Abstract
Degradation and breakage of Aluminium Clad Steel Reinforced (ACSR) conductors leads to power outages that have catastrophic impact from an economic, social and national security point of view. Frictions, vibrations, corrosion, as well as other chemical compounds from the environment, can be the main source of the damages. Environment provides much of the time less restrictive conditions than those designed in the standards. In this respect, issues of optimization and development of current diagnostics and forecasting techniques personalized on geographic areas arise.

Degradation and breakage of Aluminium Clad Steel Reinforced (ACSR) conductors leads to power outages that have catastrophic impact from an economic, social and national security point of view
Frictions and vibrations created by the wind, corrosion caused by industrial pollution as well as other chemical compounds from the environment can be accounted as the main source of the damages
The estimation of the lifetime of conductors exposed to current environmental conditions across Timisoara - Arad is possible applying the method average annual loss of torsional ductility vs. environmental corrosion index used by Havard D.G. [9] and the mechanical tests results acquired by Achiriloaiei D. [8]
Summary
Degradation and breakage of Aluminium Clad Steel Reinforced (ACSR) conductors leads to power outages that have catastrophic impact from an economic, social and national security point of view. G. Chen et al [1] presents the results of special tests performed on the wires of a steel-aluminum conductor which was in operation for 25 years.
