UEA Electrical Completes SWER Line Renewal

Posted 28 March 2014

UEA has successfully delivered a major project in mid-western NSW for a Western Sydney supply authority. The project involved renewal of an aged single-wire earth return line (SWER).

Augmentation of seven kilometres of aged and rusty steel infrastructure was completed using Aluminium-Conductor Steel Reinforced (ACSR) and the installation of All Aluminium Alloy Conductor (AAAC).

ACSR was chosen for its benefits in extending over long distances without support. This was important as the project included connecting a number of spans greater than 250 metres in length. AAAC was used for its corrosion-resistance and anti-sag qualities, made possible by its strength to weight ratio.

As well as renewing the electrical line, 24 decayed timber power poles were removed and replaced with concrete posts.

Rough terrain and a remote location were expected challenges of this electricity infrastructure project, but ongoing wet weather created additional demands on its execution. However, all three issues were overcome with effective management by UEA’s experienced staff and the help of its professional sub-contractor crews.

The SWER line renewal was completed ahead of schedule and under budget.
