Used in industrial and commercial applications, oil-immersed transformers have fuelled the growth in the efficiency of power distribution systems. These specific transformers submerge their core and windings in insulating oil which preforms three essential tasks simultaneously: cooling, providing proper insulation and guarding against moisture. The oil alleviates overheating by absorbing heat, while insulating against electrical breakdowns. Additionally, it guards the internal parts from moisture, ensuring reliable and durable performance.
Types of Oil-immersed Transformers
Distribution Transformers – Compact units that deliver electricity to localized networks such as residential and commercial areas.
Power Transformers – Designed for high-voltage applications, commonly used in power plants and substations.
Conservator-Type Transformers – Equipped with a conservator tank to manage oil expansion and contraction under fluctuating loads.
Hermetically Sealed Transformers – Completely enclosed to prevent contamination, reducing risks of leaks and degradation.
Key Benefits
Withstand the test of time – Used oil-immersed transformers suffered proper maintenance, they can efficient operate for several decades.
Reliability & Longevity – The cost-effective nature of these transformers stems from their initial price being lower than dry-type transformers alongside long-term energy efficiency benefits.
High voltage capabilities – Excellent cooling efficiency through oil ensures high-load applications can be performed with ease.
Superior cooling efficiency – Oil ensures optimal dispersal of heat, aiding in optimal transformer function.
“An oil-immersed transformer is widely regarded as a preferred option due to its ability to distribute high levels of electrical power seamlessly and efficiently in industrial applications. They provide transformers with their distinct oil-filled characteristics which makes them highly sought after in electrical infrastructure.
