Abstract
The utility model relates to a special high-temperature-resistant cable, which comprises insulating layers arranged inside an inner conductor and outside the inner conductor. The insulating layers are irradiation cross-linked fluororubber insulating layers. The special high-temperature-resistant cable has the advantages that the temperature of the cable can reach 250 DEG C at least, the temperature of the cable in long-term usage is 250 DEG C, the temperature of the cable in short-term usage can reach 300 DEG C, the long-term operating temperature of the cable can reach -40 DEG C, the special high-temperature-resistant cable is much softer than a cable made of common fluorine plastics, brings convenience for users during processing and using, is simple in processing technique, high in flame resistance and excellent in mechanical performance, greatly reduces production difficulty and cost and has oxygen index reaching 40, brute force commonly matched with the fluororubber ranges from 10MPa to 20MPa, the elongation at rupture of the fluororubber ranges from 150% to 350%, and tearing resistance of the fluororubber ranges from 3KN/m to 4KN/m.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of special high temperature-resistant cable that is used for field extensive uses such as Aero-Space, rolling stock, the energy, iron and steel, non-ferrous metal metallurgy, oil exploitation, motor.
Background technology
Along with Aeronautics and Astronautics and electronics industry, and the develop rapidly of defence engineering, cable is proposed higher requirement, cable develops to direction such as soft, high temperature resistant.General high temperature resistant wire adopts fluorine materials such as perfluoroethylene is third rare, polytetrafluoroethylene as insulating material, so this series products is that fluorine material whole cable is harder owing to what adopt, pliability is not enough, can not satisfy the frequent alternating bending of user, mobile instructions for use.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of high temperature resistant, soft special high temperature-resistant cable.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of special high temperature-resistant cable, the insulating barrier that is included conductor and be provided with outside inner wire is characterized in that: described insulating barrier is a cross-linking radiation fluorubber insulated with material layer.
The beneficial effects of the utility model are: 1, high temperature resistant: because the fluorubber insulating material, the heatproof of this kind material all can reach more than 250 ℃, and long-term serviceability temperature continuously is 250 degree, and the short-term serviceability temperature can reach 300 ℃; Low temperature resistant: the temperature that works long hours can reach-40 ℃.2, softness: because the hardness of fluorubber material generally has only 80A, than common fluoroplastics softness make things convenient for the user to process use more.3, processing technology is simple: traditional rubber generally adopts the mode of steam vulcanization (cure) to process to improve the intensity of insulation, existing irradiation fluorubber material only needs electron accelerator to carry out irradiation processing can realize the cross-linking modified of material, greatly reduce production difficulty and cost 4, good flame resistance: have very high anti-flammability, oxygen index can reach 40.5, mechanical performance is good: the general brute force that cooperates of fluorubber is between 10 ~ 20MPa, and elongation at break is between 150 ~ 350%, and tearing toughness is between 3 ~ 4KN/m.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, special high temperature-resistant cable, the insulating barrier 2 that is included conductor 1 and be provided with outside inner wire 1, insulating barrier 2 are cross-linking radiation fluorubber insulated with material layer.
The utility model can obtain by following technical process manufacturing: with stranding machine the stranded multiply of bunching machine is silver-plated or the nickel plating monofilament as inner wire 1, extrude insulating barrier 2 at inner wire 1 external application Rubber Extruder, insulating barrier 2 adopts the fluorubber material, and then pass through electron accelerator and carry out irradiation processing, general irradiation dose is that 10Mrad～15Mrad can realize the crosslinked of material molecule structure.
Claims (1)
