耐火交联聚乙烯绝缘聚氯乙烯护套电力电缆,属于耐火电缆,在火灾发生时,保持一定时间的运行,即保持电路的完整性,有一定时间的供电能力,可敷设在室内、隧道内及管道中、可承受一定的敷设牵引,但电缆不能承受外力作用,单芯电缆不允许敷设在磁性材料管道中。
Fire-resistant XLPE insulated PVC sheathed power cable belongs to fire-resistant cable. When fire occurs, it keeps running for a certain time, that is to say, it keeps the integrity of the circuit and has a certain power supply capacity for a certain time. It can be laid indoors, in tunnels and pipelines, and can withstand certain laying traction, but the cable can not withstand outside. Force action, single core cable is not allowed to be laid in magnetic material pipeline.
如需承受机械外力作用加绕钢带铠装,适用于特殊要求场合,如带容量电厂、核电站、高层建筑。YJV交联聚乙烯绝缘聚氯乙烯护套电力电缆,不具有阻燃和耐火性,可敷设在室内、隧道内、管道中,可经受一定的敷设牵经,但电缆不能承受外力作用,单芯电缆不允许敷设在磁性管道中,如需承受机械外力作用加绕钢带铠装。
If it needs to withstand mechanical external force and wrap steel belt armor, it is suitable for special occasions, such as power plants with capacity, nuclear power plants, high-rise buildings. YJV cross-linked polyethylene insulated PVC sheathed power cables are not flame retardant and fire-resistant. They can be laid indoors, in tunnels and in pipelines. They can withstand certain laying stretches, but the cables can not withstand external forces. Single-core cables are not allowed to be laid in magnetic pipelines. If they need to withstand external mechanical forces and wrapped with steel band armor.
