Description
Technical field
The utility model relates to a kind of cable, is the strong fire-retardant anti-interference power cable of a kind of 1E grade K 3 genus nuclear power plant specifically.
Background technology
Generally, 1E level K
3The bunchy firing resistance of class power cable for nuclear power plant requires to reach the requirement of category-B or higher category-A, thereby the fire resistance that forms cable material is had higher requirement; Due to the impact that is subject to the Flame Retardancy energy, cable is difficult to reaching fire-retardant other requirement of category-A level of bunchy in general composition structure.And, do not have the cable of armour poor to the protective capacities of electricity/magnetic interference, under special circumstances, such as: when lightning, circuit on/off, thereby be easier to be subject to the interference in extraneous electricity/magnetic field and cause the misoperation of relevant device to cause the accident.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of have better fire resistance and 1E level K anti-electric, the magnetic interference performance
3The strong fire-retardant anti-interference power cable of class used in nuclear power station.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of 1E level K
3The strong fire-retardant anti-interference power cable of class used in nuclear power station, comprise cable core, in the outside of described cable core, is coated with successively lapping layer, the first oxygen barrier layer, armour, the second oxygen barrier layer, oversheath; Between described cable core and described lapping layer, be provided with filling.
Further, described cable core has four, and each cable core comprises conductor, the first insulating barrier and the second insulating barrier from inside to outside successively.
As the further improvement of above-mentioned insulating barrier, the first insulating barrier is the IXPE insulating barrier; The second insulating barrier low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layer.
As the further improvement of above-mentioned conductor, described conductor is the tin-plating round copper wire of strands.
In the utility model, described the first oxygen barrier layer and the second oxygen barrier layer are high flame retardant oxygen barrier material and extrude and form.
In the utility model, described armour is wrapped the forming in double-deck galvanized steel strip gap.
In the utility model, described oversheath is that the low-smoke non-halogen flame-retardant of anti-irradiation thermosetting polyolefin jacket material extrudes and forms.
Beneficial effect: compared with prior art; after the utility model has the advantages that the employing technique scheme; more common core has better fire resistance and anti-electric, magnetic interference performance with power cable; under the home condition and under the safe shutdown earthquake load, still can carry out the function of its regulation; fire and extraneous electricity/magnetic field fault is disturbed stronger opposing protective capability is arranged, can carry out better or supporting reactions control, waste heat is got rid of and radioactive substance contains three basic security functions and prevent gentle solution accident.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further and explained.
As shown in Figure 1, a kind of 1E level K
3The strong fire-retardant anti-interference power cable of class used in nuclear power station, comprise 4 cable cores, each cable core comprises conductor 1 and insulating barrier 2, and above-mentioned insulating barrier 2 adopts double-decker, be that insulating barrier is divided into inner insulating layer and external insulation layer, in conductor 1 outside, extrude successively from inside to outside above-mentioned inner insulating layer and external insulation layer; Then use low-smoke non-halogen flame-retardant double-coated alkali-free glass silk ribbon that 4 cable cores are together wrapped, the wrapped like this low-smoke non-halogen flame-retardant double-coated alkali-free glass silk ribbon in cable core outside namely forms lapping layer 4, between the second insulating barrier of each cable core and lapping layer 4, is provided with low-smoke non-halogen flame-retardant without rock rope filling 3; In the outside of lapping layer 4, be coated with successively the first oxygen barrier layer 5, armour 6, the second oxygen barrier layer 7, oversheath 8.
Above-mentioned conductor 1 is the tin-plating round copper wire of strands; Inner insulating layer is the IXPE insulating barrier; External insulation layer low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layer.The first oxygen barrier layer 5 and the second oxygen barrier layer 7 are high flame retardant oxygen barrier material and extrude and form, and high flame retardant oxygen barrier material is mainly usingd the macromolecular materials such as polyolefin as carrier, and a large amount of high-performance refractory agent has been added in the inside, and the main component of fire retardant is metal hydroxides; This high flame retardant oxygen barrier material can produce a large amount of water when burning, and forms cellular tissue, plays the effect of isolation flame and cooling.Adopt double-deck galvanized steel strip gap wrapped as armour 6; Oversheath 8 forms for the low-smoke non-halogen flame-retardant of anti-irradiation thermosetting polyolefin jacket material extrudes.
Above material used is commercially available prod.
The above is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
