Distribution Transformers 3.3-33 kV

Hunter Transformers supply Medium Voltage (MV) Distribution Transformers that provide reliable and efficient voltage transformation for a wide range of applications. From urban and rural networks to renewable energy projects, industrial facilities, and commercial developments, our transformers are engineered to ensure stable, safe and consistent power delivery to end-users.

Our distribution range covers oil-immersed (ONAN or KNAN) and dry-type (AN) transformers, configured to meet project-specific requirements. Each unit is built with a strong focus on energy efficiency, durability and low maintenance, ensuring long service life and reduced operational costs. With advanced insulation, cooling systems, and protection options, our transformers withstand demanding environmental and load conditions.

Hunter Transformers also offer custom-engineered distribution transformer solutions, tailored to unique operational and compliance needs. Typical primary voltages include 3.3kV, 6.6kV, 11kV, 22kV & 33kV.

Whether supplying equipment for large-scale utilities, renewable energy farms or commercial sites, we work closely with clients to deliver transformers that integrate seamlessly with existing infrastructure and meet relevant Australian and international standards.

By combining decades of manufacturing expertise with strict quality control and testing processes, we provide distribution transformers that support network reliability, operational safety and long-term energy efficiency.
