Oil-Immersed Transformer

Oil-immersed transformers offer the following four core product features:
1. Excellent Heat Dissipation and Insulation Performance
Oil cooling: Insulating oil circulates inside the transformer to dissipate heat, providing much higher cooling efficiency than natural air cooling.
High insulation strength: The oil has high dielectric strength, effectively preventing internal high-voltage discharge and flashover.
2. Long Service Life with Sealed Design
Fully sealed structure: Prevents air and moisture from entering the transformer.
Slower oil aging: The insulating oil is less likely to oxidize, greatly extending the overall service life of the equipment.
3. Strong Weather Resistance and High Protection
Environmental resistance: Moisture-proof, dust-proof, and salt-spray resistant, making it highly suitable for humid or harsh outdoor environments.
Preferred for outdoor installation: Compared with dry-type transformers, oil-immersed transformers are more commonly installed directly in outdoor substation areas.
4. Short-Time Overload Capability with Larger Thermal Capacity
Due to the large amount of insulating oil absorbing heat, oil-immersed transformers can withstand sudden peak loads for a longer period of time.
