Oil-Immersed Transformers in Data Centers
As a key component of data center power supply, oil-immersed transformers play a vital role. Data centers place extremely high demands on the reliability and stability of their power supply. Oil-immersed transformers, with their excellent heat dissipation and high load capacity, effectively ensure power supply stability. Furthermore, their high reliability and ease of maintenance make them a popular choice for data center power supply equipment.

Advantages of Oil-Immersed Transformers in Data Centers
1. Excellent Heat Dissipation: Oil-immersed transformers are immersed in insulating oil, effectively transferring heat generated within the transformer to the outside, ensuring operation within a stable temperature range.
2. High Load Capacity: The design of oil-immersed transformers enables them to have a high load capacity, meeting the power demands of large-capacity equipment in data centers.
3. High Reliability: The enclosed design of oil-immersed transformers effectively protects insulation and cooling, thereby enhancing their reliability and stability in data centers.
4. Simple Maintenance: Oil-immersed transformers require relatively simple maintenance; regular oil replacement and insulation inspection are required to ensure proper operation.
