【摘要】In allusion to conglutination of vertically arranged double bundled conductors of several 220 kV overhead transmis-sion lines in Guangdong power grid which may cause great influence on safe and reliable operation of the power grid,this pa-per studies and analyzes reasons and influence factors for conglutination by developing field test on conglutination of the con-ductor. Initial intervals,spans of different sub-conductors and observation files of working strength were selected and under different running currents,values of intervals were measured,meanwhile,temperature of conductors and pictures of corona before and after the conglutination were recorded. Test results indicate that under the same running currents,the congluti-nation of double bundled sub-conductors were mainly affected by initial intervals,spans and working strength,a certain de-gree of temperature rise occurs after the conglutination and obvious noise of mechanical oscillation appears. In order to pre-vent conglutination,technical measures were proposed aiming at different design,construction and operating stages.%针对近年广东电网多条220 kV 架空输电线路出现垂直排列双分裂导线粘连的问题，通
