Background
The shielding structure of the anti-nuclear magnetic pulse cable in the existing market is mostly a mode of wholly wrapping a metal strip material behind an insulation core total stranded cable, and because the metal strip material is overlapped around the package, the shielding layer can be formed into a cylindrical shape after the overlapping, the flexibility is poor under the bending condition, and the metal strip material is heavy around the package overlapping, so that the shielding structure is not beneficial to the operation between equipment.
Disclosure of Invention
In view of the situations that the flexibility is poor and the weight of the product is heavier to be unfavorable for the operation of linking between devices due to the structure of the existing nuclear magnetic pulse resistant cable in the current market, the utility model provides the flexible nuclear magnetic pulse resistant cable which can keep the advantages of good flexibility and light overall weight of the cable on the premise of meeting the performance requirement of nuclear magnetic pulse resistance.
In order to achieve the purpose, the utility model adopts the technical scheme that: a soft nuclear magnetic pulse resistant control cable comprises a shielding single wire, a ground wire, an electromagnetic shielding layer, an outer shielding layer and an outer sheath;
a ground wire is added into the plurality of shielding single wires to form a cable core, and an anti-electromagnetic shielding layer, an outer shielding layer and an outer sheath are sequentially arranged outside the cable core;
the shielding single line is formed by sequentially arranging an insulating layer and an inner shielding layer outside a conductor.
The utility model has the beneficial effects that: the conductor and the ground wire are made of tinned copper wires which have good weldability and corrosion resistance and high conductivity.
The insulating material adopts fluorinated ethylene propylene which has excellent electrical insulating property and high temperature resistance grade which can reach 200 ℃, and effectively prevents insulating shrinkage during welding.
The sub-shielding layer adopts tin-plated copper-clad steel alloy, and has the advantage of weight reduction.
The total shielding layer adopts a weaving combination form, different metal materials are compounded to form a plurality of shielding reflection interfaces, the shielding efficiency of the cable can be improved, the alloy wires are adopted to replace alloy belts, the flexibility is increased, and the cable is easy to bend when in use. The high-permeability alloy wire has high permeability and plays a role in shielding at a low frequency, and meanwhile, compared with a common tinned copper wire, the tinned copper clad steel has the characteristics of low density and light weight, and the weight of the cable can be reduced while the performance is ensured.
The sheath adopts TPR elastomer, has better mechanical environment performance, and is wear-resisting and soft.
The cable has the advantages of good insulating property, high voltage resistance, flexibility, 5 times of cable outer diameter of the minimum bending radius, 70dB of nuclear electromagnetic pulse resistance, and good transmission performance and nuclear electromagnetic resistance.
The cable has excellent signal transmission and control performance, and adopts advanced materials to carry out wrapping and weaving alternate structure, so that the cable also has excellent nuclear magnetic resistance under the condition of strong interference, and is soft, light in weight and easy to use.
