8.7/10kv电力电缆YJV-1*35
6kV~35kV 中低压铜芯及铝芯交联聚乙烯绝缘电力电缆(YJV电缆,YJV22电缆,YJLV电缆,YJLV22电缆) XLPE Insulated Power Cable |
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摄氏度,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。 26/35KV电力电缆,18/30KV交联电缆,12/20KVYJV电缆,8.7/15KVYJV22电缆线,6/10KV铝芯交联电缆线,3.6/6KVYJLV单芯电缆 中低压交联电缆产品标准 Standard 本产品按GB12706《额定电压35V及以下铜芯、铝芯塑料绝缘电力电缆》标准生产,同时还可根据用户需要按国际电工委员会推荐标准IEC、英国标准、德国标准及美国标准生产。 The product is manufactured according to the standard of《GB12706 or IEC、BS、DIN and ICEA upon request. 适用范围 Applications 本产品适用于工频额定电压3.6/6kv~26/35kv输配电线路作配送电能子用。 The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv~26/35kv. 使用特性 Operating characteristics · 工频额定电压U0/U为3.6/6kv~26/35kv。 Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv. · 电缆导体的最高允许工作温度:90℃。 Max.admissible operating temperature of the conductor:90℃. · 短路时(最长时间不超过5s)电缆导体的最高温度不超过2500C。 Max. short-circurt temperature of conductor shall not exceed 2500C.
