The results show that the peak tension in the conductor of upper crossarm at suspension point exceeds the design value. Insulator rupture has no effect on tower component of upper crossarm, but it has significant influence on insulator tension of upper crossarm. The lower limit of longitudinal unbalanced tension of two and more than two bundle conductor is relatively small. Insulator rupture should be taken into account in the design for overhead transmission lines.
