Product Description

Description about Hermetically-sealed Oil immersed transformer
A hermetically-sealed transformer is a type of oil-immersed transformer designed to be completely sealed to prevent the ingress of moisture and air. This design enhances the transformer's reliability and reduces maintenance requirements. Here is an overview of hermetically-sealed transformers, including their characteristics, benefits, and applications:
Characteristics

1. Sealed Design: The transformer tank is fully sealed, preventing the entry of air and moisture, which can degrade the insulating oil and internal components.
2. Oil Preservation: The sealed environment protects the insulating oil from contamination and oxidation, ensuring its long-term effectiveness.
3. Maintenance-Free: Hermetically-sealed transformers require minimal maintenance since the oil and internal components are not exposed to external elements.
4. Temperature Management: These transformers often include a flexible tank design or gas cushion to accommodate oil expansion and contraction due to temperature changes without compromising the seal.
5. Corrosion Resistance: The sealed tank is typically made of corrosion-resistant materials, ensuring durability even in harsh environments.
