    Abstract:
      Introduction  Exploring the difference of quantities between composite cross arm tower and conventional tower in different design schemes can quickly carry out scheme comparison and selection in the planning and design stage, and provide reference for the application of composite cross arm tower in different scenarios.
      Method  Taking the 500 kV tower as an example, the tower was divided into several parts, and compared with the design scheme of the composite cross arm tower. At the same time, the tower weight, the amount of foundation concrete, the quantities of fittings and insulators were calculated, and the differences between the quantities of each composite cross arm tower and the conventional tower were studied.
      Result  The calculation results show that compared with the conventional tower, the design scheme 1 of composite cross arm tower has better economy, better corridor compression performance and poor emergency repair performance; Design scheme 2 of composite cross arm tower has general economy, good corridor compression performance and general emergency repair performance; Design scheme 3 of composite cross arm tower has poor economy, good corridor compression performance and good emergency repair performance.
      Conclusion  The research results of this paper can provide reference for the selection of composite cross arm scheme in the future.
