Abstract (en)
[origin: WO2005118756A1] Disclosed are compositions containing trimethylolpropane ester (TMP)-ester of general formula (I), wherein R1, R2, and R3 identically or differently represent a straight-chain or branched-chain alkyl group comprising 5 to 11 C atoms. The ester has a viscosity of less than 23 mm<2>/s at 40 DEG C and an ignition point > 300 DEG C. The inventive compositions are used as a dielectric insulating liquid for transformers.
