Nuclear energy is a kind of cleaning and the safe and reliable energy, can effectively alleviate energy demand and money that China becomes increasingly conspicuous at present
Source, communications and transportation, the contradiction of environmental protection, are also an important channel for solving China's energy potential collision hazard.At present
Go into operation and in the major nuclear power stations built, the K3 class nuclear grade cables only outside containment have started to progressively domesticize, and harsh and unforgiving environments
With（K1 classes）Cables most all relies on import, according to the construction demand of Chinese following nuclear power, nuclear grade cable wide market.
From the point of view of world wide, Asia is still the center of Nuclear Electricity development.Three generations's nuclear power harsh and unforgiving environments are developed to use
（K1 classes）1E grades of nuclear grade cable markets will be produced material impact, and realize and substitute similar imported product, realize nuclear power by nuclear grade cable
Key technology domesticizes, and development and national security to social economy have great significance, while being expected to realize to outgoing
Mouthful, lift the competitiveness of domestic nuclear power international market.Instrument is with cable suitable for instrument, instrument and other electric equipments
Signal is transmitted and control circuit, in nuclear power industry, and instrument cable will focus on the security of signal transmission and control, and tool is not required nothing more than
There are preferable insulating properties, shielding, also require that the properties of cable in high temperature environments meet design requirement.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of instrument cable for nuclear power station, to solve the skill of prior art presence
Art problem.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of instrument cable for nuclear power station, includes the multiple conductors being made up of many stranded bunchys of tinned copper wire, and its feature exists
In：Described conductor has four and symmetrically spread configuration, and the symmetrical center positions of four conductors are provided with cylindrical rubber
Glue support frame；Irradiation crosslinking halogen-free polyolefin inner insulating layer and irradiation crosslinking halogen-free polyene have been respectively coated by outside each conductor
The fire-retardant external insulation layer of hydrocarbon, high temperature resistant has also been respectively coated by outside the irradiation crosslinking halogen-free polyolefin flame-retardant external insulation layer of each conductor
It is coated with jointly outside lapping layer and the outer lapping layer of high-temperature fibre in film, the outer lapping layer of high-temperature fibre of the multiple conductor
Metal supporting rings, are coated with high-temperature resistant coating, the metal supporting rings and high-temperature fibre on the surface of metal supporting rings
Web inner cushion layer is provided between outer lapping layer, be also wrapped on outside metal supporting rings by alkali-free glass fiber cloth it is overlapping it is wrapped constitute it is outer
Aluminium-plastic tape screen layer, irradiation crosslinking halogen-free polyolefin flame-retardant are coated with successively outside lining, the outer lining of the alkali-free glass fiber cloth
External sheath layer；Filling non-hygroscopic bittern-free flame-proof material in packed layer, packed layer is provided with described web inner cushion layer.
A kind of described instrument cable for nuclear power station, it is characterised in that：Many steel cables are additionally provided with the packed layer.
Conductor of the present invention uses the 5th class tinned copper conductor.
The present invention is applied to inside and outside three generations's nuclear power plant containment shell on 300/500V measurement thermocouples, and the cable passes through alloy
The characteristics of conductor resistance temperature coefficient is small is accurately measured, and insulation and sheath can meet -15 DEG C of cryogenic conditions, with bunchy
The excellent properties of fire-retardant A classes, are subjected to the simulation heat ageing and radiation test of 150 DEG C, 2376 hours of the temperature of equivalent 60 years, its
Service life reaches 60 years, reaches advanced international level.
Innovative point of the present invention：
（1）Carry out material beta ray and gamma-rays transfer test at home first；
Due to the limitation of current experimental condition, β ray tests device is still difficult to carry out radiation aging experiment to batch cable, to ensure
The continuity of experiment, my company carries out β rays and gamma-rays transfer test to identical material, and model is calculated with reference to center group heap work
Enclose, experiment draws β rays and gamma-rays conversion proportion, LOCA radiation agings carried out using whole cable of conversion proportion relation pair,
Ensure test validity.
（2）Under equal conditions carry out heat ageing and the comparative experiment of simulating piece bunchy burning, checking before and after radiation aging
Heat ageing and the influence of radiation aging factor pair fire retardant mechanism；
For checking heat ageing and the influence of radiation aging factor pair fire retardant mechanism, examination list of the research and development cable in nuclear safety office tissue
Under the witness of position and designing unit, heat ageing and simulating piece bunched burning test before and after radiation aging are under equal conditions carried out,
Result of the test meets design and test program requirement.
（3）Optimize product structure, increase high temperature resistant lapping layer；
This time the insulation of research and development core is extruded using irradiation polyolefin bilayer, it is ensured that its electrical property meets design requirement, but because of polyene
The resistance to elevated temperatures of hydrocarbon material is relatively low, to ensure that cable is normally used under nominal situation and DBA and AG operating modes, in insulated wire cores
The upper selection increase wrapped Rotating fields of high temperature resistant, effectively ensure that the properties of insulated wire cores at high operating temperatures meet design and wanted
