Abstract
Disclosed in the utility model is an instrument cable for nuclear power station. The cable comprises a cable inner core and a cable outer layer; the cable inner core is formed by extruding a silver-plated copper wire stranded conductor by a plurality of insulated power wire cores; and a polyethylene insulating layer is arranged in the gap inside the cable inner core. each of the insulated power wire cores is formed by extruding four aluminium alloy conductors with a silicone rubber insulating layer. A wrapping layer wraps the outside of the cable inner core. Besides, a semi-conductive water-blocking belt, a tinned copper wire braiding shielding layer, and a tetrafluoroethylene-hexafluoropropylene copolymer sheath successively extrude the wrapping layer from inside to outside to form the cable outer layer. The provided cable has characteristics of low smoke, halogen-free performance, flame retardance, fire resistance, good shielding property, and long service life.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of used in nuclear power station instrument and meter cable.
Background technology
Utilize nuclear energy power generation to become the important channel that countries in the world solve energy problem, the pith of Ye Shi China energy strategy, active development nuclear energy cable is one of important component part realizing nuclear energy domestic manufacture of key equipment.The coastal area that electric load is concentrated, nuclear power station will become the mainstay of electric structure.Build nuclear power station cable type, quantity used various, it not only has the general characteristic of common cable, also will have low cigarette, Halogen, the characteristic such as fire-retardant, and have specifically environment resistant.And the poor-performings such as the anti-flammability of the domestic cable for nuclear power station of prior art, thermal endurance, radiation resistance, and useful life is short.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of used in nuclear power station instrument and meter cable.
The utility model takes following technical scheme to realize: a kind of used in nuclear power station instrument and meter cable, comprise cable inner core and cable outer layer, cable inner core extrudes a silver-gilt copper wire stranded conductor by several insulated power cores and forms, and in cable, in the gap of in-core, is provided with polyethylene layer; Described insulated power core is to be extruded on four aluminium alloy conductors and to be formed by silicone rubber insulation layer, and insulated power core inside is provided with fire-resistant packed layer; Lapping layer is wrapped outside cable inner core; Described cable outer layer is to be extruded on lapping layer and to form from inside to outside successively by semiconductive waterstop, tinned copper wire woven shield, perfluoroethylene-propylene sheath.
The specification of described silver-gilt copper wire stranded conductor is that 24 cross-sectional areas are stranded the forming of silver-gilt copper wire of 1.5 square millimeters.
The utlity model has in sum following beneficial effect: this cable tool has low cigarette, Halogen, the feature that fire-retardant, fire-resistant, shielding properties is good, long service life.
