Abstract
The utility model discloses a network cable for an AP1000 nuclear power plant and belongs to the technical field of cables. The network cable comprises a cable core and a sheath arranged at the outermost layer of the cable. The network cable is characterized in that a cable core is composed of a cross-shaped framework arranged at the center thereof, and insulated wire cores respectively arranged in the four gaps of the cross-shaped framework. The insulated wire cores are wrapped with polyimide radiation-resistant layers respectively. The outside of the cable core is wrapped with a PET buffer warping tape. The PET buffer warping tape is longitudinally wrapped with a stainless steel metal sheath through argon arc welding. According to the technical scheme of the utility model, the insulating layer of the network cable is wrapped with a polyimide film, so that the insulated radiation-resistant property of the cable is improved. After the cabling process, the cable is longitudinally wrapped with a stainless steel metal sheath through argon arc welding, so that the fire-resistant, radiation-resistant, high-temperature-resistant and other performances of the cable are ensured. The cable is made of non-hygroscopic materials and the sheath is made metal materials. In this way, the stability and the timeliness of the electrical transmission of the cable are ensured. Therefore, the moisture-proof performance of the cable is improved and the electrical transmission performance of the cable is ensured.
Description
Technical field
The utility model relates to a kind of structure of cable, and especially the structure of AP1000 used in nuclear power station network cable belongs to the cable technology field.
Background technology
According to the planning that National Development and Reform Committee formulates, the year two thousand twenty planning nuclear power installation scale reaches 9,000 ten thousand kilowatts, strives reaching 100,000,000 kilowatts, and nuclear power EQUIPMENT MARKET GUIDE scale is expected to reach nearly trillion yuan.Three nuclear power stations of China first employing AP1000 technology put into operation in 2011, estimated operation in 2015.As the operation in China of the AP1000 technology of main force's heap type, will drive the construction of the third generation nuclear power station in the whole world, global nuclear power will reach 3～50,000 km with the market demand of cable every year, and the output value reaches 40～6,000,000,000 yuan, and market prospects are very wide.
According to the requirement of AP1000 nuclear power station to cable, thermal lifetime was brought up to 60 years from 40 years, to the cable security demands for higher performance.And stack top cable and the island inner cable except 1 district need satisfy the simulation LOCA experiment in the AP1000 system, other regional cables all need to satisfy the radiation aging performance, and for the network cable product of transmission signal the challenge of peak demand has been proposed, because of its external diameter minimum in the nuclear power product, electric parameter is maximum.
As everyone knows, the cables of nuclear power product also should satisfy low cigarette, Halogen, performance such as fire-retardant except needs satisfy radiation-resistant property, also need to satisfy the humidity resistance that blocks water in the design that has.Fire-retardant and waterproof and deposit, proposed a difficult problem for designing and developing of cable.Therefore, need provide a kind of AP1000 of being applicable to nuclear power network cable product.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provide a kind of low cigarette, Halogen, fire-retardant, moistureproof, radiotolerant AP1000 used in nuclear power station network cable block water.
The purpose of this utility model is achieved through the following technical solutions: AP1000 used in nuclear power station network cable, comprise cable core and be arranged on the outermost sheath of cable, it is characterized in that described cable core is made of the insulated wire cores that arranges respectively in four gaps of crossing skeleton, crossing skeleton of center setting; Equal wrapped polyimides band radiation protective layer on the described insulated wire cores; Wrapped PET buffering band is indulged bag soldering stainless steel metallic sheath with argon arc welding on the PET buffering band on the described cable core.
Described insulated wire cores constitutes by extruding crosslinked polyetylene insulated layer on copper or the tin-coated copper conductor.
Be provided with non-hygroscopic cavernous body inserts in the described cable core space.
The utility model from the insulation of cable, become cable structure, waterproof, anti-irradiation, low cigarette, Halogen, fire-retardant etc. many-sidedly consider, wrapped one deck polyimide film on insulating barrier has increased the radiation-resistant property of cable insulation; Behind stranding, adopt the vertical bag of stainless steel argon arc welding welding, guaranteed fireproofing of cable, radiation hardness, performance such as high temperature resistant; Cable material is non-absorbent material, and sheath is metallic sheath, can guarantee electrical communications stability, promptness, thereby improves the humidity resistance of cable, guarantees electric transmission performance.The utility model has designed and has been applicable to AP1000 nuclear power network cable product in conjunction with the design experiences of K1, K3 class cable product, and simple and reasonable, moistureproof, anticorrosion, high temperature resistant, flame-retardant have good radiation resistance, excellent mechanical performance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 crossing skeleton, 2 conductors, 3 insulating barriers, 4 polyimides band radiation protective layer, 5 PET buffering band, 6 stainless steel metal sheaths, 7 non-hygroscopic cavernous body inserts.
