Abstract
The utility model discloses an insulating high-temperature-resistant cable. An insulating layer is extruded on one or a plurality of twisted tinned copper conductors, so as to form an insulating wire core; three insulating wire cores are stranded and are in turn wrapped by a wrapping tape layer and a soft copper aluminum compound tape shielding layer, so as to form a main wire core; five main wire cores are combined and are wrapped by a polyurethane wrapping tape layer; the polyurethane wrapping tape layer is wrapped by a tinned copper wire braided layer in a longitudinal manner; an outer sheath layer made of a polyethersulfone PES extrusion material is extruded outside the tinned copper wire braided layer; a plurality of drainage wires made of tinned copper wires are arranged between the polyurethane wrapping tape layer and the shielding layer; five torsion resistant nylon wire cores are not arranged among the five main wire cores; and the center of the cable is provided with a center wire core. The insulating high-temperature-resistant cable of the utility model is resistant to high temperature, resistant to flame, resistant to acid, resistant to alkali chemical reagent, resistant to interference, is environmentally friendly, and has the excellent electrical and mechanical properties.
Description
technical field
The utility model relates to a kind of insulation high-temperature-resistant cable, belongs to technical field of electric wires and cables.
background technology
Power cable (power cable), for transmitting and distribute the cable of electric energy.Be usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power power, comprising 1-500KV and above various electric pressure, the power cable of various insulation.
utility model content
The utility model provides a kind of insulation high-temperature-resistant cable, and high temperature resistant, water-fast steam, fire-retardant, acid and alkali resistance chemical reagent, environmental protection, anti-interference have superior electrical performance and mechanical performance simultaneously.
Scheme of the present utility model is as follows: a kind of insulation high-temperature-resistant cable, on single or many stranded tinned copper conductors, extruded insulation layer forms insulated wire cores, and after three insulated wire cores are stranded, wrapped belting layer, soft copper aluminum composite belt screen taking flame-resistant high-temperature-resistant glass-fiber-fabric as material forms master core successively; Wrapped polyurethane belting layer after five master core combinations, described polyurethane belting layer is vertical bag tincopper fuse wire braided armor outward, and described tincopper fuse wire braided armor extrudes polyether sulfone PES outward and extrudes the external sheath layer that material is made; The drainage thread that many tinned copper wires form is set between described polyurethane belting layer and screen; Five antitorque nylon cores that draw are not set between five described master cores; Cable center arranges center core, and described center core is made up of two stranded rear wrapped belting layers taking flame-resistant high-temperature-resistant glass-fiber-fabric as material of insulated wire cores.
Further, described insulating barrier adopts polyether sulfone PES to extrude material to make.
The utility model structural design is simple, scientific and reasonable, manufactures easily, and cable insulation and oversheath adopt polyether sulfone PES, have effectively improved the serviceability of product; The utlity model has excellent heat resistance, physical and mechanical properties, electrical insulation capability, extrusion molding, particularly have can at high temperature use continuously with temperature environment jumpy in still retention is stable.
