The 10kV SGB series dry-type transformer is a high-performance transformer designed for harsh environments, high fire-safety requirements, and fluctuating load conditions.

Unlike cast resin transformers, the SGB series adopts VPI (Vacuum Pressure Impregnation) technology combined with NOMEX insulation, providing excellent thermal performance, superior safety, and long service life.

It is especially suitable for environments with:

• High humidity
• Heavy pollution
• Large load fluctuations
• Strict fire safety requirements

Typical applications include:

• Airports and power plants
• Metallurgical industries
• Hospitals and high-rise buildings
• Ticari merkezler
• Petrokimya ve nükleer tesisler
