Product Description
560kVA Cast Resin Dry Type Isolation Transformer 440V to 390Y/225V with IEC60076 Standard

Best for:

Cabinet-integrated indoor power systems, industrial equipment and high-humidity or coastal projects requiring 560kVA cast resin dry type isolation from 440V to 390Y/225V.


Customizable Specifications:

kVA, primary voltage, secondary voltage, frequency, vector group, enclosure/IP requirement, cooling method, tap range, ambient condition, altitude, quantity, destination port and required accessories.


Product Overview

This 560kVA cast resin dry type isolation transformer is designed for cabinet-integrated indoor power systems, industrial equipment power supply, and high-humidity or coastal projects where moisture exposure and fire behavior need to be considered. It converts 440V Delta input to 390Y/225V Wye-N output, making it suitable for three-phase systems that require a neutral connection.

The transformer uses cast resin windings, copper conductors, a silicon steel core, F-class insulation, and C2 / E2 / F1 dry type classification. Its AN/AF cooling arrangement includes natural air cooling and fan-assisted heat dissipation for indoor operating conditions. The IP00 open structure is intended for installation inside an electrical cabinet, enclosure, or integrated power system.

With Dyn11 connection, five-position primary-side tapping, and IEC60076 design basis, this unit provides clear parameters for project selection, electrical room layout, equipment integration, and voltage matching during commissioning.

Standard Features

  • Cast resin windings: Provide an oil-free insulation structure for indoor electrical rooms, equipment cabinets and integrated power systems.
  • F-class insulation with C2 / E2 / F1 rating: Supports indoor projects where temperature rise, humidity exposure and fire behavior need to be considered.
  • Copper winding and silicon steel core: Matched with the 560kVA rating and 440V to 390Y/225V voltage conversion.
  • AN/AF cooling system: Natural air cooling with fan-assisted forced air cooling for additional heat dissipation.
  • Temperature control system: Temperature controller and PT100 sensors help monitor winding temperature during operation.
  • Five-position tap terminals: 418V / 429V / 440V / 451V / 462V tapping allows voltage adjustment during commissioning.
  • IP00 open structure: Suitable for installation inside an electrical room, enclosure or customer-provided cabinet.
  • Dry type installation: No insulating oil is used, so oil pit planning is not required where the project design permits.
