Ultrasoft control cable resistant to nuclear electromagnetic pulses

Abstract

The invention discloses an ultrasoft control cable resistant to nuclear electromagnetic pulses. The ultrasoft control cable comprises conductors, each conductor is wrapped by an insulating layer to form an insulating wire core, the multiple insulating wire cores and a filled core formed by intertwisting micropore polytetrafluoroethylene belts are intertwisted together to form a cable core, a composite metal shielding layer is woven outside the cable core and sequentially comprises a copper-nickel alloy woven belt wrapping layer, a tinned copper braid, a polytetrafluoroethylene micropore belt wrapping layer, an iron-nickel alloy belt wrapping layer and a nickel plated copper wire braid, and the composite metal shielding layer is wrapped by an outer sheath. The ultrasoft control cable is small in outer diameter, light in weight, resistant to high and low temperature, and resistant to flame and weather, the outer diameter and the weight of the cable are effectively reduced, the shielding effectiveness can be improved to 82.9 dB from original 70 dB, and the softness of the cable is improved.

Description

Technical field: [0001] The invention relates to the technical field of weapon system control, in particular to an ultra-soft anti-nuclear electromagnetic pulse control cable. Background technique: [0002] With the rapid development of electronic technology, the strength of electronic countermeasures and information countermeasures in modern warfare determines the success or failure. Modern special equipment systems have highly used microelectronic program control, and microelectronic program control systems are extremely vulnerable to interference from external strong electromagnetic fields. And it is destroyed, so the electromagnetic protection of the system is particularly important, which is related to the safety of the system. The most deterrent strategic weapon in modern times is the high-energy pulsed electromagnetic field produced by nuclear weapons. When a nuclear weapon explodes, a considerable part of its energy is released in the form of electromagnetic pulses, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the shielding layer of anti-nuclear electromagnetic pulse cables at home and abroad is generally composed of a layer of soft magnetic alloy tape, multi-layer metal tape wrapping and multi-layer wire braiding. Disadvantages: In field use, the soft measuring alloy belt often scratches or breaks the wire core, resulting in a short circuit of the cable or a decrease in the performance of the anti-nuclear electromagnetic pulse, which cannot meet the requirements of flexible and weight-reducing cables for field maneuvers.
