Engineering specification
Prepare an RMU or GIS load break switch specification
Match the switch to the required electrical duty and installation interface before quotation. Send the cabinet layout, connection details, mechanism requirements, and quantity so the correct configuration can be prepared.
RMU and GIS interface guide: define the actual busbar, fuse, cable, bushing, interlocking, earthing, mounting, and clearance arrangement for the selected cabinet.
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 requirements
State the routine-test, inspection, traceability, and quality-document requirements for the selected configuration.
Delivery and packing scope
State the destination, quantity, shipment basis, packing expectations, and requested delivery window.
Continue your RMU and GIS component selection
Move from load-break-switch selection to the adjacent switching, monitoring, and operating components that share the same medium-voltage cabinet scope.
SF6 load break switch selection FAQ
Use the configuration data, intended switching duty, applicable standard, and cabinet interface together when preparing the enquiry.
Which SF6 load break switch voltage families are shown on this page?
The page presents 12 kV and 24 kV, 630 A configurations plus a 35 kV layout. Open each card to keep the technical table and engineering drawing together during 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, switching duty, earthing and interlocking arrangement, operating mechanism, control supply, cabinet mounting, and the connection interface.
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 should the applicable standard be included in the enquiry?
The applicable standard defines the switching duty and test basis for the requested configuration. State the project standard, such as IEC 62271-103 where relevant, together with any customer-specific acceptance requirements.
Request SF6 switch quotation.
Send the voltage, normal current, switching duty, applicable standard, cabinet interface, operating arrangement, quantity, destination, and available drawings for a configuration and quotation review.
