三、使用特性 Product features
1、电缆导体最高允许工作温度:正常运行时90 ,短路时(最长5 s)为250
Max. admissible temperature for conductor90 under normal running condition250 during short circuitmax. duration not exceeding 5s.
2U0按系统接地故障持续时间不同分为两类,见表3-1
1类电缆——用于单相接地故障时间每次不大于1分钟的系统,亦可用于最长不超过8 h,每年累计不超过125 h的系统。
2类电缆——用于接地故障时间更长的系统,对电缆绝缘性能要求较高的场合,也应采用第2类。
U0 according to system ground fault duration divided into two categories, see Table 3-1.
Class 1 cable -- time for single-phase ground fault is less than 1 minute each time the system can be used for no longer than 8 h, 125 h per year does not exceed the total system.
Category 2 cable -- longer for ground-fault system, the cable insulation applications requiring high performance, it should be Category 2.
