JFEYH高压电机引接线




交联聚乙烯绝缘电力电缆是采用化学方法或物理方法, 使聚
乙烯分子由线形分子结构转变为三网状结构, 由热塑性的聚乙烯  JFEYH高压电机引接线
变成热固性的交联聚乙烯,从而提高了聚乙烯的耐老化性能、机
械性能和耐环境能力,并保持了优良的电气性能。
交联聚乙烯绝缘电力电缆导体的允许长期最高工作温度为
90℃,较之绝缘电缆、聚氯乙烯绝缘电缆和聚乙烯绝缘电缆高,
且具有重量轻、结构简单、使用方便、耐化学腐蚀和敷设不受落
差限制等优点。
For XLPE insulated power cable, either chemical method or physicalJFEYH高压电机引接线
method is employed to transform the molecular structure of PE from
chain into three-dimensional network,i.e. thermoplastic PE is transformed
into thermosetting XLPE. After cross-linking,the thermal and mechanical
properties of PE have been gratly improved while its excellent electrical
property are still retained.
The maximun permissible operating temperature of the conductor
of a XLPE insulated power cable is 90℃ which s higher than that
ofpaper,PVC or PE insulated power cable.The cable has the advantage
of simplicity in construction,lightness in weight,convenience in application
besides its xecellent electrical,thermal,mechanical and anti-chemical
corrosion properties.It can also be laid with no limitation of level defference
along the route.
