Connections
Start with the network voltages and connection arrangement. Review the terminal or cable interfaces against your system and project drawing.
- Primary Voltage
- 33 / 34.5 / 35 / 40 / 44 / 66 kV
- Secondary Voltage
- 6 / 10 / 11 / 20 / 22 kV
Pad Mounted Transformer
Up to 66 kV Three Phase Pad-Mounted Transformer (10 MVA)
A higher-voltage three-phase pad-mounted enquiry platform for distribution substations, renewable collector stations and industrial parks.
- Capacity range
- Up to 10 MVA
- Voltage class
- Up to 66 kV
Overview
Explore the configuration.
Check whether the required high-voltage interfaces and site arrangement fit a pad-mounted solution. Review insulation, clearances, terminations and access against the project specification before choosing the final construction.
Insulation & cooling
Review the enclosure and thermal arrangement as a complete assembly. Internal components and compartment layouts are confirmed in the project drawing.
- 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 pad-mounted

Explore the FactoryCan a standard pad layout be assumed for a higher-voltage project?
No. Provide the site plan, cable interfaces, required clearances and maintenance access. The project-specific arrangement and equipment boundaries must be confirmed before civil works or procurement.
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.
