Engineering handoff

Prepare an RMU or GIS load break switch specification

Match the switch to the project electrical duty and installation interface before requesting quotation. The drawing, cabinet GA, and operating requirements let engineering review the correct configuration instead of quoting a generic switch.

Illustrative RMU / GIS switch interface. Confirm the actual busbar, fuse, cable, bushing, interlocking, earthing, mounting, and clearance arrangement against the project documents.

Define the installation and operating interface

Cabinet mounting, clearances, and phase spacing

Provide the cabinet general arrangement, mounting pattern, operating position, phase spacing, and accessible working envelope.

Busbar, cable, and bushing connection interface

State the terminal interface, conductor orientation, connection arrangement, and available cable or bushing clearance.

Operating mechanism, interlocking, and earthing

State the required manual or motor operation, shaft direction, interlock logic, earthing arrangement, and control supply.

Send an engineering RFQ package

Keep the voltage family, rated current, duty, project interface, quantity, drawing revision, and required documents together so the review starts from the right configuration.

OEM / ODM configuration

For non-standard work, identify the cabinet envelope, interface constraints, operating arrangement, and nameplate or marking requirements.

Inspection and traceability evidence

State the routine-test, inspection, traceability, and quality records required for the selected configuration.

Delivery and packing scope

State the destination, quantity, shipment basis, packing expectations, and requested delivery window.

SF6 load break switch selection FAQ

Use the published data as an engineering starting point, then confirm the exact model, duty, insulation coordination, and cabinet interface against the project documents.

Which indoor SF6 load break switch voltage families can be reviewed here?

The page provides drawing-backed 12 kV and 24 kV, 630 A configuration data and a separate 35 kV layout reference. Open each family card to keep the parameter table and drawing together during initial RMU or GIS selection.

Which duty and interface inputs are needed to select a load break switch?

Start with system voltage, normal current, insulation coordination, required switching duty, earthing and interlocking arrangement, operating mechanism, control supply, and the cabinet mounting and connection interface. Confirm any project-specific interruption duty separately.

What files should accompany an RMU or GIS load break switch RFQ?

Send the cabinet general arrangement, single-line diagram where available, connection or bushing detail, mounting pattern, operating arrangement, quantity, applicable standard, drawing revision, and available nameplate or site photographs.

Why must the applicable standard be included in the enquiry?

Switches and switch-disconnectors are specified against a defined duty and test basis. State the applicable project standard, such as IEC 62271-103 where relevant, so the engineering review can separate documented values from project-specific requirements.
