30 Innovative pole fixture device streamlining power pole repairs Power and Water is committed to providing a safe and reliable power supply and finding innovative ways to deliver power services for our customers. We have undertaken a program of power pole replacements in Alice Springs over several years. After flooding of the Todd River in 2015, during which a power pole was washed out and collapsed, a comprehensive inspection of all power poles took place. Initial investigations found the pole had corroded below ground due to soil salinity, and a further 900 poles were at increased risk of failure. Our team developed an innovative engineering solution known as a 'pole fixture'. The pole fixture is made of steel and concrete and weighs more than 10 tonnes. It stands approximately 2.5m high, 2m wide and 5m long. The fixture holds the pole in place with a large mechanical jaw while the corroded base is replaced. It is then left in place until the concrete footing sets. The pole fixture is the first of its kind in the utilities sector in Australia and has been patented by Power and Water. Our pole fixture device has streamlined our pole base replacement process. Ultimately the work can be done faster and safer, and without the need to interrupt the power supply to surrounding customers. We have repaired more than 700 poles using the pole fixture so far. When complete, this project will have saved more than $6 million in works. Pole repairs in Alice Springs. 700 poles repaired to date $6million in savings when complete
