Wood power poles switch to concrete
Motorists will have noticed that Scanpower is busy replacing hardwood poles.
These were installed in the Scanpower network up to the 1970s. From the 1980s onwards, lines companies switched to using concrete poles which have a longer service life of at least 60 years and are safer in numerous ways.
There are currently 900 hardwood poles in the network and Scanpower plans to have them all replaced within five years at a cost of $1 million per year. Already in April and May 48 poles have been replaced.
There is an annual timetable so that customers can be warned in advance. The timetable is determined by the condition of the poles.
Upcoming areas for clusters of pole changes include Range Rd, Bluff Rd, Harris Rd, Oxford Rd, River Rd, Weber Rd, Route 52, Totaramahonga Rd, and numerous urban poles in service lanes and the like.
In conjunction with this work, Scanpower is taking the opportunity to install additional switches on the network.
CEO Lee Bettles says, “This allows us to reduce the number of customers affected by an outage, whether that is planned or unplanned.”
Scanpower is continuing to win contracts beyond the Tararua. Lee says, “We were recently successful in securing power line relocation, street lighting and electrical contracts for the Peka Peka to Otaki Expressway project. Scanpower teams commenced work on site recently and will be initially deployed there for around three months. We will return to do the streetlights and other electrical work later next year.”
He adds: “Also of interest, this week a small team from Scanpower will be working in the Chatham Islands (a regular customer of ours) undertaking power line surveys, GPS location recording, and asset condition reporting. We anticipate that this will lead into further maintenance work over the in the coming years.”
