Abstract
The utility model relates to a high-temperature-resisting signal cable including core wires formed by arranging insulating layers, shielding layers and inner sheath layers outside conductors successively. The high-temperature-resisting signal cable also includes a taped covering, a fire-resisting layer and an outer sheath layer. The wire cores are coiled with the taped covering. The taped covering is coiled with a fire-resisting layer. The outer sheath layer is extruded outside the fire-resisting layer. The high-temperature-resisting signal cable provided by the utility model has beneficial effect of high temperature resistance, low temperature resistance, wide application range and good fire resistance.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of high temperature resistant signal cable.
Background technology
Along with the develop rapidly of Aeronautics and Astronautics and electronics industry and defence engineering and metallurgy industry, to the higher high temperature resistant requirement of cable proposition of signal transmission usefulness.Present employed cable exists weak point aspect high temperature resistant, when cable easy breaking out of fire during in excess load or short circuit, usually brings about great losses to people's lives and properties.General high temperature resistant signal cable adopts perfluoroethylene third rare fluorine material that waits as insulating material, and high-temperature resistant is 250 ℃, can not satisfy the heatproof requirement of user Geng Gao.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of high temperature resistant signal cable.
The utility model for achieving the above object, the technical scheme that adopts is: a kind of high temperature resistant signal cable, it is characterized in that: be included in the heart yearn that insulating barrier, screen, inner restrictive coating that conductor is provided with successively consist of outward, also comprise lapping layer, flame retardant coating, external sheath layer, several described heart yearns twine one deck lapping layer outward, outside lapping layer, twine one deck flame retardant coating, extrude one deck external sheath layer at flame retardant coating.
The beneficial effects of the utility model are:
1, high temperature resistant: because insulating barrier has adopted the polytetrafluoroethylmaterial material of fire resistant anticorrosive, lapping layer adopts polytetrafluoroethylene film, and flame retardant coating adopts the good fire-resistant isinglass belt of fire protecting performance, and the heatproof of polytetrafluoroethylene and mica tape material all can reach 500 ℃.This cable has advantages of fabulous fire resistant anticorrosive, keeps good stability under the adverse circumstances such as high low temperature, oil, alkali, acid, water.
2, low temperature resistant: polytetrafluoroethylene and mica tape material, the temperature that works long hours can reach absolute zero.
3, the scope of application is wide: the long-term working temperature that allows of cable is-140 ℃---+380 ℃, can be widely used in the signal transmssion line that the industries such as oil, metallurgy, electric power, chemical industry, papermaking are made electrical instrumentation and automation control system.
4, good flame resistance: because multilayer material all adopts inorganic material, so cable has very high fire protecting performance.Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high temperature resistant signal cable, be included in insulating barrier 1-2, the screen 1-3 that conductor 1-1 is provided with successively, the heart yearn 1 that inner restrictive coating 1-4 consists of outward, also comprise lapping layer 2, flame retardant coating 3, external sheath layer 4, several heart yearn 1 outer winding one deck lapping layers 2, at lapping layer 2 outer winding one deck flame retardant coatings 3, extrude one deck external sheath layer 4 at flame retardant coating 3.
Screen 1-3 is the copper strip shielding layer, and inner restrictive coating 1-4 is cross-linking radiation ethylene-tetrafluoroethylene inner restrictive coating.
Insulating barrier 1-2 adopts polytetrafluoroethylmaterial material.
Flame retardant coating 3 adopts fire-resistant isinglass belt.
The utility model can obtain by following technical process manufacturing: use the zinc-plated monofilament copper cash of electric wire wire drawing machine as conductor 1-1, outside conductor 1-1, use the high temperature extruder to extrude insulating barrier 1-2, then twine copper strip shielding layer 1-3 by the cable winding machine, then use extruder to extrude inner restrictive coating 1-4 and consist of heart yearn 1,7 heart yearns are by interior 1, peripheral 6 arrangements assemble the cable conductor structure, twist together and consist of the heart yearn group, the heart yearn group is twined polytetrafluoroethylene film simultaneously consist of lapping layer 2 and fire-resistant isinglass belt formation flame retardant coating 3 on Horizontal lapping device, extrude external sheath layer 4 at the high temperature extruder at last, consist of whole high-temperature resistant anti-corrosive cable.
Execute routine conductor 1-1 and adopt the 0.41mm tinned wird; The present embodiment insulating barrier 1-2 adopts FEP 101 materials of Daikin company; Screen adopts bare copper strip to twine, and the present embodiment screen 1-3 adopts the bare copper strip of wide 12mm, thick 0.2mm.
