摘　　要：介绍了750kV电网工程建设中LGJK-300／50扩径导线的采用原理、研制方法和应用情况。在考虑地理环境和工程应用等诸多因素的情况下，通过与常规导线电气、机械和经济指标对比分析，阐明了扩径导线的技术性能优良并节约铝材20％～30％，是建设“环境友好型，资源节约型”的典型示范，为扩径导线技术应用和推广提供了有利的证明，为超特高压输电工程建设提供了技术借鉴。The adopted theory, development method and application status of LGJK-300/50 expanded conductor in 750 kV power grid are introduced. Compared with conventional conductors on electrical, mechanical and economical index when taking various factors into consideration, such as geographical conditions and engineering applications, expanded conductor has excellent technical characteristics, and it can save 20%-30% aluminum material. So it is a typical demonstration of environment-friendly, resource- saving construction. This paper can be a convincing proof for technical application and popularization of expanded conductors, and a reference for super/extra-high-voltage power transmission project construction.
