[0062] Example 1 - Mixing HEAR Oil with Scalinate (95%-5% by weight)
[0063] Refined HEAR oil was mixed with refined glycerin in a 95:5 ratio by weight of HEAR oil to glycerin.
[0064] Then antioxidants and metal ion scavengers ETHANOX 4702, KEMIN BF320 and IRGAMET 30 were added at a temperature of 70-80° C. with stirring at concentrations of 3000 ppm, 500 ppm and 50 ppm, respectively.
[0065] The oil was then stored at a temperature of about 70°C under a vacuum of about -30 mmHg (-4 kPa) for at least 12 hours before being tested. The test results are shown in Table 1 below.

Abstract
The present invention relates to a composition suitable for use in electrical equipment containing a dielectric fluid including an oil component, the oil component including one or both of crambe oil and high erucic acid rapeseed oil and one or both of esterified crambe oil and esterified high erucic acid rapeseed oil.
Description
technical field [0001] The present invention relates to electrical equipment comprising a dielectric oil having a high erucic acid content. Background technique [0002] Dielectric (or insulating) fluids used in electrical distribution and power equipment, including transformers, switchgear, and cables, perform two important functions. These fluids act as electrical insulating media, ie have dielectric strength, and they transport the heat generated by the device away, ie serve as cooling media. When used in a transformer, for example, the dielectric fluid transfers heat from the windings and cores of the transformer or connected electrical circuits to cooling surfaces. In addition to having dielectric strength and cooling capabilities, ideal dielectric fluids for electrical equipment have little or no adverse impact on the environment, are compatible with the materials used to construct the equipment, and are relatively non-flammable. [0003] Mineral oils, derived from c...
