An oil capacitor is a type of capacitor that uses oil as an insulating material. This oil provides insulation between the electrodes inside the capacitor and also serves as a coolant to efficiently dissipate heat. Oil capacitors are commonly used in high-voltage applications and play a crucial role in power systems and high-voltage electrical equipment.

Mechanism

An oil capacitor typically consists of metallic electrodes (cores) with insulating oil used as the dielectric material between them. The oil has high insulating properties, making it ideal for high-voltage environments where stable operation is essential. Additionally, the oil absorbs heat generated between the electrodes and the dielectric, helping to maintain stable performance by preventing excessive temperature rise.

Features

• High Voltage Compatibility: Oil capacitors can withstand very high voltages, making them ideal for use in power equipment and transmission systems.
• Cooling Function: The internal oil absorbs heat, cooling the capacitor and ensuring long-term stable performance.
• High Capacity: Compared to other types of capacitors, oil capacitors can store relatively large amounts of energy, making them efficient for energy storage and supply.
