编制阐明Directions:
1.低烟无卤阻燃聚烯烃绝缘地铁地道专用电缆接连负载电流是根据IEC-287电缆载流量核算规范进行核算的,并经过批改确认。
Continuous loading current of cable is calculated per IEC-287
2.此地铁地道专用电缆的长时间作业温度不超越70℃。
Long-term working temperature is not more than 70℃.
3.布线方法分为触摸与非触摸两种,其中非触摸指电缆间的彼此间隔大于二倍的电缆外径.触摸即指电缆彼此靠在一同或彼此距离小于二倍的电缆外径。
Laid method:contact and non contact.Non contact laid means the distance between the laying cable is more than 2 times of cable O.D.Contact laid means the distance between the laying cable is not more than 2 times of cable O.D.
4.周围环境温度以40℃作为基准温度。
Environment temperature is supposed 40℃ as basic temperature
