Abstract
Provided is an acid-proof alkali-proof cable. An aluminum plastic composite belt is arranged outside a cable core. An inner epoxy resin sheath layer is arranged outside the aluminum plastic composite belt. A low-smoke halogen-free flame-retardant crosslinking hard polyethylene layer is arranged outside the inner epoxy resin sheath layer. An outer epoxy resin sheath layer is arranged outside the low-smoke halogen-free flame-retardant crosslinking hard polyethylene layer. The structure of each layer of the cable is provided with anticorrosion aging-resistant characteristics, so that the cable provided by the utility model can be used even in the strong acid and strong alkali environment.
Description
Technical field
The utility model relates to power cable technical field, relates in particular to a kind of power cable that can the anti-caustic corrosion of acid-proof.
Background technology
At present, the range of application of cable is more and more wider, at chemical field, use the situation of cable more and more, when being used in chemical environment, cable often touches various chemicals, oil, solvent, existing general cable generally can produce swelling in chemical environment, sclerosis, be full of cracks, the aging phenomena such as dissolving, shortened the useful life of cable, in more serious situation, can cause the destroyed and short circuit of cable insulation to make the accident of sending out, existing cable is generally used outer protective polyethylene cover, outer protective polyethylene cover has good corrosion resistance to general chemicals, but for benzene, toluene, the general aromatic series such as dimethylbenzene series solvent outer protective polyethylene when more than 60 ℃ overlaps and also can be corroded, to such an extent as to resistance to aromatic cable haves no alternative but adopt metallic sheath, the metallic sheath having used is mainly plumbous cover and wrinkle metallic sheath, but metallic sheath price, Heavy Weight, general only in very important occasion use.
Summary of the invention
While using in chemical environment in order to overcome existing cable, can, by acid and alkali corrosion, particularly be difficult to solve the deficiency of aromatic series series solvent to cable corrosion; The utility model provides a kind of acid-proof alkali prevention cable, and this acid-proof alkali prevention cable can adapt to chemical environment better.
The utility model solves the technical scheme that its technical problem adopts: the core of acid-proof alkali prevention cable is comprised of the insulating barrier of tinned copper wire conductor outer wrapping low-smoke halide-free fireproof composite polyolefine material, many cores and alkali-free glass wool are twisted into cable core, cable core is outward aluminium-plastic tape, aluminium-plastic tape is outward epoxy resin sheath, epoxy resin sheath is the crosslinked hard polyethylene layer of low-smoke non-halogen flame-retardant outward, and the crosslinked hard polyethylene layer of low-smoke non-halogen flame-retardant is outward epoxy resin outer jacket.
Beneficial effect of the present utility model is, conductor is zinc-plated has anti-oxidation corrosion-resisting function; The insulating barrier of low smoke halogen-free flame-retardant polyolefin has that anti-chemical burn into is fire-retardant, the characteristic of low smoke and zero halogen; Alkali-free glass wool plays fire-retardant and etch-proof effect, and aluminium-plastic tape plays electromagnetic shielding and corrosion-resisting function; The oversheath that the crosslinked hard polyethylene of low-smoke non-halogen flame-retardant forms can tolerate the corrosion of various chemical agents, the corrosion of special ability aromatic solvent to cable; Epoxy resin sheath and epoxy resin outer jacket have acid and alkali resistance, salt, oils dielectric corrosion, and special strong basicity resisting can be good, and epoxy resin outer jacket is wear-resisting, withstand voltage, shock-resistant.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. tinned copper wire conductors in figure, 2. insulating barrier, 3. alkali-free glass wool, 4. aluminium-plastic tape, 5. epoxy resin sheath, 6. crosslinked hard polyethylene layer, 7. epoxy resin outer jacket of low-smoke non-halogen flame-retardant.
Embodiment
In Fig. 1, the core of acid-proof alkali prevention cable is comprised of the insulating barrier 2 of tinned copper wire conductor 1 outer wrapping low-smoke halide-free fireproof composite polyolefine material, many cores and alkali-free glass wool 3 are twisted into cable core, cable core is outward aluminium-plastic tape 4, aluminium-plastic tape 4 is outer is epoxy resin sheath 5, epoxy resin sheath 5 is outer is the crosslinked hard polyethylene layer 6 of low-smoke non-halogen flame-retardant, and the crosslinked hard polyethylene layer 6 of low-smoke non-halogen flame-retardant is outer is epoxy resin outer jacket 7.
Claims (1)
1. an acid-proof alkali prevention cable, its insulating barrier by tinned copper wire conductor outer wrapping low-smoke halide-free fireproof composite polyolefine material forms, many cores and alkali-free glass wool are twisted into cable core, it is characterized in that: cable core is outward aluminium-plastic tape, aluminium-plastic tape is outward epoxy resin sheath, epoxy resin sheath is the crosslinked hard polyethylene layer of low-smoke non-halogen flame-retardant outward, and the crosslinked hard polyethylene layer of low-smoke non-halogen flame-retardant is outward epoxy resin outer jacket.
