Abstract
The present invention discloses a novel environmental protection safety type fireproof cable. The novel environmental protection safety type fireproof cable comprises a cable inner core and a cable outer layer, the cable inner core is formed by twisting three or four conductive wire cores, and each conductive wire core is formed by extruding an insulating shielding layer, an XLPE insulating layer, a conductor shielding layer and a fireproof layer on a conductor orderly from outside to inside. The cable outer layer is formed by extruding a semi-conductive water-blocking tape, a lining layer, a copper wire copper strip combined shielding layer, a semi-conductive buffer water-blocking tape, an plastic-aluminum composite belt and a ceramic halogen-free flame retardant fireproof sheath on the cable inner core orderly from inside to outside. The novel environmental protection safety type fireproof cable of the present invention is fireproof, waterproof, nontoxic and environment friendly, is high in safety, is suitable for keeping the electrification even on a specific disaster condition, and is a low-smoke halogen-free non-toxic nuisanceless green safe cable used by a disaster rescue power supply and an emergency power supply, such as fire extinguishing, alarm, illumination, communication, etc.
Description
Technical field
The present invention relates to cable, particularly relate to a kind of novel environmental protection and safety type fireproof cable.
Background technology
At present, the occasion that the fire safety condition such as domestic skyscraper, oil, mine, metallurgy, boats and ships, power station, subway, tunnel is high, the cable insulation used, restrictive coating mostly adopts the insulating material of Halogen.Fire, once spread, not only can produce a large amount of dense smoke, and can produce the very strong hydrogen halide of the corrosivity with " secondary disaster ", jeopardizes the life of people, harm equipment and contaminated environment.Even adopt the flame-retardant insulating material of Halogen, low halogen; also can only delay flame-retardant insulating material and be burnt till the time of powder; if continue to be burnt; just gradually powder and come off; lose protective effect; electric wire is easy to breakdown and causes short circuit, thus is difficult to ensure communication, electric power in case of fire safe and smooth.Along with the high speed development of World Economics and World Environment Organization are to the requirement of environmental protection, anxious environmental type safety cable to be developed is to meet the needs of human kind sustainable development, and this is the development trend of countries in the world, is also the common heartfelt wishes of the global people.
Summary of the invention
In order to meet above-mentioned requirements, the object of the invention is to provide a kind of novel environmental protection and safety type fireproof cable.
The solution of the present invention is as follows: a kind of novel Environmental Safety fireproof cable, comprises cable inner core and cable outer layer, and cable inner core is by three or four conductor wire cores are stranded forms; Described conductor wire core is extruded in from outside to inside on conductor successively by insulation screen, XLPE insulating barrier, conductor shield and flame retardant coating to form; Cable outer layer is extruded in from inside to outside successively on cable inner core is formed by semiconductor waterstop, inner covering, the combination of copper wire copper strips screen, semi-conductive buffer water-blocking band, aluminium-plastic tape and ceramic halogen-free flameproof fireproof.
Described conductor is well-regulated by the soft round copper wire that some diameters are identical, and by concentric type, and successive layers time is according to different directions strand system.
Described flame retardant coating adopts high-quality synthetic mica carrying material.
Described copper wire copper strips combination screen forms on one deck copper strips by one deck copper wire is wrapped.
Beneficial effect of the present invention: the present invention has fire prevention, waterproof, nontoxic, environmental protection, fail safe are high, the cable of energising still can be maintained under being suitable for specific disaster scenario, disaster relief power supply and fire extinguishing, report to the police, illumination, the low smoke and zero halogen that uses of emergency power supply of communication etc., non-toxic and non-pollution green safety cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Wherein: 1, conductor; 2, flame retardant coating; 3, conductor shield; 4, XLPE insulating barrier; 5, insulation screen; 6, semiconductor waterstop; 7, inner covering; 8, copper wire copper strip shielding layer; 9, semi-conductive buffer water-blocking band; 10, aluminium-plastic tape; 11, ceramic halogen-free flameproof fireproof.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of novel Environmental Safety fireproof cable, comprises cable inner core and cable outer layer, and cable inner core is by three or four conductor wire cores are stranded forms; Described conductor wire core is extruded in from outside to inside successively on conductor 1 by insulation screen 5, XLPE insulating barrier 4, conductor shield 3 and flame retardant coating 2 to form; Cable outer layer is extruded in from inside to outside successively on cable inner core is formed by semiconductor waterstop 6, inner covering 7, the combination of copper wire copper strips screen 8, semi-conductive buffer water-blocking band 9, aluminium-plastic tape 10 and ceramic halogen-free flameproof fireproof 11, aluminium-plastic tape 10 not only serves the effect of electromagnetic shielding but also serves radial moistureproof effect, have employed semiconductor waterstop 6 and semi-conductive buffer water-blocking band 9, can effectively prevent the longitudinal direction of moisture, moisture from invading, ceramic halogen-free flameproof fireproof 11 really reaches the object of fire-fighting, fire prevention and safety and environmental protection.
Described conductor 1 is well-regulated by the soft round copper wire that some diameters are identical, and by concentric type, and successive layers time is according to different directions strand system.
Described flame retardant coating 2 adopts high-quality synthetic mica carrying material.
Described copper wire copper strips combination screen 8 forms on one deck copper strips by one deck copper wire is wrapped.
The sectional area of conductor wire core is 4 ~ 500mm
2, geometry is round.Under the high temperature of this cable more than 500 DEG C and flame ablation, organic principle ablatedly in a short period of time can change into hard ceramic-like material, form the isolation layer that one deck is good, stop burning away of flame, and the ablation time is longer, temperature is higher, hard effect is more obvious, the fire-resistant environment of 1200 ~ 1500 DEG C can be reached, remained without any ashes by after burning simultaneously, really serve the object of good fire-fighting, fireproofing function and safety and environmental protection.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection scope of the present invention.
