FAQ
Q: Why is the oil-filled design critical for distribution transformers?
A: Oil filled distribution transformers use oil to cool windings efficiently, preventing overheating. This ensures stable power output under heavy loads while minimizing maintenance needs.
Q: What makes the oil immersed type transformer energy-efficient?
A: Our oil immersed type transformer combines high-grade silicon steel cores with optimized windings, reducing both no-load and load losses by up to 30%. This lowers operational costs over time.
Q: How does a three-phase oil immersed transformer benefit industrial projects?
A: The three phase oil immersed transformer supports balanced power distribution for large-scale equipment, ensuring consistent performance in factories or power substations.
Q: What is the difference between an "immersed transformer" and a standard dry-type transformer?
A: An immersed transformer uses oil for insulation and cooling, making it safer for high-voltage applications. Dry types lack oil but may require forced cooling, making them less efficient in harsh conditions.
