FAQs

 

What applications is the SG Three-phase Air-immersed Transformer best suited for?

It is ideal for machine tool control systems, mechanical equipment power distribution, industrial lighting, and signal circuits requiring stable low-voltage power transformation and electrical isolation.

 

What are the advantages of the air-immersed design?

The natural air cooling system offers efficient heat dissipation without oil, making it fire-resistant, low-maintenance, and environmentally friendly, while reducing noise and energy loss.

 

What types of enclosures are available?

You can choose between exposed-type for controlled environments and fence-type with a protective steel shell for added safety and durability. Higher-capacity models (≥80kVA) include fans, meters, and wheels for easy operation.

 

How customizable is the SG transformer?

CHINT allows customization of input/output voltages, enclosure type, and connection configuration (Y/Δ) based on user requirements. Models above 300A input current require special design adjustments.

 

What environmental conditions can it operate in?

It operates reliably in ambient temperatures of −5°C to +40°C, with humidity up to 95%, at altitudes below 2000m, and in non-corrosive, non-explosive indoor environments.
