Abstract
The utility model relates to a radiation resistant fireproof nuclear power cable comprising a cable core conductor which is coated by an inorganic material insulation layer which is coated by a flame retardant layer. A conductor belting layer is arranged outside the flame retardant layer. A filling material is filled between the conductor belting layer and the flame retardant layer. The conductor belting layer is coated by an aluminium magnesium alloy braided layer which is coated by an outer sheath whose surface is coated by a fireproof layer. According to the radiation resistant fireproof nuclear power cable, through the above design structure, the radiation resistance performance and fireproof performance of the cable can be effectively raised, and the cable has good flame retardant performance.
Description
Technical field
The utility model relates to the field of nuclear power cable, especially a kind of radiation hardness fire-type nuclear power power cable.
Background technology
The cable that nuclear power station uses all is normal cable, generally be not less than 40 years the useful life of cable, radioresistens can be high, operating temperature is not less than 90 ℃, cable also should have good fire resistance and high temperature resistant, anti-cooling, but because in the special area of some nuclear power station, its radioactive intensity is considerably beyond general zone, it easily affects the normal performance of cable; In the situation that some burst fire, it easily causes the damage of cable, can not satisfy the nuclear power station instructions for use so far away.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of radiation hardness fire-type nuclear power power cable, its project organization rationally and can have simultaneously a height fire protecting performance radiation-resistant.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of radiation hardness fire-type nuclear power power cable, comprise the cable conductor conductor, described cable conductor conductor is coated with the inorganic material insulating barrier, the inorganic material insulating barrier is coated with flame-retardant layer, the flame-retardant layer outside is provided with the conductor belting layer, be filled with inserts between described conductor belting layer and the flame-retardant layer, the conductor belting layer is coated with the almag braid, the almag braid is coated with oversheath, is coated with fireprotection layer on the surface of outer sheath.
In order to improve anti-flammability, the material of described inserts is that low smoke halogen-free flame-retardant polyolefin is made.
In order to improve fire line, the material of described inorganic material insulating barrier is that fire-resistant silicon rubber is made.
The beneficial effects of the utility model are: described a kind of radiation hardness fire-type nuclear power power cable, this laminar project organization can effectively improve radiation resistance and can improve fire protecting performance, and have good fire resistance.
