摘　　要：采用同样架设多回架空输电线路方式是解决输电走廊紧张矛盾的根本措施之一,阐述了采用这一技术的技术要点,包括杆塔结构、耐雷水平、线路保护故障判别、绝缘子型式的选择与环境影响、运行与检修特点等。并详细介绍了国内外应用情况。The power transmission technology of muhi-circuit lines on the same tower is one of the fundamental measures for solving the lack of transmission lines corridors. The technology is expatiated, including the structure of towers and poles, the lightning impulse withstand level, differentation of the line protection faults, selection of insulator types, the environmental effect, and characteristics of operation and maintenance. The application of this technology at home and abroad is introduced in detail.
