Key Industry Partner: MIDEL Service Partner

MIDEL manufacture natural and synthetic ester transformer fluids. PBA are a MIDEL Service Partner and are agents for the supply of MIDEL ester transformer fluids.

The MIDEL range of ester transformer fluids delivers an array of distinct benefits when used in a power transformer or distribution unit. Because they offer three different ester fluids, their customers can choose the one that best suits their specific installation and performance criteria. All three MIDEL fluids are more fire-safe and eco-friendly than conventional transformer oil. 

MIDEL eN 1204, MIDEL eN 1215 and MIDEL 7131 are all suitable for use in power transformer applications up to 400kV. The fluids all offer the benefits of being readily biodegradable (avoiding environmental damage should leakage occur) and enabling reductions in containment measures. MIDEL 7131 is perfectly suited for non-breathing and breathing transformers (due to its excellent oxidation stability) located indoors or outside.

MIDEL's natural ester fluids MIDEL eN 1204 (rapeseed) and MIDEL eN 1215 (soya) are produced from renewable vegetable oils, providing an effective, environmentally friendly solution for non free-breathing power transformers. MIDEL eN 1204 (rapeseed), with its pour point of -31°C, is better suited to colder installation climates than soy-based natural ester fluids.
