Description
Technical field
The utility model belongs to insulated electric conductor technical field, refers in particular to a kind of double hyer insulation cross-linking radiation high life core level electric wire.
Background technology
At present, the insulated electric conductor that house ornamentation is used has two kinds, and a kind of is BLV, and a kind of is low-smoke halogen-free polyolefin insulated electric conductor.Because polychloroethylene insulation material is relatively inexpensive, production technology is simple, and equipment investment is little, and workshop enterprise just can produce, so BLV floods market in a large number, market ratio is up to 95% left and right.Low-smoke halogen-free polyolefin insulated electric conductor fire resistance is better, environment-protecting asepsis, but insulation resistance is poor, general 5% left and right of market accounting.Once there is fire, BLV burning discharges toxic gas, easily causes personnel's death by suffocation.And relatively environmental protection of low smoke no-halogen wire, but the shortcoming easy adsorbed water molecule that is insulating barrier, under the environment that is having moisture or moisture to exist, insulation resistance declines, and insulation variation easily causes electric leakage accident.
Summary of the invention
The purpose of this utility model is to provide a kind of double hyer insulation cross-linking radiation high life core level electric wire.
The purpose of this utility model is achieved in that
Double hyer insulation cross-linking radiation high life core level electric wire, is coated with one deck inner insulating layer at conductor, at inner insulating layer, is coated with one deck external insulation layer.
Above-mentioned conductor is made with oxygenless copper material.
Above-mentioned interior insulating material is IXPE insulating material.
Above-mentioned outer insulating material is low-smoke halogen-free flame-retardant isolating material.
The utility model compared to existing technology outstanding and useful technique effect is:
1, internal layer of the present utility model is skim IXPE insulating material, and skin is low-smoke halogen-free flame-retardant isolating material, and product has good insulation property, has again good fire resistance.If only have one deck IXPE Insulation Material insulation property better, but fire resistance is poor, when fire occurs, be easy to burning.If only have one deck low-smoke halogen-free flame-retardant isolating material to there is good fire resistance, but insulation property are poor, have under water or moisture existence, easily electric leakage causes security incident.This structure combines two kinds of insulating material that electric wire is conventional preferably, has reached good resultant effect.
2, the utility model is under same gross thickness prerequisite, and double hyer insulation greatly reduces the defect point in manufacturing process than individual layer insulation, occurs that the probability of defect point has reduced by one times, has reduced defect point (spark point), has improved the quality of electric wire.
3, the good mechanical property of the utility model wire structure, insulation, not easy to crack, easy construction.
4, the utlity model has good insulating material formula and product structure, this electric wire can be used in the nuclear island of generation Ⅲ nuclear power to be used, under nuclear island operating mode, can use safely 60 years, in civilian occasion (as family expenses), can reach the useful life of 100 years.
5, the utility model is compared with common polyvinyl chloride cable, and low smoke and zero halogen is nontoxic, have the combination properties such as excellent radioresistance, fire-retardant, heat-proof aging, good electric property, low smoke, zero halogen low toxicity, environment friendly and pollution-free.
6, external insulation layer of the present utility model is after cross-linking radiation, and smooth surface rounding, feel are mellow and full, have higher cost performance.
7, wire structure of the present utility model has water resistance, can in water, use.And the easy moisture absorption gas of common low smoke no-halogen wire insulating barrier causes failure of insulation.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1:
Double hyer insulation cross-linking radiation high life core level electric wire, is coated with one deck inner insulating layer 2 at conductor 1, at inner insulating layer 2, is coated with one deck external insulation layer 3.
Above-mentioned conductor 1 use oxygenless copper material is made, and is the single wire to a use.
Above-mentioned interior insulation 2 materials are IXPE insulating material.
Above-mentioned external insulation 3 materials are low-smoke halogen-free flame-retardant isolating material.
Insulating material-IXPE insulating material in nuclear power field is applied on civil electric wire, has thoroughly solved the inherent shortcoming of BLV and low-smoke halogen-free polyolefin insulated electric conductor.This insulating material has the combination properties such as excellent radioresistance, fire-retardant, heat-proof aging, good electric property, low smoke, zero halogen low toxicity, environment friendly and pollution-free.
The utility model adopts double-layer insulating structure, external insulation is used nuclear island cable special isolation material, compare with common low smoke and zero halogen material there is radiation hardness, cracking resistance, do not discharge hydracid, from fire from putting out, burning is non-toxic and corrosive gas discharges, mechanical performance is good, the features such as long service life, have improved the safety and reliability of electric wire greatly.
The utility model, by thermal life ageing test, could meet the requirement in useful life in lower 60 year of three generations's nuclear power AP1000 adverse circumstances completely, in fixed installation and family expenses occasion, can reach 100 years useful life!
The utility model is after cross-linking radiation, and smooth surface rounding, feel are mellow and full, have higher cost performance.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection range of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection range of the present utility model.
