谈耐火电缆与耐火封闭母线的区别与应用

On the differences between the fire-resistant cable and the fire-resistant enclosed busbar

结合工作经验,分别介绍了耐火电缆和耐火封闭母线的组成及适用范围,并阐述了两者的区别及应用情况,得出在线路输送电流不是很大时用耐火电缆较合适,在线路输送电流较大时用耐火封闭母线较合适的结论。

Combining with the working experiences, the paper respectively introduces the components and the application .scopes of the fire-resistant cable and the fire-resistant enclosed busbar, illustrates their differences and applications, and concludes that it is more fitful to use the fire-resistant cable when the input current is not large, and it is more appropriate to use the fire-resistant enclosed busbar when the output current is large.
