英文摘要: In this research, several kinds of common conductive materials were compared with copper on material properties, including conductivity, heat stability, corrosion resistance and mechanical properties. These results were used to analyze the possibility of replacement for copper by common conductive materials in actual environmental conditions of cable grounding wire. The results showed that aluminum was the suitable substitute for copper in cable grounding wire. Next to copper, aluminum performed best on most of the material properties and cost performance among the samples. Due to the lower secondary value of aluminum, it had contributed to decrease the stolen rate of cable grounding wire if the copper was replaced by aluminum. It also could relieve the pressure of transmission line...
中文摘要: 通过对比几种常见导电材料和铜材料的导电性能、热稳定性、耐腐蚀性和机械性能优劣,并结合铜质接地线实际使用环境对各种常见导电材料替代铜质接地线的可能性进行理论验证,结果显示:各种常见的导电材料中,采用铝代替铜作为接地线是较为合适的,铝的多项材料性能和性价比仅次于铜,而二次价值较低的铝若应用于电缆接地线中将有助于降低接地线被盗的概率,降低线路运维单位防盗工作的压力并间接减少线路运行隐患,具有一定的研究价值和社会效益。
