6-35kV电力电缆载流量.doc
6kV35kV高压电缆载流量表6kV35kV交联聚乙烯绝缘电力电缆交联聚乙烯绝缘电力电缆是采用化学方法或物理方法,使聚乙烯分子由线型分子结构转变为三维网状结构,由热塑性的聚乙烯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温为90，较低绝缘电缆、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。一、适用范围 本产品适用于固定敷设在交流50Hz额定电压为35kV与以下输配电线路上使用二、使用特性· 工频额定电压U0/U为3.6/6kv26/35kv。· 电缆导体的最高允许工作温度：90。· 短路时最长时间不超过5s电缆导体的最高温度不超过250。· 电缆敷设时环境温度应不低于0。· 电缆弯曲半径：三芯电缆不小于电缆外径15倍；单芯电缆不小于电缆外径20倍。三、规格型号：额定电压6kV35kV
