Abstract
The utility model discloses a three-shielding cable for nuclear power, which comprises an inner conductor, and is characterized in that the inner conductor is coated with a foam insulation layer, the foam insulation layer is coated with an inner shielding layer, the inner shielding layer is coated with a middle shielding layer, and the middle shielding layer is coated with an outer shielding layer. The three-shielding cable for nuclear power has the advantages that since the middle shielding layer made of pure iron is added, the three-shielding cable for nuclear power has the features of high radiation resistance, high temperature resistance, abrasion resistance, oil resistance, high mechanical strength, high reliability, good shielding performance, low attenuation, and the like.
Description
Technical field
The utility model relates to cable, is a kind of nuclear power shielded type cable specifically.
Background technology
Nuclear power 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. with the shielded type cable product.Because special applied environment is all had relatively high expectations to shielding properties and the intensity of cable, existing shielded type cable is owing to adopt double shield, and so screen in not adopting is poor effect.
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 three shielded type cables comprise inner wire, and described inner wire coats foaming insulation layer outward, and described foaming insulation layer coats internal shield outward, screen in the outer coating of described internal shield, and described middle screen coats outer shielding layer outward;
Described internal conductor material is copper cash;
Described foamed insulation layer material is SiO
3
Described internal shield material is copper;
Polymeric barrier layer materials is pure iron in described;
Described outer shielding layer material is stainless steel.
The utility model has the advantages that: owing to increased the middle screen of pure iron, therefore, anti-high radiation, high temperature resistant, wear-resisting, oil resistant, mechanical strength height, reliability height, advantages of good shielding performance, decay are low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
