Technical field
The present invention relates to a kind of cable, relate in particular to a kind of computer cable for nuclear power plant.
Background technology
The present used cable of nuclear power station is in cost consideration and mostly is single-layer shield individual layer sheath, this just causes the anti-interference and wear-resistant degree of cable not high, especially it requires higher to shield effectiveness the nuclear power station computer with cable, any problem can not occur, and existing single-layer shield individual layer protective-cover type structure can't meet the demands.
Summary of the invention
Purpose of the present invention is exactly not good with its screening ability of cable in order to solve present nuclear power station computer, problems such as wear-resistant degree is low, provide a kind of and have simple in structurely, easy to use, can effectively improve the computer cable for nuclear power plant of advantages such as cable antijamming capability.
For achieving the above object, the present invention adopts following technical scheme:
A kind of computer cable for nuclear power plant, conductor meets GB3956, and the outer wall wrap insulate layer of conductor also places in the low-smoke non-halogen flame-retardant obturator, and described obturator outer wall is provided with cable duplex sheath and heterogeneous cable double layer screen; Two core conductors are one group simultaneously, and their outside is provided with heterogeneous conductor double layer screen layer.
Described cable duplex sheath is made up of internal layer sheath and outer protective sleeve; Wherein, the internal layer sheath is the fluoroplastics sheath, and outer protective sleeve is the low-smoke halogen-free polyolefin sheath.
Described heterogeneous cable double layer screen comprises that wrapped total shielding of internal layer and outer braid always shield, and the wrapped total shield pack of internal layer is rolled on the low-smoke non-halogen flame-retardant obturator; Wherein the wrapped total shielding of internal layer is an aluminium-plastic tape, and the total shielding of outer braid is copper wire or tinned copper wire braiding.
Described insulating barrier comprises primary insulation and outer layer insulation; Wherein, primary insulation is crosslinked crosslinked polyetylene insulated layer; Outer layer insulation is the low-smoke halogen-free polyolefin insulating barrier.
Described heterogeneous conductor double layer screen layer comprises that wrapped branch shielding of internal layer and outer braid divide shielding; Wherein, the wrapped branch shielding of internal layer is aluminium-plastic tape, and outer braid divides shielding to be copper wire or tinned copper wire braiding.
Computer cable for nuclear power plant of the present invention all adopts double hyer insulation, and internal layer is crosslinked cross-linked polyethylene insulating material, and skin is the low-smoke halogen-free polyolefin Insulation Material; Sheath adopts duplex sheath, and internal layer is fluoroplastics, and skin is the low-smoke halogen-free polyolefin protective cover material, and performance is with reference to other patents.
Its screen adopts double layer screen, that is: the aluminium-plastic tape shielding adds copper wire or tinned copper wire braid shielded, the same control cable of its superior performance
Double layer screen
Changed the single-layer shield of prior cable, the antijamming capability to external world that the shielding of double-deck different materials has strengthened cable has also increased the mechanical performance of cable, uses drainage thread to make shield effectiveness more reliable.
Duplex sheath
The protective action of the existing sheath in the past of duplex sheath has strengthened the weatherability of cable again, makes the environment for use of cable more extensive.
Aluminium-plastic tape
The wrapped shielding of aluminium-plastic tape contains again and moulds the band mechanical stress promptly by the shielding properties of aluminium strip, makes screen firm more, reliable.
The tinned copper wire braiding
Make the screen of cable have corrosion-resistant, oxidation resistant characteristic, in the useful life of the cable shield of increase, make the performance shielding action that screen more can be permanent.
Insulation Material adopts cross-linked polyethylene insulating material, has reduced dielectric loss in use, has strengthened electrical property, makes transmission signals more stable and undistorted, thereby ensures the effective transmission of cable.
The invention has the beneficial effects as follows: simple in structure, cost is low, good in anti-interference performance, and weatherability is strong, and accommodative ability of environment is strong, reliable operation.
