Economical design for power transmission steel towers

경제적인 송배전철탑설계

The economical design of steel towers fortrausmission line. This study has been made on the design criteria of steel towers for power trasmission line adopted in the United States of America, France, Japan and Korea in order to find out any access to design the economical steel twers in Korea following to our own climate conditions. As the result of this study, involved in this description. Writer belive that the weight of steel towers can be saved by 10% to 20% approximately on the steel towers which will be constructed in the near future in Korea, by the possibility of reducing the design wind pressures on towers and cables in those areas of inland of Korea, the increase of number of standard towers from four types to five, the adoption of comparative narrower base towers than those in past practice and improvement on the assumption of manimum delection angle of suopension type insulator strings.
