At present, with the need of economic development, China’s power industry is committed to the study of compact and narrow basal transmission tower. This paper, establishes the ANSYS finite element mixed model with beam and truss of the new tower-type (500kV compact narrow beam transmission tower), uses subspace iteration method to obtain the first 20 modes of the model of 500kV compact narrow beam transmission tower and its free vibration period, and compares with the result which are commonly used by China’s power industry and the result from the first free vibration periods experience formula provided by “Architectural structure load regulating”. The preliminary conclusion was obtained that China’s power industry experience formula is still valid in CNBTT actual engineering design.
