Zusammenfassung: | The utility model relates to a measuring controlling cable for explosion prevention for an oil and gas pipeline, which belongs to the technical field of a cable. The utility model is provided with a plurality of cable cores cabled by wire groups pair-twisted by two insulated cores, compound shielding layers are arranged on the wire groups, cabling lapping layers with high-flame retardant glass-fabric tapes are arranged on the cable cores, and fillers are arranged in voids of the cable cores. Total shielding layers with metal plastic tapes are lapped on the cabling lapping layers with high-flame retardant glass-fabric tapes, diversion wires are arranged among the cabling lapping layers with high-flame retardant glass-fabric tapes and the total shielding layers with metal plastic tapes, and lapping layers with high-fire retardant glass-fabric tapes are lapped on the total shielding layers with metal plastic tapes. Inner protecting layers of high-fire retardant polymer are extruded on the lapping layers with high-fire retardant glass-fabric tapes, steel-tape armours are arranged on the inner protecting layers of high-fire retardant polymer, and outer protecting layers of high-fire retardant nitrile composite are extruded on the steel-tape armours. The utility model has the advantages of reasonable structure, simplicity, compactness, easy production manufacture and low cost. The utility model has the characteristics of high-low temperature resistance, oil resistance, acid base resistance, strong electromagnetic interference and strong electrostatic interference prevention, low capacity, low inductance and high flame retardancy. The utility model satisfies the requirements of a cable for the oil and gas pipeline. |
