Ventia is a key services partner to some of Australia’s largest electricity network owners. 

For our customers, having a partner that can deliver exceptional service, whilst also looking to continually improve through innovative solutions is a critical reason why they continue to choose us.  

Our energy networks team recently trialled the use of a state-of-the-art line puller for use on reconductoring projects. The use of this machine is an Australian first and has the potential to significantly improve how our team deliver these projects in the future.  

For energy network owners, transmission line maintenance is critical to ensuring reliable service for end users. 

A key element of any maintenance program is overhead line reconductoring, which involves replacing aging or underperforming power lines with new, higher-capacity conductors to improve the reliability and efficiency of the electricity transmission network. This process helps meet growing energy demands, supports renewable energy integration, and ensures a stable power supply across urban and regional areas.

Traditional methods of reconductoring, whilst effective, incorporate a number of steps and multiple pieces of equipment, adding time and complexity to the task. 

Utilising Australian first technology to improve delivery

In an Australian first, Ventia’s energy networks team in Adelaide, has trialled  an overhead line reconductoring using a continuous line puller (CLP). 

The CLP directly addresses the core challenges of traditional reconductoring with a fully integrated, four-in-one machine that:

• Maintains continuous pulling speed, even when joints pass through
• Reduces outage duration 
• Eliminates the need for equipotential zones (EPZs)
• Simplifies logistics with fewer trucks and no drum stands.

This innovation allows the team to operate in a safer, cleaner, and more efficient environment-while maintaining the integrity of the power network.

Prepping for Innovation

The use of the CLP has required significant pre work from the Ventia team, led by Operations Manager Keith Carew, the team has researched and trialled the CLP in order to ensure it was fit for purpose for the tasks required.

The team also spent time with their New Zealand colleagues who have utilised this type of technology across many projects, to manage reconductoring across some of the more challenging geographies they work across.
