Modeling of Ice-Shedding from ACSR Power Line
Journal Title: Strojnicky casopis - Journal of Mechanical Engineering - Year 2017, Vol 67, Issue 1
Abstract
In this contribution, the analysis of ice-shedding from Aluminium Conductor Steel Reinforced (ACSR) power lines is presented. The impact of the icing position on the overhead power lines, the resulting jump height, and impact on attachment tension points after ice-shedding is examined. In the numerical simulations the effective material properties of the ACSR conductor is calculated using the homogenisation method. Numerical analysis of one power line and double-bundle power lines with icing over the whole range or only on certain sections of single and double-bundle power lines are performed.
