Abstract
The utility model relates to a fireproof radiation-resistant cable for a nuclear island of a nuclear power station. The cable successively comprises single or multiple intertwisted insulating cable cores, a non-hygroscopic band, a metal tantalum band and an oversheath from inside to outside, wherein each insulating cable core successively includes a Category-5 copper conductor and a fireproof silicone rubber insulating layer from inside to outside, fillers are arranged between gaps among the cable cores, the oversheath is made of phenylene silicone rubber, and the fillers are made of non-hygroscopic materials. The fireproof radiation-resistant cable for the nuclear island of the nuclear power station is high in insulation, fireproof, flame-retardant and radiation-resistant performance, simple in structure, simplified in technology and low in production cost.
Description
Technical field
The utility model belongs to the power cable technical field, is specifically related to the fire-resistant rdaiation resistant cable for nuclear island of nuclear power station.
Background technology
Near the cable that uses nuclear island of nuclear power station or nuclear island except satisfying on the basis of common cable electric property, mechanical performance, also must possess high electrical performance, high flame retardant and radiation resistance.The used in nuclear power station cable feature is more single at present, usually adopt fire-resistant silicon rubber insulating barrier, high flame retardant packed layer and low smoke and zero halogen oversheath, though have the fireproof high-temperature resistant characteristic, but the shielding action to radiation is very little, can't satisfy above-mentioned performance requirement simultaneously, it is aging that long-term radiation easily causes silicone rubber insulation layer, causes decreasing insulating, changes the cable internal performance simultaneously.Patent CN 201383373Y discloses a kind of radioresistance low pressure power cable for nuclear power plant, its conductor is wrapped with inner insulating layer and external insulation layer, oversheath comprises inner restrictive coating, external sheath layer and the steel band lapping layer between the two, be provided with separator between cable core and the oversheath, though have the radioresistance characteristic, but the construction of cable and complex manufacturing, the cost height.
The utility model content
At the above-mentioned defective that existing used in nuclear power station cable exists, the purpose of this utility model is to provide uses fire-resistant rdaiation resistant cable in a kind of nuclear island of nuclear power station.This cable has high-insulativity, high fire resistance, high flame retardant and high radiation resistance, and is simple in structure, work simplification, and production cost is low.
The technical solution of the utility model is as follows:
Use fire-resistant rdaiation resistant cable in the nuclear island of nuclear power station, it is followed successively by from inside to outside: single or many mutual stranded insulated wire cores, non-hygroscopic band, metal tantalum belt and oversheaths; Described insulated wire cores is followed successively by 5 class copper conductors and fire-resistant silicon rubber insulating barrier from inside to outside; Gap between described insulated wire cores is provided with filler; Jacket material is phenylene silicone rubber.
Its further technical scheme is:
The quantity of described insulated wire cores is 5.
Filler is non-absorbent material.
Compare with existing used in nuclear power station cable, have the following advantages with fire-resistant rdaiation resistant cable in this nuclear island of nuclear power station:
1. the twisted copper conductors surface adopts fire-resistant silicon rubber as insulating barrier; this rubber has " potteryization " characteristic; can form hard housing after thermal-flame burns, the protection cable is without prejudice, thereby has guaranteed the high-insulativity of cable, high fire resistance and high flame retardant simultaneously.
2. be provided with layer of metal tantalum band between non-hygroscopic band and the oversheath, it has very strong radiation resistance, can effectively shield the radiation in the nuclear island, guarantees that the not raying of fire-resistant silicon rubber insulating barrier influences and generation is aging, decreasing insulating guarantees that simultaneously the cable internal performance does not change.
3. the oversheath acid and alkali-resistance rain resistance of phenylene silicone rubber material improves the weatherability of cable greatly.
4. simple in structure, work simplification, production cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
As shown in Figure 1, be followed successively by from inside to outside with fire-resistant rdaiation resistant cable in this nuclear island of nuclear power station: 5 mutual stranded insulated wire cores, non-hygroscopic band 4, metal tantalum belt 5 and oversheaths 6; Described insulated wire cores is followed successively by 5 class copper conductors 1 and fire-resistant silicon rubber insulating barrier 2 from inside to outside; Gap between described insulated wire cores is provided with filler 3; Particularly, oversheath 6 materials are phenylene silicone rubber, and filler 3 is non-absorbent material.
In actual moving process, metal tantalum belt 5 radiation hardness can effectively shield from the radiation in the nuclear island of nuclear power station, guarantee that the 2 not rayings of fire-resistant silicon rubber insulating barrier influence and generation is aging, and decreasing insulating guarantees that simultaneously the cable internal performance does not change; Fire-resistant silicon rubber insulating barrier 2 has " potteryization " characteristic, can form hard housing after thermal-flame burns, and the protection cable is without prejudice, thereby has guaranteed the high-insulativity of cable, high fire resistance and high flame retardant simultaneously; Oversheath 6 materials are selected from phenylene silicone rubber, and the acid and alkali-resistance rain resistance improves the weatherability of cable greatly.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion within protection range of the present utility model, can be done any type of modification referring to claim.
