Cable, the construction of cable provided by the utility model is simple, environmentally protective, flexibility is good, maintenance and maintenance are simple.
Technical solution
In order to achieve the above technical purposes, a kind of radiation hardness cable for nuclear power station provided by the utility model, feature exist
In: the cable includes conductor thread core, winds polyamide tape wrapping layer one outside the conductor thread core, the polyamide tape around
Ceramic silicon rubber insulating layer is wrapped up outside covering one, winds polyamide tape wrapping layer outside the Ceramic silicon rubber insulating layer
Two, the polyamide tape wrapping layer two winds fiberglass braided layer outside, and the fiberglass braided layer surface sprays to be formed
Polyimide solution coating.
Further, the conductor thread core is made of the copper conductor or nickel plated copper conductor of sub-thread or multiply.
Further, the polyamide tape wrapping layer one and polyamide tape wrapping layer two are respectively outside conductor thread core
Outside Ceramic silicon rubber insulating layer, wrapped overlap rate is 20%~40%.
Further, the Ceramic silicon rubber insulating layer with a thickness of 0.2~3.0mm.
Further, the count of the fiberglass braided layer is 85%~95%.
Beneficial effect
A kind of radiation hardness cable for nuclear power station provided by the utility model, long service life, structure is simple, and flexibility is good,
Conducive to safeguarding and overhauling, using multilayer polyimide wrapping layer, the radiation resistance of cable is improved.Using Ceramic silicon rubber
As insulating layer, so that cable has flame-retardant performance.Modeling is replaced with fiberglass braided layer and polyimide solution coating
Expect sheath and protective metal shell.Since glass fibre is inorganic material, radiation hardness, ageing-resistant, temperature resistant grade etc. are better than plastic sheath,
And flexibility is better than protective metal shell, overhauls and easy to maintain.
