1KV交联聚乙烯绝缘电力电缆载流量

1、0.6/1kV交联聚乙烯绝缘电力电缆载流量（含普通型，阻燃型，耐火型，无卤低烟阻燃型）1 .产品特点及用途交联聚乙烯绝缘电力电缆具有高机械强度、耐环境应力好、优良的 电气性能和耐化学腐蚀等特点，重量轻，结构简单，使用方便。本产品 适用于交流额定电压 Uo/U为0.6/1kV及以下的输配电线路上。阻燃电力电缆的主要特点是电缆不易着火或着火时延燃仅局限在 一定范围内，适用于电缆敷设密集程度较高的发电站、地铁、隧道、高 层建筑、大型工矿企业、油田、煤矿等场所。耐火电力电缆的主要特点是电缆除了能在正常的工作条件下传输电力外，电缆在着火燃烧时仍能保持一定时间的正常运行，适用于核电站、地铁、隧道、高层建筑

2、等与防火安全和消防救生有关的地方。低烟无卤阻燃型电缆的特点是电缆不仅具备阻燃性能，而且具有低发烟性和无害性（毒性和腐蚀性较小），适用于对电缆阻燃、烟密度、 毒性指数等有特别要求的场所，如地铁、隧道、核电站等。2 .产品标准本产品按GB/T 12706-2002或IEC 60502标准组织生产，还可按用户要求的其他标准生产。阻燃型电缆除按上述标准外，其阻燃性能按GB/T18380.3-2001标准规定分成A B、C三种不同的阻燃类别，A级类别的阻燃性能最优， 用户可根据需要选用。耐火型电缆的耐火性能应符合GB/119216.21-2003。无卤低烟阻燃型电缆按企业标准组织生产，阻燃性能按GB/T

3、18380.3-2001标准规定分为 A B C种不同的阻燃类别，烟浓度通 过GB/T17651-1998规定的试验，PH值及导电率应符合 GB/T17650.2-1998 的规定。3 .产品型号普通型电缆型号YJM YJLV交联聚乙烯绝缘聚氯乙烯护套电力电缆YJY YJLY交联聚乙烯绝缘聚乙烯护套电力电缆YJV22 YJLV22交联聚乙烯绝缘钢带铠装聚氯乙烯护套电力电缆YJV23 YJLV23交联聚乙烯绝缘钢带铠装聚乙烯护套电力电缆YJV32 YJLV32交联聚乙烯绝缘细钢丝铠装聚氯乙烯护套电力电缆YJV33 YJLV33交联聚乙烯绝缘细钢丝铠装聚乙烯护套电力电缆阻燃型电缆型号在普通型电力电
