Structural Design and Application of 110 kV Composite Insulating Crossarm
In order to promote the application of composite insulating crossarm in transmission lines,a design method of composite insulating crossarm for 110 kV transmission lines is proposed in this paper.The structural design is carried out based on the load calculation of strong wind,icing,installation and line breaking.The mechanical model of two-pull and two-pressure is established by finite element software,and mechanical calculation of the crossarm is carried out under four loading conditions of strong wind,icing,installation and line breaking.Stability and safety of the composite insulating crossarm are verified by actual tests.The composite insulating crossarm designed by this method meets safety require-ments and has been successfully applied to many 110 kV transmission lines.In view of the problems of large workload and long production cycle in the design of different line towers,it is the trend of future development to carry out typical design work.
