额定电压0.6/1kV聚氯乙烯绝缘电力电缆 PVC insulated power cables with rated voltages 0.6/1kV 一、产品用途Products application 本产品适用于配电网、工业装置等领域，用于固定敷设在交流50Hz、额定电压0.6/1kV的电力输配电线路上，主要功能是输送电能。本产品为通常条件下使用的产品，不适用一些特殊条件的场合，如架空、水下、船用、海底、核电站等。 阻燃聚氯乙烯绝缘电缆适用于具有阻燃要求的场合。 耐火聚氯乙烯绝缘电缆适用于地下铁道、地下商场、大型购物中心、高层建筑等人口稠密、通风受限的场合。Technique features 本产品电缆除具有可靠的电气性能外，还具有较强的防止化学腐蚀性，耐酸碱和有机溶剂，电缆不受敷设落差的限制，可在任何落差甚至垂直的场合敷设。 Standards7 GB/T 12706.1-2002 额定电压1 kV(Um1.2 kV)到35 kV(Um40.5 kV)挤包绝缘电力电缆及附件第部分额定电压 kV(Um=1.2 kV)和3 kV(Um=3.6 kV)电缆Power cables with extruded insulation and their for rated voltages from 1kV(Um=1.2kV) up to 35kV(Um=40.5kV) Part?1:Cables for rated?voltages?of 1kV(Um=1.2kV) and 3 kV（Um kV）额定电压1 kV(Um1.2 kV)到30 kV(Um36 kV)挤包绝缘电力电缆及附件第2部分额定电压 kV(Um=1.2kV)和3 kV(Um=3.6kV)电缆Power cables with extruded insulation and their for rated voltages from 1kV(Um=1.2kV) up to 35kV(Um=40.5kV) Part?1:Cables for rated?voltages?of 1kV(Um=1.2kV) and 3 kV（Um kV）Conductor of Cables GB/T19666-2005 阻燃耐火电线电缆通则 GB/T 19666-2005 General Rules of flame-retarding and fireproof cables 四、使用特性Operating characteristics 额定电压Rated Voltage 电缆额定电压U0/U(Um)为：0.6/1(1.2)kV Rated Voltage of cable U0/U(Um)：0.6/1(1.2)kV 其中：Notes： U0：电缆设计用的导体对地或金属屏蔽之间的额定工频电压； Rated A.C. Voltage between conductor and ground/metal screen; U：电缆设计用的导体间的额定工频电压； Rated A.C. Voltage between conductors Um：设备可承受的“最高系统电压“的最大值。 The maximum system voltage which the equipments can be beared 电缆的额定电压应适合电缆所在系统的运行条件。为了便于选择电缆，将系统划分为下列三类： The rated voltage of cable shall be applicable to system operation condition where the cable lain in. According to cable selecting, the system will be described as 3 types as follow: ——A类：任一相导体与地或接地导体接触时，能在1min内与系统隔离。 System category A —When any phase of cable conductor is contacting with earth conductor, the cable will be isolated with the system. ——B类：可在单相接地故障时作短时运行，但任何情况下不宜超过8h，每年接地故障总持续时间不宜超过125h。 System category B ─The system is allowed to run for 8 hours, when the single-phase earth fault is existing. And the total earth-fault tim
