Abstract
The utility model relates to a nuclear island cable for a nuclear power station, and a conductor adopts a multiple tinning copper conductor strand structure. On the conductor, a squeeze bag is composed of an insulating layer composed of radiation-resistant ethylene propylene rubber insulating material, and the insulating layer carries out steam crosslinking. An insulating line core is stranded into the cable, a gap of a cable core is packed with a packed layer composed of a dust free rock cotton rope, and then, the packed layer is wound with a bag band. On the bag band, the squeeze bag is provided with a high flame resistant oxygen separation layer and a radiation-resistant thermosetting rubber protective layer. The utility model provides a 1E stage K1 class nuclear island cable for the nuclear power station, and the nuclear island cable has low smoke, no halogen, flame resistance, radiation resistance, LOCA (a coolant loss accident) resistance and high insulating property. The product reduces the construction cost of the nuclear power station.
Description
Affiliated technical field
The utility model relates to a kind of cable, especially a kind of used in nuclear power station 1E level K1 class nuclear island cable.
Background technology
2003, nuclear power developing was included into State Grid's development plan first, sign China nuclear power industry enters into stage of accelerated development by original optimum development, is to reduce the nuclear power cost, and country has determined the development aim of autonomy-oriented, production domesticization.Because the special environment for use of nuclear power station requires very high to operational outfit.The used in nuclear power station nuclear island cable is generally electric at common cable, on the basis of mechanical property, also must possess low cigarette, Halogen, fire-retardant, radiation hardness, anti-LOCA (coolant loss accident) performance.In each big nuclear power station of having gone into operation at present and having built, only the outer used in nuclear power station 1E level K3 class cable of containment has begun progressively to domesticize, and the domestic still untapped production of used in nuclear power station 1E level K1 class nuclear island cable, dependence on import always, Buying Cycle is very long, the working service difficulty, the equipment cost costliness.
Summary of the invention
The purpose of this utility model provides a kind of used in nuclear power station 1E level K1 class nuclear island cable that possesses excellent low cigarette, Halogen, fire-retardant, radiation hardness, anti-LOCA (coolant loss accident) and high insulating property, and this product will reduce construction of nuclear power station cost significantly.
The technical solution of the utility model is: conductor adopts many tin-coated copper conductor lay configuration, extrudes the insulating barrier that is constituted and carried out vapor crosslinking by the ethylene-propylene rubber of anti-irradiation insulating material on conductor, and insulating barrier adopts bilayer to extrude.The stranded stranding of insulated wire cores is filled the packed layer that is made of dustless mineral wool rope in the cable core gap during stranding, and wrapped again band extrudes the solid type rubber outer jacket of high flame retardant oxygen barrier layer and radiotolerant on band.
Described insulating barrier, packed layer, band, oxygen barrier layer, outer jacket all adopt the material with low cigarette, Halogen, fire resistance.
Owing to adopted technique scheme, cable to possess excellent low cigarette, Halogen, fire-retardant, radiation hardness, anti-LOCA (coolant loss accident) and high insulating property.Insulating material makes cable allow the working temperature grade of use to improve greatly after crosslinked, and therefore current-carrying capacity of cable increases, and cable operate power, useful life improve, and belong to the new generation of environment protection product.After adopting this technical scheme, this product has reached external like product level, will reduce construction of nuclear power station cost significantly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a sectional view of the present utility model.
Among the figure: 1, conductor, 2, insulating barrier, 3, packed layer, 4, band, 5, oxygen barrier layer, 6, outer jacket.
Embodiment
Among the embodiment as shown in the figure, conductor (1) adopts many tin-coated copper conductor lay configuration, and on conductor extruded insulation layer (2), insulating barrier (2) adopts the ethylene-propylene rubber of anti-irradiation insulating material bilayer to extrude, insulating barrier (2) closely is extruded on the conductor (1), and carries out vapor crosslinking.During the stranded stranding of insulating barrier (2) core betwixt the crack with dustless mineral wool rope as packed layer (3).Wrapped band (4) on packed layer.On band, extrude oxygen barrier layer (5), extrude outer jacket (6) with the solid type rubber material of radiotolerant at last with packing material.Described insulating barrier, packed layer, band, oxygen barrier layer and outer jacket all select for use low cigarette, Halogen, fire proofing to make.
Claims (1)
1. used in nuclear power station nuclear island cable, it is characterized in that: conductor adopts many tin-coated copper conductor lay configuration, on conductor, extrude the insulating barrier that constitutes and carry out vapor crosslinking by the ethylene-propylene rubber of anti-irradiation insulating material, the stranded stranding of insulated wire cores, and fill the packed layer that constitutes by dustless mineral wool rope in the cable core gap, wrapped again band extrudes the solid type rubber outer jacket of high flame retardant oxygen barrier layer and radiotolerant on band.
