Abstract
The utility model relates to a high-flame retardant, oxygen-isolating and fire-protecting power cable, which belongs to the technical field of a cable. The utility model is formed in a mode that the utility model is cabled by a wire core provided with two layers of refractory layers lapped with mica tapes and two layers of insulation layers, and two layers of lapping layers with high-flame retardant glass-fabric tapes, an oxygen isolating layer with embossing copper tapes, an oversheath, etc. are arranged on the cable core. Double layers of refractory layers are lapped on the external surface of a conductor, and insulation layers lapped by high-fire retardant glass-fabric tapes are arranged on the double layers of refractory layers. Extruded insulating layers of cross-linked polyethylene are squeezed on the insulation layers lapped by high-fire retardant glass-fabric tapes, and double layers of lapping layers with high-fire retardant glass-fabric tapes are lapped on the cable core. Fillers are arranged in gaps among the cable core and high-fire retardant glass-fabric tapes, oxygen isolating layers with longitudinal wrapping and embossing copper tapes are arranged on double layers of lapping layers, and the oversheath is arranged on the oxygen isolating layer with embossing copper tapes. The utility model has the advantages of reasonable and simple structure, easy production manufacture, low cost, smooth, round and normal appearance of the utility model, good service performance and safe use. The utility model satisfies fire-protection requirements of places aggregating with people such as underground railways, commercial buildings, etc.
Description
Technical field
The utility model relates to a kind of novel fire electricity line structure, belongs to the cable technology field.
Background technology
Along with development and national economy, subway, power station, hospital, skyscraper and various public place of entertainment are more and more higher to the requirement of fire prevention, fire-fighting, in case these place breaking out of fires need in time to withdraw rapidly the crowd, rescue visual plant, and carry out fire-fighting work.Existing fire-fighting fire-resisting cable is by the flame retardant coating on conductor and the conductor, formation such as insulating barrier and oversheath, when breaking out of fire, though can make control, electric power, video display, the circuit of systems such as guiding and alarm is kept the some time, but keep the time requirement that the operating time does not all reach national Specification, main is all to adopt the Halogen fire proofing for improving flame retardant effect, thereby also cause and in burning, understand release macro-corrosion gas and dense smoke, the heavy corrosion instrument and equipment, jeopardize personal safety more, also can give simultaneously and withdraw evacuation, the fire-fighting rescue personnel brings very big difficulty.
The utility model content
The purpose of this utility model is to overcome the deficiency that existing cable exists, provide a kind of and have high temperature resistant, good insulation preformance, puncture voltage height, heat-resistance index is big, shield effectiveness good, the fire-resistant oxygen barrier of high flame retardant, and nontoxic non smoke, high flame retardant oxygen barrier fire-fighting power cable that light transmittance is high.
The purpose of this utility model is to realize like this, high flame retardant oxygen barrier fire-fighting power cable, comprise flame retardant coating, insulating barrier and oversheath on conductor and the conductor, it is characterized in that being provided with double-deck lapping layer of high flame retardant glass fibre belt and embossing copper strips oxygen barrier layer by the cable core of the core stranding that is provided with wrapped double-deck flame retardant coating of mica tape and dielectric layers; Double-deck flame retardant coating is wrapped at the conductor outer surface, high flame retardant glass fibre belt lapped insulation layer is set on double-deck flame retardant coating, extruded cross-linking polyethylene extruded insulation layer on high flame retardant glass fibre belt lapped insulation layer, the double-deck lapping layer of high flame retardant glass fibre belt is wrapped on cable core, be provided with inserts in the space between cable core and high flame retardant glass fibre belt, vertical bag embossing copper strips oxygen barrier layer is set on double-deck lapping layer, and oversheath is arranged on the oxygen barrier layer.
Described conductor is the high-quality copper free wire, and cross-sectional area of conductor is greater than 10mm
2Be the stranded round conductor of multiply high-quality copper free wire concentric type.The wrapped double-deck flame retardant coating of mica tape is two-sided synthetic mica tape, wrapped Duplication 〉=40%.Described inserts is a high flame retardant glass rope.The seam of the embossing copper strips of the vertical bag of oxygen barrier layer is that continuous welding connects.Oversheath is extruded in embossing copper strips oxygen barrier layer outer surface for the high flame retardant polyolefine material.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, cable smooth in appearance rounding, and serviceability is good.Core adopts double-deck fire-resistant and two-layer insulation, double-deck wrapped and copper-clad band oxygen barrier are set on the cable core, guaranteed that cable has high temperature resistant, good insulation preformance, puncture voltage height, heat-resistance index is big, shield effectiveness is good characteristics, under the situation of breaking out of fire, cable has the fire-resistant oxygen barrier of high flame retardant, nontoxic non smoke, light transmittance be up to 85%, helps that personnel withdraw evacuation, the fire fighter puts out a fire and rescues trapped personnel and property, reduces loss as far as possible.This cable, according to the fire-resistant experimental standard IEC 60331:1999 of country, 750 ℃ flames are sprayed on carry out combustion experiment on the cable, reach the specified standard requirement fully, satisfy the place use that personnel assemble fire-fighting, as underground railway, commercial building, comprehensive office intelligence building, hotel, exhibit halls, naval vessel, boarding lounge, station terminal, automation control centre, exchange room, computer center etc.Safe in utilization, excellent popularization using value and vast market prospect are arranged.
