摘　　要：220kV耐张复合绝缘子双串在沿海一些严重污秽地区得到了局部应用,但一直未得到大范围推广,主要是对耐张复合绝缘子双串在运行过程中发生机械性能下降或因内部缺陷导致断裂等问题存在疑虑。分别以2×LGJ-400/35型双分裂导线和1×LGJ-400/35型单导线为例,简要分析220kV耐张复合绝缘子串可行性,并进行优化设计,达到可偏转、安全强度高、少维护、免清扫。Some 220 kV composite insulators were used for tension strings in heavy pollution coastal area, it was not popularized up to now because the mechanical performances dropped or the insulator was broken caused by itself defection in operation. The feasibility on 220 kV composite insulator for tension strings was analyzed with 2×LGJ-400/35 double split line and 1×LGJ-400/35 line, and the optimization design for 220 kV composite insulator tension strings was carried out to have the merits of deflection,high safety, less maintenance, and without cleaning.
