overhead transmission line
3.The papers depend on the practice of hydrologial survey in overhead transmission line large crossing engineering on the Yellow River downstream,analyze the effect of the Yellow River downstream’s flood,alluvial,ice run etc. factors on overhead transmission lines engineering.
4.The paper discussed live working on the first 220kV compact overhead transmission line in our country,calculating the over voltage and safe distance,which made the live working on this line possible.
5.In order to achieve more consistent structural reliabilities across materials, American Society of Civil Engineers (ASCE) developed the Manual 74, "Guidelines for Transmission Line Structural Loading" and the IEC60826, "Design Criteria of Overhead Transmission Lines".
6.Simulated Calculation and Analysis Research about Lightning Overvoltage on High Voltage Overhead Power Transmission Line Ⅱ: Simulated Calculation and Analysis about Ligtning proof Abilit and rate of Trip by Lightning Strike of Power Transmission Line
7.The conductor ACSR 720/50 used in ±500 kV DC transmission line connecting Longquan and Zhengping for the Three Gorges Power Transmission Project is the overhead conductor in China having the largest cross section up to now.
8.Construction of Three Gorge Power Transmission Project Promotes Technical Advance of Overhead Cable Line in China
