Abstract
The invention relates to a copper-clad aluminum core irradiation crosslinking low-smoke zero-halogen flame-retardant polyethylene insulated cable, belonging to the field of cable technology. The cable consists of an aluminum core, a copper-clad layer, a wrapping belt I, an insulating layer I, a wrapping belt II and an insulating layer II, wherein the aluminum core is surrounded by the copper-clad layer; the copper-clad layer is surrounded by the wrapping belt I; the wrapping belt I is surrounded by the insulating layer I; the insulating layer I is surrounded by the wrapping belt II; and the wrapping belt II is surrounded by the insulating layer II. The cable has the advantages that the heat resistance of the irradiated crosslinked polyethylene reaches up to 105 DEG C, a physical crosslinking way is adopted by the irradiation crosslinking, no water gets involved in the whole crosslinking process, the water molecule content in insulation is not more than 100PPM, and the insulation purity is high, so that the irradiation crosslinking cable has unique excellent characteristics in the aspects of electrical property and mechanical property, and the service life of the cable reaches more than sixty years. Meanwhile, the cable has the characteristics of being light in weight and simple in structure, being not limited by drop, and the like.
Description
Technical field
The present invention relates to copper-covered aluminum-core irradiated crosslinking low-smoke and halogen-free flame retardant polyethylene insulated cable, belong to the cable technology field.
Background technology
In current industrialization society, the energy and information are two big pillars of society, and no matter are electric energy or transmission of Information, all be unable to do without electric wire, particularly high-rise commerce and trade building, subway, tunnel and nuclear power station etc.For the fire prevention of satisfying above-mentioned place and the laws and regulations requirement of environmental protection, should lay the low-smoke non-halogen flame-retardant fire-resistant wire and cable.As everyone knows; Although common BLV cable has good machinery, electric and processing characteristics; But maximum shortcoming be inflammable, caloric value is high, flame propagation speed; Can discharge a large amount of poisonous and hazardous corrosive gas and dense smoke during burning, cause " secondary disaster ".These gases and dense smoke not only injure life security, but also severe corrosion equipment and building cause very big difficulty for simultaneously fire-extinguishing and lifesaving and the property work of withdrawing.Everything makes people recognize that further cable is except that fire-retardant; Also must possess characteristics such as high temperature resistant, anti-aging, smokeless nontoxic and low corrosion; Therefore, the low cigarette of exploitation, Halogen, nontoxic fire product have become a comprehensive developing direction of current cable industry.
Summary of the invention
In order to satisfy above demand, purpose of the present invention is to provide copper-covered aluminum-core irradiated crosslinking low-smoke and halogen-free flame retardant polyethylene insulated cable, characteristics such as resistivity is little, halogen-free flameproof, good insulating that it has.
The present invention is made up of aluminium core, copper clad, band one, insulating barrier one, band two, insulating barrier two; The aluminium core is surrounded by copper clad, and copper clad is surrounded by band one, and band one is insulated layer one encirclement, and insulating barrier one is surrounded by band two, and band two is insulated layer two encirclement.
Irradiated crosslinking low-smoke and halogen-free flame retardant and fire-resistant wire and cable; It is the external import low-smoke halogen-free material of utilization; The high energy electron line that utilizes electron accelerator to produce carries out cross-linking radiation to cable, makes the insulating barrier of cable become the 3 D stereo network structure by the linear molecule structure, has formed the three-dimensional lattice less than hydrone; At polyethylene surface and the inner compacted zone that forms; Thereby stoped combining of hydroxide and hydrone effectively, this crosslinking method not only improved the heatproof of electric wire, wear-resisting and fire resistance, and main is to have played resistance effect.This crosslinking method does not have high temperature, anhydrous, can make polyethylene crosslinking, can improve the fire-retardant and electric property of cable again.Make cable have low cigarette, Halogen, characteristics such as fire-retardant, fire-resistant and high temperature resistant.Concrete performance is following: temperature resistant grade is high: it is 135 ℃ (common cable is 70 ℃ or 90 ℃) that conductor allows working temperature for a long time; Fire resistance is good: bunched burning test is a category-A.(common cable is the C class); No flue gas poison gas, light transmittance >=90%, pH value >=6.0 (common low-smoke halogen-free cable light transmittance >=60%, pH value >=4.3); Mechanical performance is excellent.Abrasion resistance reaches 160,000 times, and useful life was above 50 years.
The scope of application has irradiated crosslinking low-smoke and halogen-free flame retardant and fire-resistant wire and cable to be applicable to 10kv and fire-retardant, fire-resistant, smokeless, the nontoxic and resistant to elevated temperatures important place of following power electrical power trans mission/distribution system, control circuit and various requirement, can be widely used in nuclear power station, power plant, steel mill, oil well, machine room, school, public place of entertainment, crowded place and high-rise building etc.
Progress along with society; The raising of the reach of science and people's environmental consciousness; To irradiated crosslinking low-smoke and halogen-free flame retardant and fire-resistant wire and cable demand with increasing; Also will progressively go deep into the research of the new material of instead of copper conductor simultaneously, believe that the development of irradiated crosslinking low-smoke and halogen-free flame retardant and fire-resistant wire and cable will have very wide prospect.
Advantage of the present invention: can reach 105 degree through the crosslinked polyethylene heat resistance behind the irradiation; Cross-linking radiation is the physical crosslinking mode, the whole crosslinked intervention that does not have water, and the hydrone content in its insulation is not more than 100PPM; Insulation purity is high; Thereby the cross-linking radiation cable is at electrical property, and mechanical properties has unique good characteristic, and cable life can reach more than 60 years.The while cable has in light weight, simple in structure, lays characteristics such as not receiving the drop restriction.
