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 / 35 kV
Dry Type Transformer
SC(B) Series 110 kV Cast Resin Dry-Type Power Transformer
A high-voltage cast-resin dry-type enquiry platform for utility substations, large industrial facilities and renewable-generation projects.
- Capacity range
- Up to 40,000 kVA
- Voltage class
- 110 kV
Overview
Explore the configuration.
Treat this high-voltage platform as the start of an engineering review. The exact voltage combination, insulation coordination, cooling arrangement and installation layout must be established for the project.
Insulation & cooling
Review the dry-type insulation and cooling arrangement for the operating environment. Airflow, enclosure and access requirements depend on the selected configuration.
- Cooling
- AN / AF
- Insulation class
- Class F / H
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
- IP23
- Environment
- Indoor / outdoor enclosed, -25°C to +40°C

No. Published options are reference information, not confirmation that every combination is available. Request a project-specific technical proposal covering ratings, insulation, cooling, interfaces and the required tests.
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.
