Natural Ester Transformer Oil For Transformers U-10
Transformer oil exhibits remarkable thermal stability, significantly reducing the internal temperature of equipment during long-term operation, thus preserving its operational integrity. During extended use, electrical equipment generates substantial internal heat. Transformer oil, acting as a coolant, efficiently circulates to dissipate this heat through the radiator, enabling the equipment to maintain its optimal operating temperature.

Prevent corrosion and oxidation: This oil can also protect metal surfaces from corrosion and prevent oil from reacting with other materials and forming harmful substances. In addition, it can also prevent oil from oxidizing at high temperatures and losing its insulation performance and stability.

Classification: Transformer oil
Executive Standard: GB 2536-2011 U-10 ℃ (general).
Application Scope: U-10 transformer oil is suitable for transformers and electrical equipment with similar requirements that users require oil without antioxidants.
Performance requirements for transformer insulation oil：
1.Flash point and self ignition point: Flash point refers to the lowest temperature at which insulating oil can burn under certain conditions, while self ignition point refers to the lowest temperature at which insulating oil can self burn under certain conditions. The higher the flash point and self ignition point, the higher the safety of the insulating oil.
2. Corrosion resistance: Corrosion resistance refers to the ability of insulating oil to corrode the internal metal components of transformers. The better the corrosion resistance, the longer the service life of the transformer.
