| 摘 要： | 电力工程中控制电缆截面选择不当会带来很多安全隐患。通过分析因电缆截面选择不当造成的事故，总结了如何正确选择控制电缆截面。指出设计时应对电缆截面进行严格核算；现场解决控制电缆截面过小引起问题时，可考虑采取缩短电缆长度的解决方案。

| Abstract: | Selection of an inappropriate control cable cross-section will bring about a lot of hidden troubles for power projects.Based on an analysis of the accidents caused by inappropriate selection of control cable cross-sections,some methods are proposed in this paper on how to select appropriate control cable cross-sections.It is proposed that the cross-sections of control cables should be checked strictly in design,and the on-site solution to the undersize cross-sections of control cables is to shorten the cabl... |
