✔ Transformer Tank

In oil-immersed distribution transformers, the transformer tank is typically designed as a hermetically sealed or conservator-type structure, filled with insulating oil to provide both dielectric insulation and heat transfer.

Key features include:

• Compact and space-saving design
• Excellent sealing performance to prevent oil leakage
• Strong resistance to outdoor environmental conditions
• Integrated corrugated walls in many designs

The tank ensures safe operation in urban and rural power distribution networks, where reliability and low maintenance are essential.

✔ Radiator

For this type, radiators are usually:

• Corrugated tank fins (integrated cooling walls), or
• Small detachable radiators

Cooling method:

• Primarily ONAN (Oil Natural Air Natural)

Advantages:

• Maintenance-free operation
• Low cost and high efficiency
• Suitable for continuous operation with moderate load
