摘　　要：天津陈塘庄电厂-迎丰变220 k V线路工程,是国网天津市电力公司全面贯彻全寿命周期管理理念的输电线路建设的先进典型。本文对工程的设计创新实践成果进行介绍,主要设计亮点有:新型节能导线应用、良导体地线和OPGW均采用分段绝缘单点接地运行方式、导线呈"双曲线"紧缩型布置杆塔规划设计、双回路(鹰嘴)蝶形钻越塔、大截面角钢应用、后注浆灌注桩、栈桥施工方案等。Tianjin ChenTang Zhuang Power Plant -YingFeng Substation 220 kV transmission line project, is an advanced and typical transmission line construction of State Grid Tianjin Electric Company, which implements the lifecycle management idea completely. This paper introduces the design innovation outcomes of this project, and the main design highlights contains： the application of the new energy-saving wire, adopting sectional insulation and single point grounding operation mode of good conductor shied line and（OPGW） Opticle fibre composite overhead ground wire, the tower planning design of hyperbolic-compact layout of wires, the application of double-circuit（chickpea） butterfly drill towers,and large section angle steel and post grouting for cast-in-situ pile, construction scheme using trestle bridge.
