Problems solved by technology

Therefore, if polyether ether ketone material is selected as the insulation and sheath of power cables, if conventional technical solutions, conventional cable structures and production processes are adopted, the cable cannot be bent due to the high hardness of this material, which directly leads to failure. use

Abstract

The invention relates to a 1E grade K1 class flexible power cable for a nuclear reactor, in particular to a 1E grade K1 class power cable which can be used in a nuclear island (a nuclear power station, a nuclear submarine, and the like). The cable comprises a flexible conductor, a polyether-ether-ketone flexible compound insulated layer, a metal shield (optional) and a polyether-ether-ketone flexible compound protective covering (optional) from inside to outside. The invention solves the technical problem on how to provide the 1E grade K1 class power cable for the nuclear power station, in particular to the 1E grade K1 class power cable which can be used in the nuclear island. The cable has the advantages that the service life of the cable can reach 50 years under the condition that the working temperature is 250 DEG C for a long term, and the maximum accumulative radiation dose is 1.0*10<7>Gy; the relative humidities of service environment are respectively 90 percent under a normal working condition and 100 percent under an accidental working condition; the cable is halogen free, flame retardant, nontoxic and environmentally friendly; the cable can pass a vertical bundling combustion test; and the properties of the cable are greatly improved, meanwhile, due to the flexibility and the bandability of the cable, the cable is greatly convenient to lay and mount (particularly in occasions with space limit, such as the nuclear submarine, and the like).

Description

technical field [0001] The invention relates to 1E-class K1 flexible power cables for reactors, in particular to 1E-class K1 power cables that can be used inside nuclear islands (nuclear power plants, nuclear submarines, etc.). Background technique [0002] As of 2009, my country's nuclear power installed capacity was only 9.08 million kilowatts. According to the medium and long-term development plan for nuclear power formulated by my country in 2007, it is planned that nuclear power construction will reach 40 million kilowatts by 2020 (accounting for only 4% of the total installed capacity). However, I am trapped in the fact that the actual nuclear power construction is developing extremely rapidly, and this nuclear power installed capacity will be completed in advance of the "Twelfth Five-Year Plan", a full five years in advance. At present, there are 10 projects under construction in my country, and 21 are under construction. It is estimated that before 2020, 27 new nucle...
