Abstract
The invention discloses a special instrument cable for a nuclear power plant, and relates to the technical field of manufacture of cables for the nuclear power plant. The special instrument cable comprises two twisted cable cores, wherein a first polyester tape tapped covering, a tinned copper wire braiding total shielding layer, an oxygen insulation layer and an irradiation cross-linked halogen-free low-smoke flame-retardant polyolefin outer jacket layer are arranged on the outer sides of the two twisted cable cores sequentially; a filler layer is arranged between the two twisted cable cores and the polyester tape tapped covering; each cable core comprises two insulation conductors which are twisted oppositely into a group; a second polyester tape tapped covering and an aluminum plastic composite tape shielding layer are arranged sequentially on the outer side of each group of insulation conductors; each insulation conductor comprises a copper conductor, and a cross-linked polyethylene inner insulation layer and a high-flame-retardant irradiation cross-linked polyolefin outer insulation layer are arranged on the outer side of each copper conductor sequentially. The special instrument cable for the nuclear power plant is reasonable in structure, novel in materials, easy to produce and manufacture, low in cost, good in usability and suitable for places such as the nuclear power plant, a subway, a station, an airport, a substation, a hotel, a hospital and the like.
Description
Technical field
The present invention relates to cable for nuclear power station manufacturing technology field, particularly relate to the extraordinary instrument cable of a kind of used in nuclear power station.
Background technology
It is reported, by in China's " new forms of energy 12 development plan " of putting into effect the end of this year, nuclear power developing thinking will be adjusted, adhering under safe prerequisite, nuclear power will be rapidly developed, and will reach 4,300 ten thousand kilowatts, to the year two thousand twenty to installation in 2015,9,000 ten thousand kilowatts will be reached, and strive reaching 100,000,000 kilowatts.These nuclear power stations will adopt AP1000 technology comprehensively, and the power that it has stronger nature closes succinct design, has the construction cost that more reliable security performance is less.
For AP1000 technology, the supporting instrument cable in generation Ⅲ nuclear power station requires the useful life possessing more than 60 years, and has the performance of cracking resistance, low cigarette, Halogen, fire-retardant, radiation hardness, resistance to LOCA.At present, instrument cable capability of resistance to radiation, useful life, anti-cracking performance etc. on market do not reach requirement, main dependence on import mostly, and therefore, research and development generation Ⅲ nuclear power station instrument cable is extremely urgent, shoulders heavy responsibilities.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide reach a kind of useful life more than 60 years, electrical property, fire-retardant, resistance to long term heat ageing, radioresistance, resistance to LOCA the extraordinary instrument cable of used in nuclear power station of function admirable.
The present invention includes two strands of mutual stranded cores, outside described two strands of mutual stranded cores, set gradually the first polyester belt lapping layer, tinned copper wire braided overall-shielding layer, oxygen barrier layer and irradiation crosslinking halogen-free low-smoke flame-proof polyolefin external sheath layer; Between described two strands of mutual stranded cores and polyester belt lapping layer, packed layer is set; Per share described core comprises two strand insulation conductors respectively, and described every two strand insulation conductor pair twists in groups, set gradually the second polyester belt lapping layer and aluminium-plastic tape screen respectively often organizing outside insulated electric conductor; Described every root insulated electric conductor comprises copper conductor respectively, sets gradually crosslinked polyethylene inner insulating layer and flame resistance irradiation cross-linked polyolefin external insulation layer outside every root copper conductor.
The present invention is rational in infrastructure, material is novel, manufacture easily, cost is low, serviceability is good, there is reliable useful life, high flame resistance, high electrical performance, high radiation resistance and excellent physical and mechanical properties, be applicable to the fields such as nuclear power station, subway, station, airport, transformer station, hotel, hospital.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes two strands of mutual stranded cores 1, outside two strands of mutual stranded cores 1, set gradually the first polyester belt lapping layer 2, tinned copper wire braided overall-shielding layer 3, oxygen barrier layer 4 and irradiation crosslinking halogen-free low-smoke flame-proof polyolefin external sheath layer 5; Between two strands of mutual stranded cores 1 and polyester belt lapping layer 2, packed layer 6 is set; Per share core 1 comprises two strand insulation conductors 7 respectively, and every two strand insulation conductor 7 pair twists in groups, set gradually the second polyester belt lapping layer 8 and aluminium-plastic tape screen 9 respectively often organizing outside insulated electric conductor 7; Every root insulated electric conductor 7 comprises copper conductor 10 respectively, sets gradually crosslinked polyethylene inner insulating layer 11 and flame resistance irradiation cross-linked polyolefin external insulation layer 12 outside every root copper conductor 10.
