编制说明Directions:
1.低烟无卤阻燃聚烯烃绝缘地铁隧道专用电缆连续负载电流是依据IEC-287电缆载流量计算标准进行计算的,并通过修正确定。
Continuous loading current of cable is calculated per IEC-287
2.此地铁隧道专用电缆的长期工作温度不超过70℃。
Long-term working temperature is not more than 70℃.
3.布线方式分为接触与非接触两种,其中非接触指电缆间的相互距离大于二倍的电缆外径.接触即指电缆相互靠在一起或相互间距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
