The pole design and study of EHV partially prestressed reactive powder concrete
Through analyzing ordinary concrete poles deficiency in practical applications,and the main factors,design process of EHV partially prestressed reactive powder concrete pole is studied.The current design method is introduced and.compared with the EHV prestressed poles.Results reveal that such poles have good crack resistance and high corrosion resistance,and can adapt to adverse atmospheric environment,especially for cold northern areas and the south high-saltregion,and could be used in the current 500kV EHV transmission lines.Hence,the poles may bring a significant economic effect and social benefits.
