Abstract
The utility model discloses a high-fire-retardant environmental-friendly power cable for nuclear power stations. The high-fire-retardant environmental-friendly power cable is characterized by the inclusion of at least cable core, insulation layers, a glass fiber layer and a halogon-free jacket layer, wherein the insulation layer is made of polylactide; the halogon-free jacket layer is made of halogon-free high-fire-retardant materials; and the insulation layers are wrapped on the outer surfaces of the cable core; the cable core with the insulation layers on 2 to 5 outer surfaces thereon is wrapped in the glass fiber layer, and the halogon-free jacket layer is arranged on the outer side of the glass fiber layer. The high-fire-retardant environmental protection power cable for nuclear power stations provided by the utility model has strong radiation and oxidation resistance, high flame retardance, low smoke, innocuousness and environmental protection, can resist high temperature of 1000 DEG. C above, bear the impact of nuclear radiation and high temperature, can be used for ensuring the safety of the nuclear pile, and can be applied to such places with high requirements on the safety and environmental protection performance as power plants, metallurgical plants, petrochemical plants, underground transportation facilities, etc.
Description
Technical field
The utility model relates to the cable technology field, is specifically related to a kind of high flame retardant nuclear power environmental-friendly power cable.
Background technology
The existing cable product that is applicable to the nuclear power field, great majority exist shortcomings such as radiation resistance is poor, oxidative resistance is poor, fire resistance difference.Simultaneously, the production of nuclear power cable has quite serious pollutant sources, can produce a large amount of public hazards when its manufacturing, use and waste treatment.Particularly, increased the danger of disaster hidden-trouble and fire owing to a large amount of uses of electric wire.After breaking out of fire, flame can spread along cable rapidly, and a large amount of smog and HCL poisonous gas that the electric wire burning produces can not only cause people's death by suffocation, hinder fire fighter's disaster relief, and modernized electric equipment had great corrosion, cause spot fire easily.The place more to some modern facilities, the loss of the secondary disaster that fire causes even surpass direct fire damage.
So in the cables manufacturing industry, the problem that improves the feature of environmental protection, oxidative resistance, radiation resistance, fail safe and the heat-resisting quantity difference of existing nuclear power cable has more and more caused people's attention.Yet up to now, still there is not a kind of perfect nuclear power cable can satisfy above-mentioned requirements.The utility model proposes at the problems referred to above.
The utility model content
The purpose of this utility model provides a kind of high flame retardant nuclear power environmental-friendly power cable, it is strong that this cable has radiation resistance, oxidative resistance is strong, high flame retardant, can anti-1000 degrees centigrade high temperature, the impact that can bear nuclear radiation and high temperature, low cigarette, nontoxic, environmental protection, can be used for ensureing the safety of nuclear reactor, also can be widely used in power plant, metallurgy, petrochemical industry, underground transportation facilities etc. the demanding place of safety and environmental protection performance.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: a kind of high flame retardant nuclear power environmental-friendly power cable is provided, it is characterized in that: include core, insulating barrier, glass layer and Halogen restrictive coating at least; Described insulating barrier is made by the polylactide material; Described Halogen restrictive coating adopts the halogen-free high flame-retardant plastics to make; Described insulating barrier is wrapped up in the outer surface that is attached to core; Be enclosed with 2-5 outer surface in the described glass layer and wrap up in core with insulating barrier, the glass layer arranged outside has the Halogen restrictive coating.
According to high flame retardant nuclear power environmental-friendly power cable provided by the utility model, it is characterized in that: the rounded or sector structure of the cross section of described core.
According to high flame retardant nuclear power environmental-friendly power cable provided by the utility model, it is characterized in that: also be provided with a screen between described glass layer and the Halogen restrictive coating, described screen is the rare earth galvanized steel wire netting.
In sum, it is strong that high flame retardant nuclear power environmental-friendly power cable provided by the utility model has radiation resistance, oxidative resistance is strong, high flame retardant, can anti-1000 degrees centigrade high temperature, the impact that can bear nuclear radiation and high temperature, low cigarette, nontoxic, environmental protection, can be used for ensureing the safety of nuclear reactor, also can be widely used in power plant, metallurgy, petrochemical industry, underground transportation facilities etc. the demanding place of safety and environmental protection performance.
