High-level power transmission
At Ampcontrol, we take a solutions-based approach to our transformers. Utilising our engineering smarts and advanced manufacturing capabilities, we create custom oil and dry type transformers that can facilitate high, medium and low voltage power supplies for electrical distribution substations, power generation, voltage regulation, mining, traction and refining applications as well as retrofits and OEM replacement.
Our transformers can be integrated with our fixed modular, relocatable and transportable substations, switchrooms and switchyards, as well as third-party products, to establish complete and comprehensive systems that meet complex energy needs.
We’re also highly proficient in the custom design and manufacture of transformers using alternative cooling fluids, including ester dielectric, for service levels up to 132kV.

Ester Fluid Transformers
Ampcontrol also offers ester fluid options for particular transformers to enhance performance and life expectancy.
Formulated from edible seed oils and food-grade additives, ester dialectic fluid is bio-based, sustainable, renewable, and recyclable and can support longevity within the operational life of transformers.
Our ester fluid transformers are ideal for environmentally sensitive locations, with the fluids quickly and thoroughly biodegrading in the event of an oil release.
Ester dialectic fluid is entirely compatible with standard transformer insulating materials components and with fluid processing equipment and procedures, and has a high flash point of 330°C, providing a high level of fire safety.
Some of the key benefits include:
- Biodegradable
- High flash point of 330°C
- Enhanced insulation performance and life expectancy
- Aging resistivity
- Available in transformers up to 132kV
- Offering natural and synthetic oils
- Reduced environmental footprint
