Connections
Start with the network voltages and connection arrangement. Review the terminal or cable interfaces against your system and project drawing.
- Primary Voltage
- 66 / 110 / 115 / 132 kV
- Secondary Voltage
- 6 / 10 / 11 / 33 / 35 kV
Oil Immersed Transformer
110 kV Three Phase Oil-Immersed Power Transformer
A high-voltage oil-immersed power transformer platform for transmission substations, renewable collector stations and utility grids.
- Capacity range
- Up to 100,000 kVA
- Voltage class
- 110 kV
Overview
Explore the configuration.
Use the published platform to begin a project-specific review of the network connection. The requested voltage class, insulation coordination, regulation and test scope must be stated together rather than selected independently.
Insulation & cooling
Review the insulating liquid and cooling arrangement for the duty. Confirm the compatible options, installation clearances and liquid containment in the project design.
- Cooling
- ONAN / ONAF
- Insulation class
- Class A
Installation
Plan the footprint, access and cable routes using the approved outline drawing. Share the installation environment so the mechanical interfaces can be reviewed.
- IP class
- IP54
- Environment
- Outdoor

No. Submit the actual operating voltages and utility requirements. Maximum equipment voltage, insulation levels, frequency, taps and required tests need to be confirmed in the technical proposal.
What do you need to prepare a quotation?
Start with your email and a short description. Tell us what you want to power, replace or purchase. You can send known ratings or a drawing, but you do not need to know every specification.
How are lead time, warranty and delivery agreed?
These are defined in the project quotation after reviewing the technical scope, quantity, destination and document requirements.
