What are the specifications for transformer oil coolers?

Transformer oil coolers are designed to maintain optimal operating temperatures for power transformers. Specifications typically include a heat exchange capacity measured in kilowatts (kW), material construction (often carbon steel or stainless steel), and a flow rate that matches the transformer’s cooling requirements. Additionally, they should have a pressure rating suitable for the operating conditions, and be compatible with the transformer oil type. Efficiency and maintenance accessibility are also critical factors in their design.
