Description
Technical field：
The present invention relates to cable, mainly a kind of floating nuclear power plant is with 1E grades of K1 class cables.
Background technology：
At present, the autonomy-oriented and degree domestic of China's floating nuclear power plant device therefor are still very low, and the construction of nuclear power station
The problem of quality is again the public's most general concern with safety.Therefore, the Chinese government adheres to that production domesticization will all the time in development nuclear energy
The basic principle of " safety first, quality first " is obeyed, that is, is digesting and assimilating the basis of external state-of-the-art quality and safety standard
On, develop the localized equipments of China.This project construction exactly realizes Nationalization of Nuclear Power Equipment service for China.With《Core is pacified
Full planning》Issuing and implementation, security and the higher three generations's nuclear power station of economy will substitute two generation units, therefore research and development manufacture is marine
Floating nuclear power plant will comply with nuclear power development tendency with 1E grades of K1 classes cables, capture nuclear grade cable commanding elevation, with economic and society
Double benefit.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of floating nuclear power plant cable, to solve prior art presence
Technical problem.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of floating nuclear power plant cable, includes the multiple conductors being made up of many stranded bunchys of tinned copper wire, and it is special
Levy and be：Irradiation crosslinking halogen-free polyolefin inner insulating layer and irradiation crosslinking halogen-free polyolefin flame-retardant have been respectively coated by outside each conductor
External insulation layer, has also been respectively coated by high-temperature resistant membrane outside the irradiation crosslinking halogen-free polyolefin flame-retardant external insulation layer of each conductor
Glass fibers are coated with jointly outside lapping layer and the outer lapping layer of high-temperature fibre, the outer lapping layer of high-temperature fibre of the multiple conductor
Tie up and non-hygroscopic bittern-free flame-proof material packed layer, non-hygroscopic are provided with grid cloth inner liner, fiberglass gridding cloth inner liner
Marine glue is filled with bittern-free flame-proof material packed layer；Described fiberglass gridding cloth inner liner is coated with by Tarpauling
Overlapping wrapped composition around packaging waterproof layer, Tarpauling be coated with successively outside packaging waterproof layer alumina silicate fibre braiding jacket layer,
Irradiation crosslinking halogen-free polyolefin flame-retardant external sheath layer；In described Tarpauling overcoat is woven around packaging waterproof layer and alumina silicate fibre
Mixture filled with waterproof paste and water-proofing powder is provided with packed layer, packed layer between layer.
2nd, a kind of floating nuclear power plant cable according to claim 1, it is characterised in that：In alumina silicate fibre
Braiding jacket layer before irradiation crosslinking halogen-free polyolefin flame-retardant external sheath layer with having additional water-blocking buffer layer..
Conductor of the present invention uses the 2nd class tinned copper conductor.
Innovative point of the present invention：
（1）Designed using double-layer insulating structure.Internal layer is extruded using high electrical performance irradiation crosslinked polyolefin insulating material, and outer layer is adopted
Extruded with irradiation flame-proof cross-linking crosslinked polyolefin insulating material.
（2）Using frequency variable synchronous, online outside diameter measuring technology and digital temperature control, extruder head is using double-deck self centring skill
Art, effectively solves the problems, such as the manufacturing process core shift that insulate, can carry out cable insulation wire core double layer structure and extrude simultaneously.
（3）It is cable needs compact conformation, outer for the floating nuclear power plant harsh use environment of 1E grades of K1 class cables
Footpath is small, it is lightweight the features such as, cable filling extrudes structure using squash type, reduces the external diameter increase caused by strip is filled, carries
High cable roundness, effectively prevents cable insulated wire cores under high temperature and high pressure environment to be subjected to displacement and influence properties of product.
（4）We are more for bittern-free flame-proof material filler in processing performance, cause material to be flowed in extrusion
Property it is poor, frictional heat is big, and temperature requirement precision is high, influences the phenomenons such as stretching and the tensile strength of finished cable, carries out emphasis tackling key problem,
And the technical support of material producer is achieved, extruder head and mould are improved, material property has been grasped, makes each of trial product
Item performance reaches code requirement.
It is an advantage of the invention that：
Floating nuclear power plant cable increase of the present invention has multiple waterproof layer structure, and good water-proof effect also has additional high temperature resistant
Lapping layer, is effective to ensure that the properties of insulated wire cores at high operating temperatures, also has significantly to cable overall performance
Lifting.
