10MVA Industrial cast-resin pad-mounted transformers are large-capacity, fully enclosed dry-type power distribution devices, which are perfectly compatible with the supporting needs of Prefabricated Substation and Compact Prefabricated Substation in harsh industrial environments. These transformers, as core power supply components, can well match the overall layout of Prefabricated Substation and Compact Prefabricated Substation, providing stable and reliable power support for the entire power system. With high integration and compact structure, they can be flexibly integrated into various Prefabricated Substation configurations, effectively meeting the power supply needs of industrial production, and laying a solid foundation for the stable operation of Prefabricated Substation and Compact Prefabricated Substation.
Cast-Resin Insulation: High-voltage windings use epoxy resin vacuum casting (IEC 60076-11 compliant), full insulation and maintenance-free, ideal for Compact Prefabricated Substation integration.
Pad-Mounted Structure: IP65 protection, outdoor-installable, directly placeable on concrete foundations, suitable for matching Prefabricated Substation outdoor layout.
Industrial-Grade Design: Withstands high loads, harmonics and extreme climates (-40°C to +70°C), adapting to Compact Prefabricated Substation industrial application scenarios.
Power Conversion: Steps down medium voltage (e.g., 35kV) to industrial voltage, supporting power supply for Prefabricated Substation and its connected large equipment.
Safety Isolation: Oil-free (F1 fire rating), suitable for flammable areas, reducing fire risks of Compact Prefabricated Substation.
Harmonic Suppression: Internal aluminum shielding (THD ≤8%), protecting precision equipment in Prefabricated Substation.
Overload Capacity: 120% load for 4h, 150% load for 1h (IEC 60076-12), meeting peak loads of Compact Prefabricated Substation.
