Christian Lagasca is a current Zinfra apprentice transmission linesman, working
on high voltage power line and substation construction and maintenance projects.
Big power infrastructure is dotted across the Australian landscape, a symbol of our
achievements in energy creation and management as much as it features in Australian
politics and fast evolving issues of climate change, consistent energy supply and economic
creation. Transmission line work is constant, to maintain the huge numbers of towers and
powerlines and build the new infrastructure Australia needs as our population grows and
energy demand increases.
In Victoria alone, where Christian lives, there are over 13,000 transmission towers and
6,685km of high voltage transmission powerlines, with the electricity from power generators
being directed to and changing down to lower voltages for distribution through terminal
switching stations and substations to reach consumers. Zinfra is a trusted energy partner to
AusNet Services who own and maintain the transmission network in Victoria, recently
awarded the contract to manage the operations and maintenance in the North and East
regions with the North West region to be mobilised within the next few years. In addition,
Zinfra’s Projects and Construction division are frequently contracted to build new assets and
upgrade the existing infrastructure. Zinfra has transmission line specialists who work across
the country to ensure power is readily available to communities and industry every day.
For Zinfra’s apprentice line workers, each day offers new challenges in urban, regional and
remote landscapes working on transmission assets, where the view from close to 50m in the
air is nothing short of spectacular and is literally a charged experience!
For Christian, aged 33 years, a Zinfra apprenticeship has been the vehicle to upskill and
build on his trade as a licensed electrician, and grow his skills and experience in the
mechanical industry. He was also seeking the ability to work outside and work with a bigger
crew and within a bigger company that can provide career progression. Christian has been
based out of the Keysborough Depot and studies at Holmesglen TAFE to provide the formal
training aspects of his apprenticeship.
Christian outlined some of the exciting jobs he has worked on so far, since starting with
Zinfra in 2019. “During my time I’ve been shuffled around and exposed to numerous different
projects and environments in Victoria and SA which has been fascinating.”
This includes new connection assets for the Stockyard Hill Wind Farm, constructing a 132kV
powerline, clamping in conductors and the new substation at Haunted Gully out of Ballarat
which will transmit the power from the windfarm into the national electricity grid. Another
project has involved installing fibre optic ground-wire cabling onto towers in South Australia,
which provides data transmission and improved safety and communications.
used to string the cables with the lines team at height to manoeuvre lines into position atop
the transmission towers. Christian has also undertaken 500kV powerline insulator
changeovers, giving him a full perspective on transmission life. Currently he’s working on power connections for the West Gate Tunnel in Melbourne.
“It took a while to adjust to the changing routine. We work 21 days on and a week off most
projects so that can impact on home and family life but you also get a lot out of it and the
time spent with your crew. That also takes time to get used to but the rewards are great.”
We asked Christian what advice he would like to give incoming Zinfra apprentices and
“Take in as much as you can from your supervisors and your crew leaders.”
“Be open minded. Always ask questions when you need to.”
”Enjoy your time within this four-year apprenticeship and take advantage of where this job
“If you have any questions, any dramas, don’t hesitate to talk to your peers, your
supervisors, your crew leaders, your mentors and us also, the older apprentices – we’ll
reach out a lending hand to let you know we’re out here to help you as well in this journey.”
“I’ve come into this apprenticeship with the knowledge of my previous pathway, as an
electrician on big commercial and industrial facilities, furnaces and high-rise so I appreciate what this offers. I always say to the younger ones how good it is to be in this kind of
company, and this industry by comparison. It’s a great place to be”.
