Design of Transmission Lines and Tower Structure at Different High Voltages to Transmit Power with Minimum Losses

When designing transmission lines, the basic data used in the design would be the power to be transmitted and the distance over which it is to be transmitted. After the transmission line designed to particular specifications, the construction and layout of the line start. Size of conductor, spacing of conductors, types of the poles or towers, span to be used, number of insulators per string, size of the ground wire, location of ground wire on towers, permissible tension in stringing the conductors, sags for different poles at equal or unequal height, grounding resistance, etc. In this paper, Analysis and Design of Transmission line considering multi voltage& multi circuit transmission of power has been carried out keeping in view to provide optimum electric supply and the efficient design of Tower Structure. The aim of this paper is to display the optimum design of the systems but because of the practical restrictions, this has been achieved through intuition, experience and repeated trials at different high voltages 132 Kv, 166Kv, 230Kv, maintaining the power loss and cost minimum.
