The composite insulating cross-arm has the characteristics of light weight,high strength,high insulation reli-ability and excellent lightning protection effect,and is gradually being popularized and applied in 10 kV distribution lines.Focusing on the three issues of structural design,durability research and performance testing of the tension com-posite insulating cross-arm for distribution network,firstly,we reviewed the development status of the 10 kV distribu-tion network tension-resistant composite insulating cross-arm and pointed out the necessity of research.And then we discussed the design basis,existing design types,durability research progress represented by fatigue and vibration ag-ing,and key performance testing and evaluation.At the same time,we analyzed the existing problems and difficulties to be solved.Finally,we made the summary and prospect in combination with the application,and with a view to pro-viding reference for the structure optimization,performance improvement and subsequent large-scale application of the distribution network tension composite insulating cross-arm.
