Why is MIDEL transformer oil chosen for environmentally sensitive sites?

MIDEL branded fluids are commonly ester based insulating liquids selected when fire safety and environmental impact matter, such as urban, tunnel, or water proximity sites. Esters typically offer higher fire points and better biodegradability than mineral oil, helping reduce fire propagation risk and environmental remediation burden after a leak. Utilities still verify compatibility, moisture behavior, and aging performance against their standards and asset strategy.
