Historically, conductors used on the system are Aluminium Conductors Steel Reinforced (ACSR) of Zebra (400mm2, 54/7, 28.62mm diameter) design, but with
different levels of grease protection, and past exposure to environmental
conditions that vary widely throughout GB. Other stresses (e.g. conductor
vibration due to subconductor oscillation) may also have a significant influence
on remnant life. This project is to determine the condition of conductors, both in
service and taken from service, assess the extent and form of any damage and
corrosion, and determine the likely remnant life of conductors.
To review the technical asset life for ACSR Conductors.
