Vegetable Oil Transformer Cooling Solutions
Typically, insulating oil has three key roles: providing insulation, facilitating heat dissipation, and extinguishing arcs. The operational reliability of electrical equipment, including transformers, reactors, and oil switches, significantly depends on these essential characteristics of the insulating oil. In transformers, reactors, and inductors, the oil mainly contributes to insulation and cooling. Furthermore, if an arc is generated in these devices, the oil also functions to extinguish it. In oilfilled casings, the oil primarily serves as insulation, whereas in oil switches, it is vital for both arc extinction and insulation.
Product Details：Vegetable Oil Transformer Cooling Solutions
Known interchangeably as liquid insulating material or insulating liquid, insulating oil functions as a liquid barrier separating conductors with different voltage levels. It fills gaps within or between solid poles, thereby enhancing their dielectric capabilities and facilitating better heat dissipation within electrical devices. As a fundamental insulating component, proficient handling and maintenance of insulating oil are vital for maintaining the smooth operation and safety of electrical systems.

1. Applicable Industry
High-voltage transformers: The role of transformer oil is vital as it acts as an insulating medium to prevent arcing and short circuits, while also providing effective insulation protection at elevated voltages.
Distribution transformers: In low-voltage distribution systems, transformer oil aids in heat management, ensuring that equipment remains within safe operating temperatures and contributing to a reliable power supply.
Generators: Transformer oils are utilized for both insulation and cooling in generators, which helps lower internal temperatures and boosts efficiency and longevity of the machinery.
Steam Turbines: Transformer oil is essential in the electrical systems of steam turbines, offering insulation that guarantees safe equipment operation even at high temperatures and pressures.
2. Environmental Friendliness of Transformer Oil
Biodegradability: Conventional transformer oils, which are mainly petroleum-based, have a poor capacity for biodegradation. They can persist in the environment for decades, causing lasting harm to soil and water quality. On the other hand, modern vegetable-based transformer oils, including soybean and canola oils, are very biodegradable, often breaking down within just a few months. Furthermore, synthetic oils, such as esters, are environmentally friendly and can also decompose relatively quickly in natural settings.
