Embodiment 1

[0038] Such as image 3 , a flexible anti-nuclear reinforced cable, including a central frame 2, a cable core unit 1, a polyester wrapping layer 3, a shielding layer, and a polyurethane sheath layer 8 from the inside to the outside, the central frame 2 is made of TPEE material and the cable core unit 1 are respectively isolated in the wrapping space of the wrapping layer 3 . The number of cable core units 1 is four, and the cross-section of the central frame 2 is cross-shaped. The cable core units 1 are respectively placed on the four corners of the central frame 2 to be isolated, and the wrapping layer 3 is made of a transparent polyester tape material with a thickness of 0.03mm. , the shielding layer from the inside to the outside is the first silver-plated copper braid layer 4, the copper-nickel alloy cloth tape wrapping layer 5, the nickel-iron alloy tape wrapping layer 6, and the second silver-plated copper braid layer 7. Multi-layer shielding is used to shield the elect...

Embodiment 2

[0061] On the basis of Example 1, the central frame 2 is replaced with TPU material, the number of cable core units 1 is eight and the cross-section of the central frame 2 is a rice-shaped structure, and the cable core units 1 are independently separated by rice sub-frames. Its preparation steps also carried out parameter adjustment on the basis of embodiment 1:

[0062] Step 1: Make the cable core unit, twist the prepared thirteen-core insulated core wires and the twisted structure is 3 cores inside and 10 cores outside, and wrap a layer of polyester film tape on the outer layer synchronously after twisting A cable core unit is manufactured, and the outer diameter of the obtained cable core unit is about 4.2 mm.

[0063] Step 2: Assemble the cable, install the cable core unit cable tray symmetrically on the cable forming machine, install the central frame cable tray at the center of the cable forming machine, and then distribute the cable core units at each corner of the cent...

Embodiment 3

[0071] On the basis of Example 1, the central frame 2 was replaced by rubber material. After bending 3000 times through experiments, the performance of the cable did not change significantly in all aspects, which met the requirements for the use of the cable.

Abstract

The invention relates to a flexible anti-nuclear reinforced cable and a manufacturing method. The flexible anti-nuclear reinforced cable comprises a central skeleton, cable core units, a polyester wrapping layer, a metal shielding layer and a polyurethane sheath layer from inside to outside, and is characterized in that the central skeleton is arranged at the central position of the cable, is madeof a thermoplastic elastomer material and isolates the cable core units in the wrapping space of the wrapping layer. The flexible anti-nuclear reinforced cable solves the problems that an existing anti-nuclear electromagnetic pulse cable is poor in flexibility, a cable conductor is broken and disengaged due to the fact that the bending portion of the cable is uneven in stress, and the using requirement for the flexible anti-nuclear electromagnetic pulse cable in a nuclear weapon cannot be met.

Description

technical field [0001] The invention belongs to the field of cables, in particular to the field of anti-nuclear electromagnetic pulse reinforced cables. Background technique [0002] The existing flexible anti-electromagnetic pulse cables are mainly composed of multi-layer metal braiding and composite film wrapping shielding. This flexible anti-electromagnetic pulse cable mainly realizes the overall flexibility of the cable by improving the flexibility of the shielding material. For example, the shielding material adopts Soft conductive cloth or wire braided construction. The core wires of this kind of cable are mainly arranged in a regular manner. During the bending process, the core wires of each layer are squeezed against each other, and the core wires of the inner layer will be squeezed by the outer circle of core wires. During the bending process in the harsh outdoor environment, the cable has to withstand a very small bending radius, and the number of bending times ca...
