FAQ
 

Q1: Why should I choose an oil immersed transformer over other types?

A: Oil immersed transformers (OIT) excel in high-voltage applications due to their oil immersed transformer design, which ensures superior insulation and heat dissipation. This reduces energy losses, improves efficiency, and guarantees safety in industrial environments.

Q2: What voltage ranges do oil immersed transformers typically handle?

A: The oil immersed transformers in our S11-20 Series support 6–10kV (high-voltage side) and 0.4kV (low-voltage side). These are ideal for industrial facilities requiring stable power distribution across medium-to-high-voltage systems.

Q3: How does an oil immersed power transformer ensure reliability in harsh environments?

A: The oil immersed power transformer uses a hermetically sealed tank and epoxy-resin insulated terminals, protecting against moisture and contaminants. This extends lifespan and maintains performance in extreme temperatures.

Q4: Is the oil immersed distribution transformer suitable for outdoor use?

A: Yes! The oil immersed distribution transformer's sealed design and corrosion-resistant casing make it durable for outdoor installations. It also meets 50/60Hz frequency adaptability for global projects.
