二、执行标准 Standards
本产品按照等效采用IEC 60502标准的GB/T 12706标准进行生产,阻燃类电缆符合国标GB/T 19666。
This product is used in accordance with IEC 60502 standard is equivalent to GB / T 12706 standard for production. Flame-retardant cable meets the national standard GB / T 19666.
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 conductor:90 ℃ under normal running condition,250 ℃ during short circuit(max. duration not exceeding 5s).
2、U0按系统接地故障持续时间不同分为两类,见表3-1
第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。
第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.

3、电缆在环境温度不低于0 ℃条件下敷设时,无须预先加热,电缆的敷设不受落差限制。敷设时最0.小弯曲半径:
Cable of not less than 0 ℃ ambient temperature under the conditions of laying, without pre-heating, cable laying is not dro restrictions. Minimum bending radius when laid:
单芯电缆(Single-core cable) 20(D+d)±5%mm
多芯电缆(Multi-core cable) 15(D+d)±5%mm
式中(wher):D——电缆的实际外径(The actual diameter of the cable),mm
