Insulating Oil For Transformers I-30
I-30 transformer oil can effectively prevent discharge phenomena and power losses under high-voltage electric fields, meeting stringent insulation performance requirements. With lower viscosity and good low-temperature performance, it provides effective cooling and heat transfer, low-temperature start-up performance, and filtration performance. It also exhibits good solubility, capable of dissolving sludge formed during the operation of electrical equipment to avoid damaging insulation materials and affecting heat transfer.
Product Details：Insulating Oil For Transformers I-30
I-30 transformer oil is formulated by blending moderately refined, low pour point, and low sulfur content cycloalkyl base oil with high-quality antioxidant additives, featuring fast heat transfer, good oxidative stability, and excellent electrical performance. The product has stable and reliable performance, produced under strict quality control procedures with fixed product resources.
