What are the benefits of oil-immersed transformers？
High-Efficiency Heat Dissipation: Oil-immersed transformers use insulating oil as the cooling medium. The thermal conductivity of the oil is much higher than that of air, enabling it to more effectively transfer the heat inside the transformer to the outer surface of the oil tank and then dissipate it into the air through natural convection or forced cooling methods.
Uniform Cooling: The oil can evenly cover the iron core and windings, ensuring a more uniform temperature distribution in each part and reducing the risk of local overheating.
High Insulation Strength: Insulating oil has excellent insulation properties and can provide a higher insulation strength than air, effectively preventing corona discharge and breakdown phenomena and enhancing the operational safety of the transformer.
Extended Lifespan: Good insulation performance can reduce the damage to insulation materials caused by electric field stress, thus prolonging the service life of the transformer.
Stable Operation: Oil-immersed transformers can still operate stably under high-temperature, high-humidity, and harsh environmental conditions, making them suitable for various industrial and commercial application scenarios.
Multiple Protections: Modern oil-immersed transformers are equipped with multiple protective measures, such as gas relays, pressure release valves, and temperature sensors, which can detect and handle abnormal situations in a timely manner to improve safety.
Suitable for High Power: Oil-immersed transformers are suitable for application scenarios with large capacity and high voltage, such as main transformers in power systems and power supply for large industrial equipment.High Efficiency: High-quality winding materials and advanced manufacturing processes make oil-immersed transformers highly efficient, with low losses, energy-saving, and environmentally friendly.
