Frequently Asked Questions
What is a fully sealed oil-immersed transformer?
It is a transformer where the oil is completely isolated from the outside atmosphere. The corrugated tank expands and contracts to accommodate oil volume changes, preventing moisture and oxygen from entering.
What are the main applications for these transformers?
They are widely used in power plants, electrical substations, industrial mining sites, and petrochemical enterprises due to their robust performance in harsh outdoor environments.
What are the benefits of using a corrugated tank?
Corrugated tanks provide excellent heat dissipation and act as an expansion vessel, eliminating the need for an oil conservator and reducing the overall footprint and maintenance requirements.
How is the product protected during shipping?
We typically use high-quality wooden box packaging to ensure the transformer is shielded from physical damage and environmental factors during transit.
Does the transformer comply with international standards?
Yes, our products are manufactured according to strict quality guidelines and come with relevant certifications ensuring safety, efficiency, and environmental compliance.
Are the technical parameters fixed?
While the data table provides standard technical parameters, please note that specifications are subject to change based on specific delivery requirements and product updates.
