Abstract
The utility model relates to a fluoroplastic insulating temperature-resistant anti-corrosion cable. A conductor of the cable is coated with FEP (fluorinated ethylene-propylene) insulating layers, asbestos cords are filled between the FEP insulating layers, and the FEP insulating layers and the asbestos cords are all wound by alkali free glass fiber strips. The alkali free glass fiber strip is coated with a shielding layer, and the shielding layer is coated with a FEP sleeve. Because of the insulating chemical property of FEP, the fluoroplastic insulating temperature-resistant anti-corrosion cable has advantages like good high temperature resistance, flame retardance, acid resistance, alkaline corrosion resistance and electric insulating property.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fluoroplastic insulation heatproof anti-corrosion cable.
Background technology
At present, along with the high speed development of China's industry, the electric automatization degree is in the popularization and application of every profession and trade, and plastic insulated cable constantly increases in the industrial scope of application and consumption, and some special factories and miness and industry also need to use a large amount of plastic insulated cables.But the plastic insulated cable of GB/T 9330 prescribed by standard also is not suitable for these special industries and some special environment occasions.The overload capacity and the short circuit thermal capacity of common plastics insulated cable (as the cable of models such as KVV, KYJV) are little, and the long-term work temperature is 70 ℃ or 90 ℃, can not bear higher ambient temperature; Polyvinyl chloride insulation is heated and can shrinks simultaneously, and thermal circulation performance is poor, influences the fail safe of circuit working; When the common plastics insulated cable was laid in the place of greasy dirt, steam, because the existence of oil and chemical substance, its insulating barrier can swelling, so that aging, be full of cracks, lost mechanical and physical performance and cause scrapping of electric wire; Common plastics insulated cable insulating barrier mechanical strength is relatively low, easily by gouge, damage and cause the energising accident; When the common plastics insulated cable had moisture to immerse, the insulating dielectric layer loss increased, and insulation resistance descends, and influenced electric wire useful life; Common plastics insulated cable anti-flammability is relatively poor, add fire retardant after, electrical insulating property reduces, and produces a large amount of poisonous and harmful smog during burning, and environment, equipment and personnel's life is all had very big harm.
The utility model content
In order to overcome the deficiency of existing cable at aspects such as anti-height (low) temperature, anti-flammability, acid and alkali resistance anti-corrosive properties and electric insulating qualities, the utility model provides a kind of fluoroplastic insulation heatproof anti-corrosion cable, advantages such as this fluoroplastic insulation heatproof anti-corrosion cable has oil resistant, waterproof, radiation proof, ageing-resistant, wear-resisting, acid and alkali resistance, and is nonflammable.
The technical scheme that its technical problem that solves the utility model adopts is: fluoroplastic insulation heatproof anti-corrosion cable comprises at least two conductors, conductor is coated with the perfluoroethylene-propylene insulating barrier, be filled with asbestos cord between the perfluoroethylene-propylene insulating barrier, perfluoroethylene-propylene insulating barrier and asbestos cord are wrapped by the alkali-free glass fibre band, the alkali-free glass fibre band coats screen outward, and screen is wrapped with the perfluoroethylene-propylene sheath.
Beneficial effect of the present utility model is, the long-term permission operating temperature range of perfluoroethylene-propylene insulation control cable is-more than the 100--200 ℃, not only can be in hot environment operate as normal, and can improve the ampacity of cable greatly; And adverse circumstances that can be low temperature resistant; The fluoroplastic insulation cable is owing to fluoroplastics energy acid and alkali resistance and various chemicals, thereby product has fabulous antiseptic property; Fluoroplastic insulation control cable intensity height, hardness are big, can prevent the damage of mechanical external force; When cable had moisture content to immerse, the fluoroplastic insulation control cable was because fluororesin molecule adhesion is big, and in macromolecule key, the C-F key is one of the most firm key.Insulation layer structure is closely knit, can effectively prevent the immersion of external water juice, greasy dirt and moisture; Fluoroplastic insulation cable oxygen index fires hardly up to more than 95%, and its fire resistance is that other material is incomparable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. conductors among the figure, 2. perfluoroethylene-propylene insulating barrier, 3. asbestos cord, 4. alkali-free glass fibre band, 5. screen, 6. perfluoroethylene-propylene sheath.
Embodiment
In Fig. 1, fluoroplastic insulation high-temperature resistant anti-corrosive cable comprises three conductors 1, conductor 1 is coated with perfluoroethylene-propylene insulating barrier 2, be filled with asbestos cord 3 between the perfluoroethylene-propylene insulating barrier 2, perfluoroethylene-propylene insulating barrier 2 and asbestos cord 3 are wrapped by alkali-free glass fibre band 4, the alkali-free glass fibre band 4 outer screens 5 that coat, screen 5 is wrapped with perfluoroethylene-propylene sheath 6.
Claims (1)
