Oil Immersed Transformer
A three-phase oil-immersed platform for 10 kV distribution in commercial, industrial, residential and renewable-energy projects.
Overview
Start with the network supply, required secondary voltage and connected load. For a replacement, a readable nameplate and site photos help identify the electrical duty and installation interfaces without guessing the model.
Start with the network voltages and connection arrangement. Review the terminal or cable interfaces against your system and project drawing.
Review the insulating liquid and cooling arrangement for the duty. Confirm the compatible options, installation clearances and liquid containment in the project design.
Plan the footprint, access and cable routes using the approved outline drawing. Share the installation environment so the mechanical interfaces can be reviewed.
