What is the remaining life of your transmission lines and can it be extended?
Do your structures and foundations require refurbishment or upgrading?
Can your structures support larger size conductors or an additional circuit?
A critical decision
Electrical utilities face critical, ongoing decisions about the management, service life extension and refurbishment of their transmission lines.
