Abstract
The invention relates to a high temperature-resistant cable, and belongs to the technical field of cables. The cable comprises a cable core and an outer sheath, wherein the cable core is formed by stranding a plurality of insulated wire cores; glass cords are filled in the gaps of the cable core; a dual-layer glass tape wrapping layer wraps on the cable core; a composite aluminum-plastic tape wraps on the wrapping layer; a tetrafluoroethylene-ethylene copolymer inner sheath layer is extruded on the composite aluminum-plastic tape; a steel tape armored layer wraps on the inner sheath layer; a fluorinated ethylene propylene plastic outer sheath layer is extruded out of the armored layer; and the insulated wire core is formed by extruding the tetrafluoroethylene insulating layer on the surface of a tinned copper wire conductor. The high temperature-resistant cable is reasonable and compact in structure, easy to produce and manufacture, low in cost, round in appearance, used safely, and suitable for transmission line installation in the construction of large-scale projects such as power plants, petrochemical industries, metallurgy, iron and steel and high-rise buildings in a high-temperature environment.
Description
Technical field
The present invention relates to a kind of high temperature-resistant cable structure, belong to the cable technology field.
Background technology
Along with the high speed development of iron and steel, the energy, petrochemical industry, electric power, existing crosslinked polyetylene insulated layer by conductor and conductive surface and oversheath etc. constitute cable, and be poor owing to resistance to elevated temperatures, can not adapt to the requirement of iron and steel, oil, space flight etc.The used cables of industry such as iron and steel, petrochemical industry, metallurgy because for a long time at high temperature under the condition, therefore, require high to the resistance to elevated temperatures of cable.In the past, often, brought very big loss to the country and people because of the situation of cable shortage resistance to elevated temperatures breaking out of fire accident.In the engineering constructions such as fossil oil, iron and steel, chemical industry, need the cable of usefulness more and more in modern times, so the fire resistant electric wire cable of market demand excellent performance is also more and more.
Summary of the invention
The object of the invention is exactly for satisfying the needs in market, a kind of fire-retardant, corrosion resistant high temperature-resistant cable that has being provided.
The objective of the invention is to realize like this; A kind of high temperature-resistant cable comprises cable core and oversheath by many insulated core stranding, it is characterized in that filled glass fiber rope in the gap of said cable core; Wrapped double glazing silk ribbon lapping layer on the cable core; Wrapped aluminium-plastic tape on lapping layer extrudes the tetrafluoroethylene-ethylene copolymer sheath on the aluminium-plastic tape, wrapped steel-tape armouring layer on the sheath; Outside armour, extrude the polyfluorinated ethylene plastic oversheath, said insulated wire cores extrudes the teflon insulation layer by the tinned copper wire conductive surface and constitutes.
Described aluminium-plastic tape is a copolymer type single face aluminium-plastic tape.
The present invention is simple and reasonable, compact, manufactures easily, and cost is low, and the profile rounding is safe in utilization.Cable has less insulation dielectric loss and good shielding properties and good heat aging property.Cable has stronger resistance to elevated temperatures and insulation property, fire resistance, decay resistance; Can satisfy the performance requirement with cable of modernization project in building, be applicable to the transmission line installation under the hot environment in the construction of heavy constructions such as power plant, petrochemical industry, metallurgy, iron and steel, skyscraper.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 conductor, 2 insulating barriers, 3 glass cords, 4 glass tape lapping layers, 5 aluminium-plastic tapes, 6 sheaths, 7 armours, 8 oversheaths.
Embodiment
Extrude teflon insulation layer 2 on tinned copper wire conductor 1 surface and constitute insulated wire cores.By filled glass fiber rope 3 in the gap of the cable core of many insulated core stranding; Wrapped double glazing silk ribbon lapping layer 4 on the cable core; Wrapped copolymer type single face aluminium-plastic tape 5 on lapping layer; Extrude tetrafluoroethylene-ethylene copolymer sheath 6 on the aluminium-plastic tape, wrapped steel-tape armouring layer 7 extrudes polyfluorinated ethylene plastic oversheath 8 on the sheath outside armour.
