Description
Technical Field
The utility model relates to a radiation cable technical field especially relates to a radiation-resistant cable.
Background
Traditional cable all has the sinle silk to and the cladding constitutes at the insulating layer of sinle silk outer peripheral face, and traditional cable all uses the design for conventional environment, and the unsuitable occasion that has nuclear radiation is used, and its reason is: in the case of nuclear radiation, the insulating layer is damaged by long-term nuclear radiation irradiation, so that the conducting characteristics of the wire and the cable are influenced, and the reliable transmission of signals is influenced. Therefore, the service life of the conventional cable is short when the cable is used in a nuclear radiation environment.
Disclosure of Invention
To the not enough of above-mentioned prior art, the utility model provides a radiation-resistant cable solves above-mentioned problem.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a radiation-resistant cable, includes oversheath layer, armor, first radiation protection layer in proper order, winds covering, inner sheath layer, filling layer and conductor from outside to inside, the conductor outside is from inside to outside in proper order cladding insulating layer, second radiation protection layer, the filling layer parcel in the second radiation protection layer is outside, the inner layer structure of cable is by the whole cladding of outer structure in proper order.
Among this technical scheme, set up the armor in outer sheath layer, can provide sufficient hardness and rigidity for the cable, through setting up first radiation protection layer and second radiation protection layer, can effectively avoid nuclear radiation to the influence of cable, the insulating layer can make the cable fire-resistant.
Preferably, the insulating layer is a ceramic insulating layer.
Thus, the ceramic insulating layer has good heat and corrosion resistance properties while providing insulation protection.
Preferably, the first radiation protection layer and the second radiation protection layer are radiation protection silver fiber layers.
In this way, the cable can be used in a high radiation environment.
Preferably, the inner sheath layer and the outer sheath layer are made of polytetrafluoroethylene materials.
Thus, the polytetrafluoroethylene has excellent chemical stability, corrosion resistance, sealing property, high lubrication non-sticking property, electrical insulation property and good ageing resistance, and the cable is safer.
Preferably, the wrapping layer is one of a halogen-free low-smoke high-flame-retardant wrapping tape and an alkali-free glass fiber wrapping tape.
Thus, the flame retardancy of the cable can be improved.
Preferably, the armor layer is a galvanized steel strip.
Thus, the galvanized steel strip is processed by the procedures of pickling, galvanizing, packaging and the like of common steel strips, and has good corrosion resistance.
Preferably, the filling layer is an asbestos flame-retardant filling layer.
Thus, the asbestos flame-retardant filling layer is applied to filling of the multi-core cable so as to enable the cable to be fire-resistant and round.
The utility model has the advantages that:
a radiation-resistant cable, through setting up first radiation protection layer and second radiation protection layer, can effectively avoid the nuclear radiation to the influence of cable to can prolong the life of cable in nuclear radiation environment, the occasion that is particularly suitable for nuclear power station etc. and has the nuclear radiation uses.
