Transformer Oil I-10 Model
Transformer insulation oil is an electrical insulation oil mainly composed of base oil and additives. Base oil is the most important component in insulating oil, which determines the stability and heat resistance of insulating oil. Additives can improve the performance of insulating oil, such as enhancing antioxidant capacity, corrosion resistance, and reducing medium loss.
Product Details：Transformer Oil I-10 Model
This product has strong antioxidant properties and can effectively reduce the formation of oil sludge. Low viscosity for circulation, convection, and heat dissipation. The product has a low flow point and can maintain good fluidity in low temperature climates. High flash point to prevent ignition. Low volatility to avoid volatilization and loss. The oil color is light, so as to check the condition of the internal joints in the oil layer.
