APPLICATION & DUTY
Where GGD fits
GGD is fixed-type low-voltage switchgear for power and lighting distribution. Switching and protective devices are mounted in a cabinet arrangement selected around the feeder schedule. It is suited to projects that require fixed circuits with clearly defined access, connections and maintenance provisions.
APPLICATION / 02
Building power and lighting
For distribution rooms using fixed switching assemblies and coordinated outgoing protection.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Cold-formed steel framework
The cabinet uses an 8MF cold-formed steel structure with partly welded assembly. Modular mounting positions support the internal electrical layout.
DETAIL / 02
Fixed circuit construction
Power circuits and installed switching devices remain fixed in their mounting arrangement. Equipment access and isolation requirements should therefore be planned with the switchroom design.
DETAIL / 03
Removable access components
Removable doors and top covers assist assembly and access to the busbar area. Door grounding connections form part of the cabinet arrangement.
DETAIL / 04
Compensation coordination
Where reactive-power compensation is required, identify the associated compensation section in the line-up and coordinate its bus connection and protective devices.
DEFINE THE SELECTED ASSEMBLY
Configuration & installation interfaces
Match the installation drawing, cable routes, clearances and electrical duty for the selected equipment.
Illustrative working scene- Electrical duty
- Provide the circuit schedule, bus rating and required fault withstand.
- Devices and metering
- Specify switching devices, trip functions, metering and outgoing protection.
- Enclosure requirements
- Define access, cable entry, finish and the required enclosure protection for the site.
Installation & connection checklist
- Confirm cabinet dimensions and line-up connection positions.
- Provide cable or busduct termination drawings.
- State required access and isolation arrangements for maintenance.
- Agree the actual configured rating rather than assuming one maximum applies to every GGD variant.
Operating conditions for the listed configuration
- Indoor installation; altitude up to 2,000 m.
- Ambient −5 to +40 °C; 24-hour average up to +35 °C.
- Relative humidity up to 50% at +40 °C; higher humidity at lower temperatures requires consideration of condensation.
State any different ambient temperature, altitude, humidity, dust, salt or corrosive exposure when requesting the installation-specific configuration.
