Abstract
The utility model discloses a high-strength full-shielding pulse resistant ultrahigh frequency cable for nuclear power; the cable comprises an inner conductor, and the inner conductor is wrapped in sequence by an insulation layer, a taped covering, a first braid layer, a first taped covering, a second braid layer, a second taped covering, a third braid layer, a third taped covering, a fourth taped covering and a EP rubbers sheath; the cable is characterized by employing shielding layers of different metals and employing a scheme that the braid layers and the taped coverings are alternately arranged, radiations generated by different electricions are shielded, and shielding effect is greatly improved because of multi-layer arrangement; and the cable is high radiation resistant, high temperature resistant, wear resistant, is full-shielding and pulse resistant, and is high in tensile strength, mechanical strength and reliability.
Description
Technical field
The utility model relates to cable, is the anti-pulse hyperfrequency of a kind of high strength full-shield cable specifically.
Background technology
The anti-pulse hyperfrequency of high strength full-shield cable product is used for the instrument external connection line of the inner High Radiation Area of nuclear-power reactor and the internal connection line of instrument etc.Because special applied environment is all had relatively high expectations to shielding properties and the intensity of cable, existing shielded type cable does not adopt the multilayer screen layer, so poor effect owing to adopt double shield.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of shielded type cable with good shielding properties and mechanical performance, can satisfy the specific (special) requirements of the internal connection line of the instrument external connection line of the inner High Radiation Area of nuclear-power reactor and instrument.Concrete scheme is as follows:
A kind of nuclear power anti-pulse hyperfrequency of high strength full-shield cable, comprise inner wire, it is characterized in that: described inner wire is coated insulation layer, lapping layer, first braid, first lapping layer, second braid, second lapping layer, the 3rd braid, the 3rd lapping layer, the 4th lapping layer, ethylene-propylene rubber sheath successively outward;
Described internal conductor material is silver-coated copper wire;
Described insulating layer material is the ethylene-propylene rubber of anti-irradiation;
Described lapping layer material is the individual layer polyimide film;
The described first braid material is silver-coated copper wire;
The described first lapping layer material is the individual layer stainless steel band;
The described second braid material is silver-coated copper wire;
The described second lapping layer material is the individual layer stainless steel band;
Described the 3rd braid material is silver-coated copper wire;
Described the 3rd lapping layer material is double-deck plastic-aluminum combined film; Described the 4th lapping layer 10 materials are double-deck polyimide film.
Advantage of the present utility model: owing to adopted the screen of different metal, and the scheme of employing braid and the alternate setting of lapping layer, the radiation that different electron ion is produced produces shielding, and because multilayer setting, improve shield effectiveness greatly, had anti-high radiation, high temperature resistant, wear-resisting, full-shield, tensile strength height, anti-pulse, mechanical strength height, high reliability features.
