Abstract

The invention discloses an instrumentation cable for a nuclear power plant. The instrumentation cable for the nuclear power plant comprises a cable inner core and a cable outer layer. The cable inner core is formed by wrapping a plurality of insulation power cable cores around a silvered copper wire stranded conductor. A gap in the cable inner core is provided with a polyethylene insulation layer. Each insulation power core is formed by wrapping a silicone rubber insulation layer on four aluminum alloy conductors in an extruded mode. A wrapping tape layer is wrapped around the cable inner core. The cable outer layer is formed by sequentially wrapping a piece of semiconductor water-blocking tape, a tinned copper wire weaving shielding layer and a fluorinated ethylene propylene jacket layer on the wrapping tape layer in an extruded mode from interior to exterior. The instrumentation cable for the nuclear power plant has the advantages of being low in smoke, free of halogen, retardant to flame, resistant to fire, good in shielding performance and long in service life.

Description

A kind of used in nuclear power station instrument and meter cable
Technical field
The present invention relates to field of cables, relate in particular to a kind of used in nuclear power station instrument and meter cable.
Background technology
Utilize nuclear energy power generation to become countries in the world and solve the important channel of 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.
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 used in nuclear power station instrument and meter cable.
The present invention 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 present invention has following beneficial effect in sum: this cable tool has low cigarette, Halogen, the feature that fire-retardant, fire-resistant, shielding properties is good, long service life.
