Product Overview

GGD low-voltage fixed-type switchgear is designed for indoor 380 V, 50 Hz power distribution and control. With a main busbar rated current of 400–1,600 A, it accommodates incoming supplies and outgoing distribution circuits for industrial plants, power facilities and infrastructure projects.

The fixed-mounted arrangement provides a straightforward solution for installations with relatively stable loads and circuit configurations. An accessible internal layout supports wiring inspection and routine servicing, while cabinet arrangements and component selection can be planned around the project’s load schedule, protection requirements and installation space.

Icu and Ics ratings apply to the selected circuit breaker and must be confirmed against its rated operational voltage. Final assembly ratings, dimensions and circuit arrangements are subject to the approved project documentation.

Product Advantages

Economical Fixed-Type Design

The fixed-mounted arrangement avoids the additional withdrawal mechanisms used in drawer-type switchgear. It offers an economical option for projects where circuit replacement speed is less critical and the distribution layout is expected to remain relatively stable. Final cost depends on the selected components and configuration.

Straightforward Mechanical Structure

Fixed-mounted switching devices and connections provide a simple internal arrangement with fewer moving mechanisms associated with circuit withdrawal. This suits installations that prioritize conventional operation and planned maintenance.

Accessible Layout for Inspection and Servicing

An organized component layout and clear wiring routes help qualified personnel identify circuits, inspect connections and carry out routine servicing. Maintenance access and isolation requirements should be considered when planning the cabinet arrangement.

Configurable Distribution Circuits

Incoming supplies, outgoing feeders, metering and other required functions can be arranged to suit the project’s electrical design. Circuit quantities, protective devices and component ratings are selected according to the connected loads and system requirements.

Defined Ratings for Equipment Selection

The supplied GGD configuration has a rated short-time withstand current of 30 kA and a rated peak withstand current of 63 kA. These ratings provide reference values for selection against the installation’s prospective fault current and required withstand duration.

Standardized Layout for Project Planning

A standardized cabinet arrangement supports equipment selection, installation planning and spare-parts management. Multiple cabinet sections can be planned as a distribution lineup, with dimensions, connections and future capacity confirmed during project design.

Typical Applications

Power Plants and Substations

Low-voltage auxiliary distribution for power, lighting and supporting equipment. GGD cabinets can serve as distribution and control assemblies where their ratings match the system requirements.

Industrial Plants and Workshops

Main and secondary distribution for production lines, machine tools, fans, pumps and other plant loads. The fixed-type arrangement is particularly suitable for circuits that do not require frequent replacement or reconfiguration.

Mining and Related Facilities

Power distribution for equipment and supporting services in suitable indoor electrical rooms, subject to the site’s environmental and protection requirements.

Infrastructure Projects

Low-voltage distribution for ports, airports, railway facilities and highway infrastructure, with circuit arrangements selected to suit the connected equipment and operating conditions.
