Abstract
The invention relates to a halogen-free flame-resistant anti-cracking IE-grade cable for a nuclear power plant. The halogen-free flame-resistant anti-cracking IE-grade cable comprises a plurality of conductors, a shielding layer, a lapping layer and an outer protective layer. An inner insulating layer and an outer insulating layer are extruded on the outside of each conductor, an insulating wire core is formed by means of lapping a polyester belt on each outer insulating layer and longitudinally wrapping an aluminum-plastic composite belt on the outer insulating layer, alkali-free glass fiber ropes are filled among the multiple insulating wire cores, a high-flame-resistance lapping belt is lapped on the multiple insulating wire cores filled with the alkali-free glass fiber ropes to form a cable core, and the copper wire braided shielding layer, the halogen-free lapping layer and the irradiation cross-linked halogen-free low-smoke flame-resistant polyolefin outer protective layer are sequentially arranged on the cable core from inside to outside. The halogen-free flame-resistant anti-cracking IE-grade cable is reasonable in structure, is made from novel materials, and is of a double-layer insulating composite structure, novel insulating materials added with special media are adopted, and accordingly electric performance, flame-resistant performance and mechanical properties are organically unified.
Description
Technical field
The present invention relates to a kind of cable for nuclear power station, relate in particular to a kind of used in nuclear power station halogen-free flameproof cracking resistance IE level cable.
Background technology
A kind of used in nuclear power station halogen-free flameproof cracking resistance IE level cable not only will have the general characteristic of common cable, and should have cracking resistance, low cigarette, Halogen, the performance that fire-retardant, the life-span is long, also to have specifically environment resistant, such as radiation hardness, anti-LOCA.At present, it is day by day frequent that extraordinary serious natural calamities occurs, and should cause that by the nuclear safety of its initiation people introspect, and the cable that such cable, particularly nuclear facility use should have higher fail safe and more excellent economy.
Summary of the invention
The present invention provides in order to overcome the above problems that a kind of good insulation preformance, fire resistance are good, the used in nuclear power station halogen-free flameproof cracking resistance IE level cable of good mechanical property.
Technical scheme of the present invention is: comprise many conductors, screen, lapping layer and outer jacket, conductor extrudes inner insulating layer and external insulation layer outward, wrapped polyester belt, vertical alclad plastic composite strip become insulated wire cores on the external insulation layer, many eradication edge cores fill the alkali-free glass wool rope and wrapped high flame retardant twining package tape becomes cable core, set gradually from the inside to the outside proof copper-wire braided screen, Halogen band lapping layer and irradiation crosslinking halogen-free low-smoke flame-proof polyolefin outer jacket on the described cable core.
Described conductor is copper free wire.
The present invention is rational in infrastructure, and material is novel, adopts the new insulation material of double hyer insulation composite construction and adding special media, has realized preferably the organic unity of electrical property, fire resistance and mechanical performance.
