33kV / 35kV Dry-Type Transformers
Cast-resin solutions for medium-voltage projects.
Configured around your power requirements.
Engineered for Medium-Voltage Power Distribution
YIMENG 33kV / 35kV dry-type transformer solutions are configured for medium-voltage power distribution in industrial plants, commercial developments and infrastructure projects. Cast-resin insulation and a three-phase design provide an oil-free option for protected indoor electrical rooms. Specify the primary voltage, secondary voltage and rated capacity around your network and load requirements.
For a 33kV dry-type transformer or 35kV cast-resin transformer project, review natural-air (AN) or fan-assisted (AF) cooling, winding material, enclosure protection and temperature monitoring. The final configuration should account for load profile, installation altitude, ambient temperature, ventilation and maintenance access.
For coastal facilities and demanding industrial environments, include humidity, salt exposure and site protection requirements in the enquiry. Send your insulation coordination, impedance and loss requirements to support engineering review and a project-specific quotation.
