10kV / 11kV Dry-Type Transformers

Air-cooled power distribution.
Configured for your project.

Engineered for Reliable Indoor Power Distribution

YIMENG 10kV / 11kV dry-type transformers provide a configurable solution for power distribution projects in residential communities, commercial buildings, industrial plants and infrastructure facilities. The cast-resin three-phase design uses high-quality insulation materials with an air-cooled structure, delivering reliable performance for indoor installations.

Natural-air (AN) and fan-assisted (AF) cooling configurations are available to suit different load requirements. Temperature monitoring, ventilation and access requirements should be reviewed as part of the project design to ensure safe and stable operation.

For projects in coastal areas or other environments with higher humidity or salt air exposure, site conditions, enclosure protection, insulation levels and temperature rise limits should be carefully evaluated. Please share your project requirements including rated capacity, voltage ratio, installation location and operating conditions, and YIMENG can provide a confirmed model configuration and quotation.
