A product of M&I Materials, MIDEL is the world’s
leading brand of ester-based dielectric fluids.
MIDEL is chosen by utilities and transformer
manufacturers because of its excellent
performance track record and ability to minimise
risk. Our synthetic ester MIDEL 7131, and natural
esters MIDEL eN 1204 (rapeseed) and MIDEL eN
1215 (soybean), provide superior fire safety and
greater environmental protection than conventional
dielectric fluids. They also deliver exceptional
moisture tolerance which increases protection of
cellulose insulation and potentially extends
transformer life
