Make the technology choice clear
Different insulation systems.
Different product ranges.
State the required insulation system in your enquiry. The switchgear insulation category and the switching device’s operating medium must be checked separately.
On smaller screens, scroll the comparison horizontally.
| Insulation system | Product range | Selection note |
|---|---|---|
| SF6 gas-insulated | QCL-12 / QCL-24 | 12 kV and 24 kV product lines. Specify the voltage and required functional units. |
| Air-insulated | XGN15 | Air-insulated metal-enclosed switchgear. Confirm the switching device and its medium separately. |
| Solid-insulated | QCG / STQCG-12 | 12 kV, 50 Hz, SF6-free product line. Confirm the functional arrangement and applicable documentation. |
| Nitrogen / dry-air insulated | QCHB-12 | A separate, supplementary product line. Confirm the specified medium and project configuration. |
Product lines are not interchangeable. Ask about the required insulation system
Engineering documentation
Review the details before you decide.
Use the document centres to review available information. Ask for the model, configuration and revision that match your enquiry.
Quality, testing & inspectionProduct catalogues
Review the product range and request the current technical document for your selected model.
General arrangement drawings
Check layout information. Project dimensions and interfaces require an approved configuration drawing.
Test reports & scope
Check the report number, tested sample and individual tests before applying a report to a specification.
From project inputs to equipment supply
A clear next step at every stage.
Share your SLD or BOQ
Send your single-line diagram or bill of quantities, together with the project country, voltage and equipment requirements.
Align the project scope
Review the configuration, equipment supply boundaries, installation conditions and required technical documents.
Review the proposal
Check the technical proposal and quotation against your project requirements, quantities and agreed responsibilities.
Confirm equipment supply
Agree the final product scope, documents, commercial terms and delivery requirements before proceeding.
You can start with basic requirements and provide drawings later.
Start your project enquiryProject & partner support
Align equipment supply with local project requirements.
