Synthetic Ester Transformer Fluids
Synthetic Ester Transformer Fluid for High Performance Power Systems
MIDEL 7131 is a synthetic ester transformer fluid engineered to meet the demanding needs of critical, high-voltage power transformers—up to 433 kV and beyond. Known for its exceptional oxidation stability, fire safety, and biodegradability, MIDEL 7131 is trusted by utilities and OEMs for both new builds and retrofitting in environments requiring enhanced operational safety, performance, and sustainability.
Features & Functionality
With a fire point above 300°C, MIDEL 7131 dramatically reduces the risk of transformer fires compared to mineral oils. This enhanced safety profile makes it ideal for use in densely populated, high-risk, or indoor environments where fire prevention is paramount.
MIDEL 7131’s exceptional oxidation stability makes it highly suited to sealed transformer systems. It resists degradation over time, supporting extended service intervals and reducing the need for maintenance — even under high thermal loads.
Readily biodegradable and non-toxic, MIDEL 7131 supports sustainability goals and simplifies environmental compliance. In the event of a leak, its impact on surrounding ecosystems is minimal, making it an ideal choice for environmentally sensitive sites.
Approved for use at high voltage levels, MIDEL 7131 is widely used in retrofilling existing transformers. It is compatible with standard transformer materials and designs, allowing operators to upgrade performance and safety without full equipment replacement.
