Objectives: To design multi-voltage multi-circuit transmission tower to reduce right of way (RoW). Methods/Statistical Analysis: In order to reduce right of way structural optimization and electro-magnetic analysis should be carried out. Structural optimization includes various factors like conductor configuration, cross arm arrangement, wind loadings. The tower is designed using Staad Pro and the structure is validated for various wind loadings and stresses. Electro-static and magneto-static fields around the tower are analyzed and are brought down to limits by choosing optimal phase sequence. This analysis is carried out using Ansoft Maxwell. Findings: The designed structure withstands all the permissible stresses. Electro-static and magneto-static fields around the designed tower are found to be within the specified limits specified by standards. This design is found to be cost effective with respect to right of way when a transmission line is considered. Application / Improvements: Narrow base width is considered which also aids in optimized right of way. This tower design can hold three voltages (400kV, 220kV, 33kV) and six circuits. The height of the tower is maintained in normal range by structural optimization.
