Abstract
The utility model discloses a cable which is characterized in that of environment protection and chemical corrosion resistant. The cable comprises a conductor which is wrapped by insulating layer, a screening layer, and an outer protection jacket. Within the inner wall of the screening layer, a layer of glass fiber without alkali is arranged, and the mental wires that work as conduction current are also arranged within the layer of glass fiber without alkali. The utility model solves the problem of that when cables used for electric control and electricity transmission in oil plant, petrochemical works, and generally chemical plant often get contact with aromatic series solvent, the cable has a poor resistance to chemical medicine, oil series, solvent erosion attack, and has a lower capability of preventing magnetic field, and resisting antistatic disturbance.
Description
Technical field
The utility model relates to a kind of environment-friendly type shielding and resistance to chemical attack cable.
Background technology
Cable in oil plant, petrochemical plant and the vague generalization factory is laid in; touch various chemicals, oil, solvent through regular meeting; thereby when cable cover(ing) is general organic material; will produce aging phenomena such as swelling, sclerosis, be full of cracks, dissolving, sometimes in addition cause the insulation ruined accident.In order to prevent the chemical aging of cable, though can use Polyethylene insulated cable, the outstanding polyethylene of chemical resistance also will produce expansion for aromatic series such as benzene,toluene,xylene series solvent in time more than 60 ℃, even dissolving soon.,, have to for this reason, as use plumbous cover, wrinkle metallic sheath etc. based on metal sheathed cable as the cable that anti-aromatic series is used.But, this metal sheathed cable, price general charged is expensive, Heavy Weight, operating expenses height, is only limited at present on important circuit and uses.Reduce the useful life of cable, motor, even accidents such as puncture can appear in cable insulation, can't adapt to the requirement of frequency conversion occasion.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and overcome that above-mentioned deficiency, shield effectiveness are good, the environment-friendly cable of anti-chemical aging.
The utility model is achieved in that
Environment-friendly type shielding and resistance to chemical attack cable comprise the conductor, screen, the oversheath that are coated with insulating barrier, and the inwall of described screen is provided with the alkali-free glass ribbon layer, is provided with the metal drainage thread in the described alkali-free glass ribbon layer.
Described screen is plastic-aluminum combined embossing band.
Described metal drainage thread is a tinned copper wire.
Described insulating barrier is a low smoke halogen-free flame-retardant polyolefin.
Described oversheath is the crosslinked hard polyethylene of low-smoke non-halogen flame-retardant.
The beneficial effects of the utility model:
1.. make drainage thread owing to be furnished with special-purpose copper wire in the cable shield, formed the full-shield structure, drainage thread not only helps cable grounding to be handled, and can guarantee the continuity of screen.
2.. because the vertical bag of two-sided plastic-coated aluminium strip embossing technique for sticking is adopted in the shielding of cable, has shielding preferably, anti-electromagnetic interference performance, can effectively suppress of the infiltration of all kinds of chemicals and so on material to cable inside, its resistance to chemical reagents and inhibition medicine permeability, be only second to totally-enclosed metallic sheath, and have combination properties such as good fire-retardant, waterproof, fire-retardant, fire prevention, resistance to compression and bending, can guarantee that the cable operation reliably and with long-term and lay the maximum adaptation of environment.
3.. because insulation, the oversheath of cable all adopt the low-smoke non-halogen flame-retardant environment-friendly materials; cable make process, transport, lay and use in; no poisonous and harmful substance produces; human body there is not any health effect; surrounding environment is not had any pollution, protected natural resources and biological environment greatly.
4.. because the oversheath of cable adopts high-quality low-smoke non-halogen flame-retardant crosslinked (hard) polyethylene material, can tolerate all kinds of chemicals, oil, solvent, particularly aromatic solvent, improve the useful life of cable the dissolving that cable cover(ing) causes.
5.. the outside diameter of cable is little, in light weight, good bending property, and operating expenses is low, excellent, the anti-aromatic solvent corrosive nature of shielding properties height, price economy.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model cross section structure schematic diagram
Among the figure: 1. conductor 2. insulating barriers 3. drainage threads 4. bands 5. screens 6. oversheaths
Embodiment
With reference to the accompanying drawings, environment-friendly type shielding and resistance to chemical attack cable are made up of conductor 1, insulating barrier 2, drainage thread 3, band 4, screen 5, oversheath 6.Conductor meets the regulation of GB3953, adopt high conduction electrician circular copper wire, insulation is adopted the high-quality low smoke halogen-free flame-retardant polyolefin to extrude and is formed, drainage thread adopts tinned copper wire, band adopts the alkali-free glass silk ribbon, the vertical bag of aluminium-plastic tape embossing technique for sticking is adopted in shielding, and oversheath adopts high-quality low-smoke non-halogen flame-retardant crosslinked (hard) polyethylene to extrude and forms.
This product is widely used in oil plant, petrochemical plant and the vague generalization factory touching in the electrical control, electric power transfer of aromatic solvent through regular meeting; cable has chemical-resistant resistance, oils, solvent corrosion ability preferably, also has anti-magnetic field, antistatic ability simultaneously.Cable can be used for direct-burried and cable installation in pipe.
