After positive feedback and high demand, we are excited to announce that we will be running a second Overhead Line Design (OHLD) online seminar series in February!

Like the seminars we ran last September, this course is perfect for those who want to up-skill their OHL design, are keen to find practical solutions to some of the issues faced in the industry or are wanting to get a refresher on OHL design efficiency.

With a focus on practical outcomes and producing an environment for quality learning, we have decided to extend the seminar to hosting the 4 sessions over the span of 2 weeks, with each session going for 2 hours.

This seminar series will be live on Wednesday 16/02, Friday 18/02, Wednesday 23/02, and Friday 25/02. They will start at 11am AEDT (11am NSW/VIC/TAS/ACT, 10am QLD, 9:30am SA/NT, 8am WA).

These seminars will be recorded and available to watch on replay. Our goal with this training course is for trainees to be able to:


  • Identify what information they need to collect as inputs to a line design.
  • Analyse a range of line design solutions and identify the optimum (robust) solution to meet the needs of the client.
  • Document the design details into a construction package.

More about the February OHLD seminars.

This 4-session online seminar series has been developed to help those in the industry as overhead lines play a pivotal role in Australia infrastructure. Without strong OHLD, issues arise delivering energy around the nation. As overhead line assets age and reliance on the grid increases, line design is more important than ever before.

These seminars are aimed at covering some of the electrical and structural aspects of detailed overhead line design. These seminars have been developed after years of observing and noting gaps in knowledge within the OHLD industry and have been further tailored by the feedback from the first seminar series.

Check out the review below to find out what you can expect:

I just wanted to thank you for running the series of OH Line Design Seminars and for extending the invitation to my team and I to attend. I found the sessions really informative and presented in such a way that even someone with a limited knowledge of overhead line equipment and design principles would understand the content.

The format and approach taken by Grant and Nathan in aiming this training for learning and professional development will be really popular within an organisation like ours, given our geographic spread of employees. Please let us know about any future similar events and I will be sure to promote them across the organisation.


Network Management

With a focus on helping the industry becoming more unified and more informed, we will also provide a time for Q&A at the end of each session and a pdf with all the presented material included.

This is the introduction to the full in-person course that would normally take 3 full days and include a lot more detail, topics, field excursions, worked examples and quizzes. And it will come with a price to suit all this extra content. This four-day seminar series is only $198 per person including GST, an absolute bargain.

Who should attend?

These seminars have been created for OHL designers of any and all skill levels, with a particular focus on helping those who are relatively new to the design space. There will be a space for Q&A that will be great for technical discussions in each session.

How to sign up for the course.
