Explosion-proof electric wire optical cable for offshore oil platform

Abstract

The invention discloses an explosion-proof electric wire optical cable for an offshore oil platform. The explosion-proof electric wire optical cable comprises a copper core, a first steel strip general shielding layer, a first steel belt armor, a folding groove, a second polyvinyl chloride insulation wrapping tape, a second steel belt armor, a tightening hoop, a fixed screw and a protective film,wherein a copper strip sub shielding layer is wrapped on the outer side of the copper core, and a first polyvinyl chloride insulation wrapping tape is pressed on the outer side of the copper strip subshielding layer; one end of the second steel strip armor is fixedly connected to the left side of the folding groove, and the other end of the second steel strip armor is embedded in a notch; the tightening hoop is arranged on a polyvinyl chloride sheath; the fixed screw is arranged on the tightening hoop; and the protective film wraps the outer surface of the polyvinyl chloride sheath. The optical cable provided by the invention has high anti-electrical signal and magnetic signal interference capability, and meanwhile, the explosion-proof capacity of the cable is greatly improved; and in addition, the cable is convenient to cut and store, so that the practicability of the cable is greatly improved.

Description

technical field [0001] The invention relates to the field of optical cables and cables, in particular to an explosion-proof electrical and optical cable for offshore oil platforms. Background technique [0002] With the development of society, wires and cables are used more and more widely, and there are more stringent and diverse requirements for the performance of wires and cables. Continuously improving the performance of sheath materials is an urgent need for economic and social development. Explosion-proof wires and cables are in Some places with explosive hazards have been widely used. For example, in warehouses, chemical companies, gas stations, gas stations, oil companies and other places with high safety requirements, explosion-proof wires and cables are required to meet the safety requirements of these places. sexually demanding. [0003] This involves an explosion-proof wire and cable for offshore oil platforms. At present, the explosion-proof structure of the ex...
