Our
transformer oil is produced by optimum refining of carefully selected Paraffine base oil and then for improvement of the electrical properties it is further processed by the newest dehydrating and deaerating facilities. So, it excels in flash point, pour point, oxidation stability and corrosion resistance etc. satisfying KS 2301, ASTM D3487, IEC-296, BS-148, JIS C-2320 etc. and receives recognition as top class products for various type of transformers. |
