## About the brand

MIDEL is a brand of ester-based transformer insulating fluids developed by the UK company M&I Materials in Manchester, introduced in the 1970s as an early commercially applied synthetic-ester transformer liquid; it is now part of Shell's transformer fluid portfolio and marketed as Shell MIDEL. The range includes the synthetic ester fluid MIDEL 7131, the natural ester fluids MIDEL eN 1215 and eN 1204 formulated from renewable seed crops, and MIDEL Regen made from regenerated in-service fluid. With a high fire point, K-class fire performance and biodegradability, MIDEL fluids are used both in new transformers and as a retrofill for flammable mineral oil, in urban and indoor substations, rail networks, building distribution, and wind and solar installations.
