This cast coil dry type transformer utilizes epoxy resin insulation for superior environmental resistance. Rated 500 kVA with primary 12470V, secondary 480Y/277V. Specifically designed for data center and commercial building applications where low noise, fire safety, and maintenance-free operation are critical.

Key Selling Points

• Epoxy Resin Encapsulated Windings: Provides excellent moisture resistance, self-extinguishing fire behavior, and low partial discharge (source fact: company profile mentions epoxy resin cast dry-type transformers).
• Low Noise Level: Cast resin construction inherently dampens vibration, making it suitable for noise-sensitive environments (source fact: available image indicates use in data centers).
• UL Listed: Certified under UL file E531446, meeting ANSI/IEEE standards (source fact: UL cert).
• Compact and Lightweight: Small footprint reduces floor space requirements (source fact: company profile highlights compact size).
• High Fire Resistance: Epoxy resin is self-extinguishing, enhancing safety in occupied spaces (source fact: industry standard for cast resin).
