MIDEL ® SAFETY INSIDE SYNTHETIC AND NATURAL ESTER TRANSFORMER FLUIDS The MIDEL family of ester transformer fluids - delivering fire safety and environmental protection to India’s power sector. MIDEL 7131 MIDEL eN 1204 MIDEL eN 1215 The world-leading fire safe, biodegradable, synthetic organic transformer fluid, MIDEL 7131 has exceptionally high moisture tolerance, enabling it to extend cellulose insulation life. It is used in a wide range of transformers up to 433kV. Perfectly suited for non-breathing and free-breathing transformers (due to its excellent oxidation stability), MIDEL 7131 offers the ability to safely increase transformer loading or reduce transformer size. MIDEL eN 1204 is a natural ester liquid (rapeseed) with a high fire point that significantly increases fire safety and reduces the need for fire protection equipment. It is sustainably sourced and readily biodegradable, enabling reductions in containment measures. MIDEL eN 1204 has a pour point around 13°C lower than the soya-based natural ester, making it ideal for cooler climates. MIDEL eN 1215 is an excellent dielectric fluid because it has a high fire point, making it demonstrably safer than mineral oil. Environmentally friendly, MIDEL eN 1215 is made from renewable vegetable oil (soya), and is also non-toxic and readily biodegradable. In addition, MIDEL eN 1215 offers superior moisture tolerance and has the potential to increase the lifetime of cellulose based solid insulation, which in turn can extend transformer life.
