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.
