PLC SUPERTRANS is a high-quality electrical insulating oil, refined from premium mineral base oil through solvent and hydrogenation processes, then dehydrated and degassed under vacuum pressure to remove moisture and enhance dielectric properties. The product is nitrogen-treated to inhibit oxidation and contains antioxidant additives, delivering excellent cooling, insulating, and oxidation stability performance.

Sinopec Insulated Transformer Oil is a series of products blended using highly refined mineral oil and a selected antioxidant. It is designed for insulating and cooling transformers, oil-immersed switch-gear, and other electrical insulating applications. There are four grades, I-0℃, I-10℃, I-30℃, and I-40℃, which are selected based on their low-temperature performance. None of the grades contain harmful polychlorinated biphenyls (PCBs).
