Abstract

A chemical medicine resistant cable is characterized in that a wire core is formed by wrapping an insulating layer made of a low smoke halogen free flame retardation polyolefin material on the outside of a tinned copper wire conductor, a plurality of wire cores and alkali-free glass fibers are stranded into a cable core, and an inner sheath composed of an ethylene-propylene rubber material, a composite aluminum-plastics tape and an outer sheath composed of a low smoke halogen free flame retardation crosslinking hard polyethylene are arranged on the outside of the cable core orderly. Each layer structure of the cable possesses anti-corrosion and aging resistant characteristics, so that the chemical medicine resistant cable of the utility model is very suitable for being used in the chemical industry field.

Description

The chemical-resistant resistance cable

Technical field

The utility model relates to the power cable technical field, relates in particular to a kind of power cable of chemical resistance corrosion.

Background technology

At present, the range of application of cable is more and more wider, use the situation of cable more and more at chemical field, cable often touches various chemicals when using in chemical environment, 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 the more serious situation, can cause the destroyed and short circuit of cable insulation to make the accident of sending out, existing cable normal operation outer protective polyethylene cover, the 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 cover more than 60 ℃ the time also can be corroded, to such an extent as to anti-aromatic cable haves no alternative but adopt metallic sheath, the metallic sheath that has used is mainly plumbous cover and wrinkle metallic sheath, but metallic sheath price, Heavy Weight is general only in very important occasion use.

Summary of the invention

Can to be corroded when existing cable uses in chemical environment in order overcoming, particularly to be difficult to solve aromatic series series solvent to the deficiency of cable corrosion; The utility model provides a kind of chemical-resistant resistance cable, and this chemical-resistant resistance cable can adapt to chemical environment better.

The technical scheme that its technical problem that solves the utility model adopts is: the core of chemical-resistant resistance 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, the sheath that cable core forms for the ethylene-propylene rubber material outward, sheath is outward aluminium-plastic tape, and aluminium-plastic tape is outward the oversheath that the crosslinked hard polyethylene of low-smoke non-halogen flame-retardant forms.

Beneficial effect of the present utility model is, conductor is zinc-plated to have 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 the inner sheath that ethylene-propylene rubber forms has the excellent high fillibility of electrical insulating property, low-density, ageing-resistant, corrosion-resistant and water resistance; 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, and special ability aromatic solvent is to the corrosion of cable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model.

1. tinned copper wire conductors among the figure, 2. insulating barrier, 3. alkali-free glass wool, 4. inner sheath, 5. aluminium-plastic tape, 6. oversheath.

Embodiment

In Fig. 1, the core of chemical-resistant resistance 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, the sheath 4 that cable core forms for the ethylene-propylene rubber material outward, being aluminium-plastic tape 5 outside the sheath 4, is the oversheath 6 that the crosslinked hard polyethylene of low-smoke non-halogen flame-retardant forms outside the aluminium-plastic tape 5.

Claims (1)

1. chemical-resistant resistance cable, it is characterized in that: its core 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, the sheath that cable core forms for the ethylene-propylene rubber material outward, sheath is outward aluminium-plastic tape, and aluminium-plastic tape is outward the oversheath that the crosslinked hard polyethylene of low-smoke non-halogen flame-retardant forms.
