Abstract
A dielectric high purity vegetable oil—free from antioxidants and/or external additives to be used in electric equipment such as transformers, as isolating element and as cooling means and a method for obtaining the same in which the dielectric high purity vegetable oil—is obtained by means of the optimization of the bleaching steps—and deodorizing—from the Refining process—known as Modified Caustic Refining Long-Mix (RBD).
Claims13
A dielectric high purity vegetable oil, comprising:
- from 17.7% to 28.5% by weight of mono-unsaturated fatty acid;
- from 49.8% to 57.1% by weight of di-unsaturated fatty acid;
- from 5.5% to 9.5% by weight of tri-unsaturated fatty acid;
- and
- from 12.7% to 18.7% by weight of saturated fatty acid;
