Whether you need a transformer for a manufacturing plant, a transportation hub, or a government facility, our 35kV electrical transformer is engineered to meet your needs.

Key Advantages

Exceptional Mechanical Strength and Thermal Stability

Our industrial dry-type power transformer features a reinforced cast resin winding structure that provides excellent mechanical strength and resistance to short-circuit forces. The transformers also exhibit outstanding thermal stability, allowing them to handle overloads without compromising performance or lifespan. This ensures reliable operation even during peak demand periods.

Low Partial Discharge and High Reliability

We employ advanced manufacturing processes and strict quality control measures to ensure that our transformers have extremely low partial discharge levels. This minimizes the risk of insulation failure and extends the service life of the transformer. Our 35kV class dry-type power transformer has a proven track record of reliability in thousands of installations worldwide.

Superior Fire Safety Performance

The dry-type design of our transformers eliminates the risk of oil fires and explosions, making them ideal for installation in fire-sensitive locations. The cast resin insulation is self-extinguishing and does not produce toxic fumes in the event of a fire, ensuring the safety of personnel and property.

Long Service Life and Low Maintenance

Our fire-resistant dry-type transformer is built to last, with a service life of 25 years or more. The dry-type design requires minimal maintenance, eliminating the need for oil changes, filtration, and other routine tasks associated with oil-immersed transformers. This reduces downtime and lowers the total cost of ownership.
