Murra Warra Wind Farm Stage 2

Overview

The Murra Warra II Wind Farm in Victoria is a 209 MW project featuring 38 turbines, generating 809 GWh annually—enough to power over 175,000 homes and avoid 640,000 tonnes of carbon emissions each year. To support its high-voltage infrastructure, Insulect supplied 33kV Disconnectors and 33kV Rocker Switches, ensuring reliable and safe energy distribution across the network.

Challenge

Wind farms like Murra Warra II don’t produce a constant flow of energy, the output changes with the wind. This means the electrical network needs to be flexible and dependable at the same time.

The site is also spread out across a large area, with many turbines feeding into one network. Operators need to be able to isolate sections for maintenance or deal with faults quickly, without affecting the whole system.

On top of that, all equipment has to handle outdoor conditions and keep working reliably over the long term.

Solution

Insulect supplied 33kV disconnectors and 33kV rocker switches designed for this kind of environment.

The disconnectors allow parts of the network to be safely switched off when needed, so maintenance can be carried out without risk. The rocker switches support smooth and reliable operation of the system, helping control how power moves through the network.

Together, these components were installed as part of the wind farm’s electrical infrastructure, built to handle changing conditions and day-to-day operation.

Benefits

With Insulect’s equipment in place, the wind farm has a safer and more flexible electrical system. Teams can isolate sections easily, which makes maintenance safer and helps reduce downtime.

The equipment is designed to be reliable, even in tough outdoor conditions, so the system can keep running smoothly over time.

This also helps ensure that energy generated by the turbines is delivered consistently to the grid, even when wind conditions change.

Results

Today, Murra Warra II is delivering clean energy to thousands of homes across Victoria, helping reduce the state’s carbon footprint.

Behind the scenes, its electrical network works reliably to keep power moving from the turbines to the grid.
