Abstract
The utility model discloses an insulated high-temperature-resisting power cable. An insulated wire core is formed by extruding an insulating layer on a single tinned copper conductor or a plurality of twisted tinned copper conductors; a cable core is formed by twisting a plurality of insulating wire cores; a high-temperature-resisting material is filled in the cable core to form a filled layer; a lapping layer, a longitudinal-wrapped shielding layer and an extruded sheath layer are sequentially arranged on the outer surface of the filled layer; and a drainage wire which is formed by a plurality of tinned copper wires is arranged between the lapping layer and the shielding layer. The insulated high-temperature-resisting power cable is resistant to high temperature, water vapor and acid and alkali chemical reagents, is flame-retardant, environment-friendly and interference-free, and is high in electrical performance and mechanical performance.
Description
Technical field
The utility model relates to a kind of insulation high-temperature-resistant power cable, belongs to technical field of electric wires and cables.
Background technology
Power cable (power cable) is for the cable of transmission and distribution 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.
The utility model content
The utility model provides a kind of insulation high-temperature-resistant power 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 power cable, and the extruded insulation layer consists of insulated wire cores on single or many stranded tinned copper conductors, consists of cable core by many eradications edge core twisted synthesizing cable; Fill exotic material in the described cable core and form packed layer, the outer surface of described packed layer is lapping layer, vertical bag screen and extrude restrictive coating successively; The drainage thread that many tinned copper wires consist of is set between described lapping layer and the screen.
Described insulating barrier and external sheath layer all adopt polyether sulfone PES to extrude material.
Described lapping layer is take the flame-resistant high-temperature-resistant glass-fiber-fabric as material, and described screen is the vertical bag of soft copper aluminum composite belt screen.
The beneficial effects of the utility model are:
1, structural design is simple, scientific and reasonable, manufactures easily, and cable insulation and oversheath adopt polyether sulfone PES, Effective Raise the serviceability of product.
2, cable 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of insulation high-temperature-resistant power cable, extruded insulation layer 2 consists of insulated wire cores on single or many stranded tinned copper conductors 1, consists of cable core by many eradications edge core twisted synthesizing cable; Fill exotic material in the described cable core and form packed layer 3, the outer surface of described packed layer 3 is lapping layer 4, vertical bag screen 6 and extrude restrictive coating 7 successively; The drainage thread 5 that many tinned copper wires consist of is set between described lapping layer 4 and the screen 5.
7 layers of described insulating barrier 2 and oversheaths all adopt polyether sulfone PES to extrude material.
Described lapping layer 4 is take the flame-resistant high-temperature-resistant glass-fiber-fabric as material, and described screen 6 is the vertical bag of soft copper aluminum composite belt screen.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
