The utility model discloses the superior performance is stable, long service life.
Description
Technical field
The utility model is related to pressure crosslinking electricity in a kind of electric wire, more particularly to a kind of generation Ⅲ nuclear power station special type
Cable.
Background technology
It is the security reliability for improving nuclear power after Japanese " Fukushima " nuclear power plant accident, it is managing according to State Council in 2012
Meeting has to comply with third generation safety standard for the requirement of Construction of Nuclear Electricity, from now on China's new nuclear power unit.Require nuclear power
There is the probability of reactor core serious damage in unit, be below 10 a ten thousandth heap years, and radioactive material Environment release will be less than million
/ a pile year.Third generation advanced version nuclear power station, with the less construction cost of more reliable security performance, each state is all positive
Build.Therefore, generation Ⅲ nuclear power station has most vast potential for future development.
Generation Ⅲ nuclear power station midium voltage cable is a critical electrical part of nuclear power station, be nuclear power station nervous centralis and
" blood vessel " of normal operation is maintained, is mainly used in the electrical power transmission system at generation Ⅲ nuclear power station.Because nuclear power station typically build edge in
Haiti band, these regional weather moistenings, air humidity is big, if without good waterproof construction, the easy shape in wet environment
Into cable water tree, this strong influence cable performance and service life.Therefore, research and develop pressure in the special type of generation Ⅲ nuclear power station to hand over
Connection cable is necessary.
Utility model content
The utility model is stablized to solve problem above there is provided a kind of superior performance, the third generation core of long service life
Crosslinked cable is pressed in the special type of power station.
The technical solution of the utility model is：Described cable includes three insulated wire cores, three described insulated wire cores
Between be provided with packed layer, waterstop lapping layer is set outside three described insulated wire cores and constitutes cable core, described cable core is outer wrapped
Halogen glass fiber tape flame-retardant layer, extrudes halogen-free flame retarding cross-linked polyethylene outer jacket, every insulated wire cores outside described flame-retardant layer
Include conductor, conductor shield, insulating barrier, insulation screen, wrapped semiconductive water blocking layer and metallic shield successively from the inside to the outside
Layer.
Described conductor be tin-coated copper monofilament it is stranded press form.
Described conductor Jing three-layer co-extruded cross-linkings unit extrudes successively conductor shield, crosslinked polyetylene insulated layer, insulation
Screen layer.
Described metal screen layer is copper strip shielding layer.
Described packed layer is the rubber filling layer that blocks water.
Described waterstop lapping layer is the compound waterstop of water-swellable, wrapped using bilayer, and per layer to put up rate not little
In 30%.
Described flame-retardant layer adopts oxygen index (OI) wrapped for the Halogen glass fiber tape bilayer of 0.25mm more than 50, thickness, often
Layer puts up rate not less than 60% so that cable often locates Halogen glass fiber tape not less than 4 layers.
The utility model can not only meet the requirements that nuclear power plant environment is used, and fill out due to being provided with cable and block water
Fill layer and water blocking layer, make cable have it is excellent block water and water tree resistant property, when cable insulation is used in a humid environment
The generation of water tree is avoided, the stability and security of medium voltage line is improve, cable service life is extended, confession is reduced
Electric cost.
