wire is in opposite direction when the strand that conductor in core is used is twisted again, and adjacent layer is opposite.
It is preferred that, its lay ratio ≯ 20 of bundle strand conductor；The beam of multiple stranded conductor is closed in lay ratio ≯ 25, stranded lay ratio
Layer ≯ 16, outer layer ≯ 14.
It is preferred that, the cable core isolation strip is high-temperature polyester band, and the cable core isolation strip is by double-deck high-temperature polyester band structure
Into.
It is preferred that, the oversheath is made up of crosslinked polyolefin materials.
It is preferred that, it is described to be filled with the elastomer-filled thing of poly- silica.
It is preferred that, the electro-magnetic screen layer is aramid fiber yarn braid or annealed copper silk braid, and its count is not small
In 85%.
It is preferred that, separation layer is provided between the oversheath and electro-magnetic screen layer.
It is preferred that, the separation layer is watertight insulation, and the watertight insulation partly leads waterstop and outer layer by internal layer
Common waterstop constitute.
It is preferred that, the separation layer is non-woven fabrics.
It is preferred that, it is additionally provided between the oversheath and the separation layer or between separation layer and electro-magnetic screen layer some
Root fibre bundle strengthens rope, and the fibre bundle is strengthened rope and is evenly arranged along the periphery of the separation layer or electro-magnetic screen layer.
The beneficial effects of the utility model are：
The cable of the design can be used in all kinds of mobile electrical equipment under electromagnetic wave complex jamming environment, it is desirable to
Cable used has the interference of resistance external electromagnetic ripple in the process of running, it is ensured that the various current signals of transmission are safe and steady
It is fixed and reliable without producing distortion, the simultaneously effective safe operation of protection electric equipment, and its intensity is high, pull resistance is good, tool
It is standby soft, be not easily broken, the advantages of service life is long.
