Description
Technical field
The present invention relates to technical field of electric wires and cables, the low cigarette environmental protection equipment particularly power engineering used.
Background technology
In recent years along with its people are to quality, environmental protection, low-carbon (LC), the understanding degree of safety is more and more higher, going from bad to worse particularly along with Global Environmental Problems, the research of people to environmental problem is forced more and more to be paid attention to, government department is also to the regulation prohibitting the use environment-friendly cable in big-and-middle-sized building or public place simultaneously, and China's engineering project and home cabling industry appoint so a large amount of common PVC material that adopts at present, competition is also like a raging fire, this makes domestic many producers adopt jerry gimmick to reduce costs, this makes the cable produced there is very large potential safety hazard, the security of the lives and property of consumer can be affected undoubtedly.Respectively strict environmental protection standard is formulated to cable products in states such as European Union, the U.S., Japan, and forbidden the application of PVC material by legislation, progressively limited the production of PVC cable.According to statistics, the fire of 35% causes because of the aging short circuit of electric wire in the world, and in fire, the personnel death of 1/3rd is because the poison gas of PVC cable burning release causes.For above-mentioned problem, existing sparetime university many employings low smoke and zero halogen material substitution, but shown by the investigation of laying actual installation, using, low smoke and zero halogen material water absorption is strong, wear no resistance (be mainly manifested in poling process, insulating barrier easily damaged), thus cause lay a period of time after or just laid, just there is insulation resistance lower than resistance lower than safety value, poor stability.
Now traditional power cable, mostly adopt circular single line stranded conductor, the activity coefficient of stranded conductor is 0.75, after pressing, activity coefficient reaches 0.82-0.92, therefore the conductor diameter caused is bigger than normal, add insulation, fill, the consumption of armouring and sheath material, thus increase production cost and the object not reaching environmental protection, and common armoured cable sheath adopts PVC material, containing halogen in material, toxic gas is produced during burning, this gas amount of being fuming is large, light transmittance is low, not only cause environmental pollution, but also the rescue work of restriction scene of fire.
Present cable use is more and more wider, such cable will be applied in each complex environment, just require that cable will have various resistance properties, but fireproofing of cable performance is too poor now, the material of cable jacket directly affects the anti-corrosion property of cable, the complexity of cable laying, and affecting the useful life of cable, the use for user brings various inconvenience; And the environmental consciousness of people is more and more heavier, then require cable also environmental protection, safety.The packed layer that the insulating barrier that existing environment-friendly cable comprises conductor, polyvinyl chloride is made, polyvinyl chloride are made and the protective layer that polyvinyl chloride is made; Insulating barrier parcel conductor, packed layer wrap insulate layer, protective layer parcel packed layer; existing environment-friendly cable is that polyvinyl chloride is made, and containing a large amount of halogen, environment-friendly cable burning can produce a large amount of hydrogen chloride; hydrogen chloride is poisonous, can make that personnel health comes to harm, life is on the hazard.
