核电站电缆料的研究进展

依据核电站电缆的种类,介绍了核电站电缆料的种类、性能、生产工艺和国内外的研究现状。研究发现,制备核电站电缆绝缘料主要用交联聚乙烯(XLPE)和硅橡胶(或硅橡胶复合材料),此两种原料具有优良的耐热性、电绝缘性、耐低温性、耐化学性和良好的耐辐射性;核电站电缆料应具有低烟无卤、耐阻燃性和耐环境性能;其制备方法主要是挤出法,此方法生产工艺简单、成本低。最后展望了核电站电缆料的发展趋势。

Study and Progress of Nuclear Power Cable Materials

According to the type of nuclear power cable,the classification,performance,process technology and research status at home and abroad on the nuclear power cable materials are introduced.It is found that the insulation material of the nuclear power cable is mainly cross-linked polyethylene(XLPE) and silicone rubber(or silicone rubber composites),with which have thermal properties,electric insulation,low-temperature resistance,chemical and radiation resistance;and has low smoke non-halogen,flame and environment resistance;its main process is extrusion method,which is a simple production technology and cost low.At last,the development trend of nuclear power cable materials is previewed.
