Ester Fluids

Insulect provides Australian utilities and energy providers with world-class Ester Fluids backed by deep industry expertise, local support, and future-ready technology.

Enhanced Fire Safety Ester fluids have fire points above 300°C, meaning they are classified as K‑class less‑flammable fluids and greatly reduce the risk of pool fires. This reduction in fire risk can also lower the need for costly fire‑mitigation measures.  
Improved Transformer
Life & Performance
Ester fluids slow the ageing of cellulose insulation and safely absorb more moisture without reducing breakdown voltage. This helps extend transformer service life and provides more flexibility in managing load and operating temperatures.  
Reduced Environmental Impact

Natural and synthetic ester fluids are biodegradable and more tolerant of moisture than mineral oil. Their use can lower spill remediation costs and support compliance with environmental policies across sensitive or urban sites.
