Calculation and Analysis of the Lower Curved Arm Structure of the Cat-Head Type Straight Tower
Cat-Head Type Straight Tower are widely used in single-circuit AC transmission lines,and their tower head structure is relatively complex.The structure of the lower cross-arm part is particularly important for the entire pole tower.In this paper,the finite element software was used to model a module straight pole tower of 110 kV voltage level and conduct an in-depth analysis of the calculation results.The analysis results show that,after verification through the typical design revision work,reasonable planning of the Cat-Head Type Straight Tower's lower cross-arm structure can effectively reduce the angle steel specifications of the external main materials of the lower cross-arm,decrease the number of segments,connection diagonals,node plates,and bolts,thereby effectively reducing the overall weight of the pole tower.This approach is worth adopting in future pole tower design work.
