Abstract

The invention relates to a nuclear electromagnetic pulse resisting cable which structurally comprises a conductor, an insulator, a separated shield part, a combined shield part and a protection sleeve. The high-temperature-resisting fluoroplastic insulator extruded by high-temperature extruding equipment is arranged at the periphery of the conductor using a tin-plated round copper stranded wire or a sliver-plate round copper stranded wire, the separated shield part woven by high-weaving tin-plated round copper wires is arranged at the periphery of the high-temperature fluoroplastic insulator, the combined shield part formed by a control line and a data line which are stranded by a cabling machine is positioned at the periphery of the separated shield part, and the low-temperature-resisting elastic protection sleeve extruded by a normal-temperature extruding machine is positioned outs of the combined shield part. Manufacturing process uses a combined method of lapped shield and braided shield and primarily uses 300T conductive cloth lapping materials to substitute metal lapping materials. The nuclear electromagnetic pulse resisting cable has the advantages of resisting to nuclear electromagnetic pulse, being soft, being high in abrasion resistance, preventing mould, resisting to moist, resisting to acid-base corrosion, being capable of keep good data transmission performance in complex electromagnetic environment, being applied to a hydraulic information control system and having the information transmission function in special portions of the hydraulic information control system.
