Abstract
The utility model relates to a high temperature resistant cracking resistant nuclear power single-core control cable which comprises a cable core conductor which is coated by an insulating layer which is coated by a tinned copper wire braided layer. The tinned copper wire braided layer is coated by an environment-friendly high inflaming retarding oxygen barrier layer which is coated by a radiation resistant layer which is coated by a low smoke halogen-free environment-friendly radiation resistant cross-linked polyolefin outer sheath. According to the high temperature resistant cracking resistant nuclear power single-core control cable, the low smoke halogen-free environment-friendly radiation resistant cross-linked polyolefin outer sheath is employed, a cracking phenomenon of the cable in a use process can be effectively prevented, the performance of the cable is prevented from being affected, and the cable has the advantages of reasonable and simple structure, easy manufacture, low cost, and good service performance.
Description
Technical field
The utility model relates to the field of nuclear power cable, especially a kind of high temperature resistant cracking resistant type nuclear power list core control cables.
Background technology
The cable for nuclear power station product is divided into nuclear power station power cable, control cable for nuclear power station, nuclear power station instrument measurement cable, nuclear power station compensating cable by purposes; Be divided into K1 class cable, K2 class cable, K3 class cable by the installation region, K1 class and K3 class cable belong to 1E level cable for nuclear power station.
The cable that uses in the nuclear power station must meet the following conditions: have reliable useful life, thermal stability, good electric property, high flame resistance, resistance to elevated temperatures, radiation resistance.Because the cable that uses at present, it in use produces cracking phenomena easily, and holds requirement that can't stand intense radiation, and resistance to elevated temperatures is poor, when running into fire, makes troubles for disaster relief personnel, thus the potential safety hazard of causing.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of high temperature resistant cracking resistant type nuclear power list core control cables, its project organization rationally and can cracking resistance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high temperature resistant cracking resistant type nuclear power list core control cables, comprise the cable core conductor, described cable core conductor is coated with insulating barrier, insulating barrier is coated with tincopper fuse wire braided armor, tincopper fuse wire braided armor is coated with the environment-friendly high fire-retardant oxygen barrier layer, the environment-friendly high fire-retardant oxygen barrier layer is coated with the radioresistance layer, and the radioresistance layer is coated with low-smoke halogen-free environment radiation hardness cross-linked polyolefin oversheath.
In order to increase insulation property, improve coefficient of safety, the material of described insulating barrier is that IXPE is made.
In order to increase capability of resistance to radiation, described radioresistance layer is low-smoke halogen-free environment radiation hardness cross-linked polyolefin radiating layer.
The beneficial effects of the utility model are: described a kind of high temperature resistant cracking resistant type nuclear power list core control cables, adopt low-smoke halogen-free environment radiation hardness cross-linked polyolefin oversheath, can prevent effectively that the phenomenon that ftractures from use appearring in cable, avoid affecting the performance of cable, it is rational in infrastructure simple, easy to manufacture, cost is low, and serviceability is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the overall structure schematic diagram of a kind of high temperature resistant cracking resistant type nuclear power list core control cables described in the utility model.
Accompanying drawing acceptance of the bid score state as follows: 1, cable core conductor, 2, insulating barrier, 3, tincopper fuse wire braided armor, 4, the environment-friendly high fire-retardant oxygen barrier layer, 5, the radioresistance layer, 6, low-smoke halogen-free environment radiation hardness cross-linked polyolefin oversheath.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of high temperature resistant cracking resistant type nuclear power list core control cables as shown in Figure 1, comprise cable core conductor 1, it is the insulating barrier 2 that IXPE is made that cable core conductor 1 is coated with material, insulating barrier 2 is coated with tincopper fuse wire braided armor 3, tincopper fuse wire braided armor 3 is coated with environment-friendly high fire-retardant oxygen barrier layer 4, it is the radioresistance layer 5 that low-smoke halogen-free environment radiation hardness cross-linked polyolefin is made that environment-friendly high fire-retardant oxygen barrier layer 4 is coated with material, and radioresistance layer 5 is coated with low-smoke halogen-free environment radiation hardness cross-linked polyolefin oversheath 6.
A kind of high temperature resistant cracking resistant type nuclear power list core control cables of the present utility model utilizes low-smoke halogen-free environment radiation hardness cross-linked polyolefin as the material of oversheath, can avoid cable the phenomenon of splitting, the useful life of having improved cable in use to occur.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
