Midel transformer fluid was developed in 1978 as part of the research activities within GEC PLC. Originally a subsidiary of GEC, M&I Materials Ltd became independent in 1993. MIDEL 7131 is manufactured and sold by M&I Materials in Manchester in the UK and we provide worldwide service through a network of partners and agents.

Collaborations with Universities including the Schering - Institute of Electric Power Systems in Hanover have helped develop the applications of Midel. M&I Materials are members of the Cigré UK National Committee; Cigré is the International Council on Large Electric Systems. For more information please follow this link www.cigre-uk.org
