Review on Application of Utility Poles for Power Transmission

Abstract

Power transmission is generally carried out using transmission poles of various materials and cross sections. However, their utilization depends on climatic conditions and external loads acting on them. For an electric overhead system, the supports for the conductor and equipment must withstand the forces imposed on them, while the conductors themselves must be sufficiently strong enough to support their own weight and the forces imposed on them. The forces comprise of wind pressure and tension in conductors. This paper presents the various researches conducted on the various aspects of utility poles in which their strength and service life are estimated; and the suggestions in methodologies for the assessment of various properties of utility poles.
