Study on Pitch Diameter Ratio Optimization of Transmission Line Basised on Genetic Algorithm

The mathematical model of relation betwteen pitch diameter and stress of the wire has been builded by analysing stress distribution among layers of transmission line, genetic algorithm has been used to optimize the wire pitch diameter ratio. The optimization results show that: when the pitch diameter of the wire be equaled to the upper limit, the contact stress between the layers reaches a minimum. Research findings can provide a certain theoretical basis on the desigen of the wire, antifriction, reduce line losses and an extension of lifetime, it has a higher value in engineering
