Abstract
The present utility model discloses an acid and alkali corrosion resistant fluoroplastic insulation fluoroplastic sheath control cable. The cable comprises a core group composed of a plurality of cores, the periphery of the core group is provided with a belting, the outer surface of the belting is provided with an inner sheath, and each core comprises a core conductor and an insulation layer from the inside to the outside. The cable is characterized in that the periphery of the inner sheath is provided with a copper strip shield or a steel-tape armoring, the periphery of the copper strip shield or the steel-tape armoring is provided with an outer sheath, and the insulation layer, the inner sheath and the outer sheath are all formed by extruding fluorinated ethylene propylene material. The copper strip shield is formed by lapping 0.05-0.01 mm soft copper strips in an overlapping way, and the copper strip lapping overlap rate is not less than 15%. As the fluorinated ethylene propylene material is adopted to make the insulation layer, the inner sheath and the outer sheath, the insulation performance is increased, the acid and alkali corrosion resistance is realized, the service life of the cable is prolonged, and the application range of the cable is broadened. Moreover, the cable has good shielding performance, and is high temperature resistant and cold resistant.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of acid-alkali-corrosive-resisting fluoroplastic insulation fluoroplastics sheath control cable.
Background technology
Control, signal wires cable are as the connecting line between each electric appliances, instrument and the automatics; Be mainly used in important events such as control loop and protection circuit; Play various effects such as transmitting control, signal, be widely used in enterprises such as industrial and mineral, electric power, traffic, petrochemical industry.Because some chemical industry and special occasions contain acid or contain alkali etc.; Medium-sized electric wire acid-alkali-corrosive-resisting poor performance; Can not adapt to bad working environment; The useful life of cable is short, has brought very big hidden danger for the equipment safety operation of cable, influences the normal operation of electrical control equipment, electric power system and the safety of personal property.
At present, the poor performance of the acid-alkali-corrosive-resisting of many cables can not adapt to bad working environment, has had a strong impact on the useful life of cable.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is the acid-alkali-corrosive-resisting fluoroplastic insulation fluoroplastics sheath control cable that provides a mass good, safe and reliable.
To achieve these goals, the technical scheme below the utility model adopts:
Acid-alkali-corrosive-resisting fluoroplastic insulation fluoroplastics sheath control cable; Include the core group that a plurality of cores constitute; The periphery of core group is provided with band, and the outer surface of band is provided with inner sheath, and each core is to be made up of core conductor, insulating barrier from inside to outside successively; It is characterized in that: the periphery of said inner sheath is provided with copper strips shielding or steel-tape armouring, and the periphery of said copper strips shielding or steel-tape armouring is provided with oversheath; Said insulating barrier, inner sheath and oversheath all are to adopt the perfluoroethylene-propylene material to extrude to form.
The thickness of said insulating barrier is between 0.3～0.5mm.
Be provided with filler between said a plurality of core, said filler is a non-absorbent material.
Said copper strips shielding is to adopt the soft copper overlap of strips of 0.05～0.10mm wrapped, and the wrapped rate of putting up of copper strips should be not less than 15%.
The beneficial effect of the utility model: because insulating barrier, inner sheath and oversheath have adopted the perfluoroethylene-propylene material; Insulation property have not only been improved; But also have the characteristic of acid-alkali-corrosive-resisting, thus prolonged the useful life of cable, widened the range of application of cable; The utility model also has the characteristics of advantages of good shielding performance, high temperature resistant, cold-resistant, energy-conserving and environment-protective.
