Analysis of Sag Caused by Stresses on Electrical Transmission Lines

The majority of design failures are attributed to a confluence of different stresses operating on the material both internally and outside. If the stress levels are controlled within the system's design parameters, early failure won't happen. The longevity of the material can be significantly shortened and failure may occur if the sum of the stresses exceeds the design capacity. The stress value utilized in the design of a structure or machine should be significantly less than the material's tensile strength to account for subpar material workmanship and potential overloading. Research has been done on improving the mechanical, electrical, and thermal properties of materials by reinforcing them with nano- or micro-particles. The stresses associated with overhead transmission lines are reviewed in this work in order to provide design and manufacturing guidelines for overhead power line conductors. It takes into account the pressures on the conductors as well as the forces that cause such stresses
