3. Vegetable oils
Vegetable oils were among the first insulating liquids used in the manufacture of electrical appliances (see F.M. Clark's general work in bibliography). They are essentially made up of triglycerides, i.e. triglycerol esters of fatty acids.
Their chemical formula is :
Fatty acids can be saturated (without double bonds) or unsaturated (with 1 to 6 double bonds)....
