In order to promote the application of glass fiber reinforced polymer（GFRP） in UHV project

taking the Ximeng-to-Shengli UHV project as an example

we proposed the electrical and structural design schemes of GFRP cross arm suspension tower

and made the finite element analysis of electric field and structure. Then we carried out and passed the electrical verification test

the full-scale tower test

and the tension-compression fatigue test. Finally

we put forward an engineering construction and acceptance scheme

and the operational plan of GFRP cross arm suspension tower. Through economic comparison of the conventional steel tower

the height of proposed tower standard is reduced by 8 meters

the corridor width is reduced by 21.2 meters

and the project cost is reduced by 4%.
