Overhead conductor is the most important equipment material of transmission line. It works in the natural environment for a long time. Its performance and life are restricted by the environment, and the influence of environmental corrosion on conductor is the most obvious. To understand the Corrosion-proof steel core characteristics of high-anticorrosive conductors suitable for coastal and high pollution areas, the accelerated comparative tests of steel core corrosion between aluminium clad steel wire, Zn-5% A1-Re alloy coated steel wire and galvanized steel wire were carried out. The results show that, after 1000 hours of neutral salt spray corrosion, the galvanized layer of galvanized steel wire almost disappeared, and obvious corrosion acceleration occurred, the aluminum clad steel wire was only corroded on the outer layer of aluminium, Zn-5% A1-Re alloy coated steel wire were only corroded on the surface layer, and the transition layer was not corroded. All of them have strong corrosion resistance, and the overall corrosion resistance is better than the galvanized layer of galvanized steel wire.

During prototype ET period,some high-hard-plate may be machined by handwork.In order to verify the diversification and trend of the high-hard-plate material performance after it fired,the DOE analysis method was used to analyze and calculate the performance diversification trend of the fired plate,and the main factor that affecting the performance of material made sure.So that an instruction can be afforded for prototype ET and verifying work.

工程样车试制阶段会对部分高强板进行手工敲制及制作工作，为了验证高强板在受火作业后材料性能发生的变化以及变化趋势，利用DOE正交表分析方法对板材受火作业后材料性能的变化进行分析计算，并确定影响材料性能变化的主要因素，从而为工程样车试制、验证工作提供指导。
