Air insulated Dry type transformer VPI

TAILI SG(B) air-barrier dry-type transformer( VPI) is designed for safe, reliable operation. It offers low losses, minimal partial discharge, low noise and great fire safety, with flame-retardant materials and no harmful emissions-making it environmentally friendly and maintenance-free.

Its compact, moisture-resistant design allows reliable performance even in dusty, humid, or harsh conditions.

Applications include: airports, hospitals, power plants, high-rise buildings, shopping malls, residential areas, petrochemical facilities, or other critical or high fire-safety place.

Taili Dry Type Transformers are designed and tested to meet IEC, IEEE, UL, and other international standards, ensuring acceptance in global projects and compliance with strict safety requirements.

VPI Dry-Type Transformers provide an environmentally responsible and cost-effective solution for a wide range of applications. Unlike traditional liquid-filled transformers, they minimize fire risks, reduce maintenance requirements, and eliminate the potential for environmental contamination, making catch basins unnecessary during installation.

· Environmentally friendly alternative to oil-filled transformers
· Low maintenance design
· Suitable for diverse applications
