Abstract
The invention discloses a cable used for nuclear power station measurement. The cable is composed of a conductor, an inner insulating layer, an outer insulating layer, an inner lapped covering layer, a filling layer, an outer lapped covering layer, an inner jacket layer, a shielding layer, an inner sheath and an outer sheath. The inner insulating layer and the outer insulating layer are sequentially arranged outside the conductor in an extrusion mode, the inner jacket layer is arranged outside the outer lapped covering layer in an extrusion mode, and the shielding layer is arranged outside the inner jacket layer in an extrusion mode. The cable is good in flexibility, malleability and bendability, capable of working in a high-temperature environment and high in corrosion resistance, and is not oxidized when laid in a severe environment.
Description
Technical field
The present invention relates to field of cables, relate in particular to a kind of nuclear power station measurement cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable using in each field is all very high to the requirement of the flexibility of cable, ductility and bendability.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of corrosion resistance strong, under rugged environment, lay non-oxidizing nuclear power station measurement cable.
The present invention takes following technical scheme to realize: a kind of nuclear power station measurement cable, it is comprised of conductor, inner insulating layer, external insulation layer, interior lapping layer, packed layer, outer lapping layer, inner cushion layer, screen, inner sheath and oversheath, described conductor is extruded with described inner insulating layer and external insulation layer outward successively, described outer lapping layer is extruded with described inner cushion layer outward, and described inner cushion layer is extruded with described screen outward.
Described inner sheath material is perfluoroethylene-propylene.
The present invention has following beneficial effect in sum: the present invention has good flexibility, ductility and bendability, and can bear under hot environment and work, and corrosion resistance is strong, under rugged environment, lays and is not oxidized.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, conductor; 2, inner insulating layer; 3, external insulation layer; 4, interior lapping layer; 5, packed layer; 6, outer lapping layer; 7, inner cushion layer; 8, screen; 9, inner sheath; 10, oversheath.
Embodiment
As shown in Figure 1, a kind of nuclear power station measurement cable, it is comprised of conductor 1, inner insulating layer 2, external insulation layer 3, interior lapping layer 4, packed layer 5, outer lapping layer 6, inner cushion layer 7, screen 8, inner sheath 9 and oversheath 10, outer described inner insulating layer 2 and the external insulation layer 3 of being extruded with successively of described conductor 1, outside described outer lapping layer 6, be extruded with described inner cushion layer 7, outside described inner cushion layer 7, be extruded with described screen 8.
Inner sheath 9 materials are perfluoroethylene-propylene.
Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in claim scope of the present invention.
