High electromagnetic pulse prevention flexible aluminum alloy cable and cable manufacturing method

Abstract

The invention relates to a high electromagnetic pulse prevention flexible aluminum alloy cable. The cable comprises a cable conductor, wherein the cable conductor is formed through twisting multiple strands of alloy wires, an outer side of the cable conductor is extruded by a foaming thermoplastic elastomer insulation layer, an outer side of the foaming thermoplastic elastomer insulation layer is wrapped into a semi-conduction strap wrapping shielding layer, the foaming thermoplastic elastomer insulation layer and drainage wires are twisted, the foaming thermoplastic elastomer insulation layer and an outer side of the drainage wires are longitudinally covered by a conductive strap, an inner surface of the conductive strap is connected with multiple strands of drainage wires, an outer side of the conductive strap is provided with a nickel-clad copper wire woven shield layer, an outer side of the nickel-clad copper wire woven shield layer is extruded by a foaming thermoplastic elastomer sheath, and an outer side of the foaming thermoplastic elastomer sheath is extruded by a stainless band linkage armor layer. The cable is advantaged in that low manufacturing cost, excellent performance, good electromagnetic pulse prevention effect, simple manufacturing process, novel design, strong practicality, good stability, high reliability, convenient use and easy popularization and application are realized.

Description

technical field [0001] The present invention relates to a cable with high resistance to electromagnetic pulse, in particular to a flexible aluminum alloy cable with high resistance to electromagnetic pulse, and also relates to a cable manufacturing method. The flexible aluminum alloy cable with high resistance to electromagnetic pulse is suitable for detection instruments under strong electromagnetic interference that often move Connections between precision equipment such as electric power and control systems. Background technique [0002] In order to achieve high-precision detection results, precision detection instruments have very high requirements for the protection level of related facilities. Cables play the role of signal and power transmission, and their shielding effect is particularly important. For detection instruments that are frequently moved or temporarily placed , the cable must meet the requirements of anti-electromagnetic interference, softness and light w...

Problems solved by technology

[0003] Existing conventional cables are in the form of copper conductors, copper wire shielding or copper wire plus alloy tape shielding. The cable bending performance is poor and the cable is heavy, especially in the occasions where the cable needs to be retracted frequently. Dragging and dropping the sheath in such harsh environments is very easy to damage, which affects the service life of the cable
