Abstract
Technology is proposed for production of transformer oil with improved performance characteristics based on a narrow oil cut of medium-sulfur paraffin-base crude by selective treatment with N-methylpyrrolidone and final treatment with an adsorbent in fixed conditions. The oil obtained is distinguished by high stability of the electrical characteristics.
