Overview
The GGD-Type Incoming Cabinet is a critical component in low voltage systems, designed as the primary electrical incoming panel. It connects to
external sources (e.g., grids or power supply cabinets) and safely distributes electricity to downstream low voltage distribution switchboards or
equipment. As part of GGD switchgear, it combines robust structure with efficiency, equipped to protect circuits and ensure uninterrupted flow. Ideal
for 3-phase panels, it bridges supply and end-use, vital in industrial and commercial power setups.
Core Components and Features
Core components include intelligent universal circuit breakers, the main protective devices preventing overloads, short circuits, and faults. It features
3-phase panel elements, ensuring compatibility with standard systems. Key functions: receiving power from external sources (e.g., supply cabinets),
filtering/stabilizing current, and distributing to downstream low voltage GGD switchgear. It acts as a hub for monitoring power flow, with components
enabling easy integration into larger networks. Its design ensures efficient management, linking primary and secondary distribution to maintain stability.
Design and Compliance
Design:
The cabinet features a modular and compact design, which significantly simplifies both installation procedures and daily maintenance work. It is specifically
engineered to support flexible custom configurations, perfectly aligning with the diverse requirements of custom GGD power distribution cabinets. Its
sturdy and robust enclosure forms a reliable barrier, effectively shielding internal components from dust accumulation, moisture intrusion, and external
impacts, thereby ensuring long-term structural durability and stable performance.
Compliance:
This cabinet strictly adheres to a comprehensive set of international and regional standards governing low-voltage switchboards, fully meeting all specified
safety protocols and performance benchmarks. Such strict compliance not only guarantees safe and stable operation across a wide range of application
environments but also minimizes potential safety hazards while enhancing global system compatibility for seamless integration.

Key Advantages
Superior Reliability:
Equipped with intelligent universal circuit breakers, it offers real-time monitoring of current, voltage, temperature, enabling rapid response to faults. This
minimizes downtime, critical for avoiding production halts or service disruptions. Robust components reduce replacements, enhancing durability.
Seamless Integration:
As core low voltage GGD switchgear, it connects seamlessly with 3-phase panels, supply cabinets, and downstream switchboards. This fits new/retrofitted
systems, adapting to varying architectures, maintaining performance with grids, generators, or UPS.
Tailored Customization:
A variant of custom GGD cabinets, it offers extensive options: rated current (630A-3200A), enclosure size, protection level (IP30-IP65), and add-ons like
metering/remote monitoring. Flexibility aligns with unique project needs.
Enhanced Safety:
Beyond global standards, it has multiple protections: flame-retardant steel enclosure with insulated barriers, anti-misoperation interlocks, and heat-dissipating
structures, reducing shocks, errors, and fire risks.
Cost-Efficient Maintenance:
Modular design enables easy access to components, streamlining inspections/repairs, cutting time/labor costs. Energy-efficient parts minimize loss; standardized
GGD framework ensures readily available replacements, lowering lifecycle costs.

Application Scenarios
Heavy Industry Sector:
In factories, steel mills, and automobile manufacturing plants, this equipment acts as a primary incoming panel to manage high-power three-phase power supply
and distribute electricity to production lines, machinery, and auxiliary GGD switchgear. Its robust structure can resist vibrations and dust, and the overload
protection function also effectively prevents equipment damage.
Commercial/Public Building Sector:
For places with complex electricity demand such as shopping malls, airports, and hospitals, this equipment receives the main power supply and then distributes
electricity to three-phase distribution cabinets, which in turn power lighting, HVAC systems, elevators, and backup equipment like fire pumps. Its customized
design fits narrow spaces, and the remote monitoring function can optimize efficiency to ensure uninterrupted power supply.
Urban Infrastructure Sector:
This category covers urban substations and municipal/environmental protection projects. In substations, the equipment connects medium-voltage transformers
and secondary switchboards, balances three-phase loads to avoid grid overloads, and complies with standards to integrate into municipal power grids. In scenarios
like wastewater treatment plants, pumping stations, and solar power plants, its IP54 weather-resistant enclosure can withstand harsh environments, and it can also
handle fluctuating three-phase loads to adapt to changes in renewable energy output, ensuring stable operation of facilities.
Critical Power Support Sector:
Data centers rely on its reliability. It connects to redundant power supply cabinets such as generators and UPS systems, and delivers stable electricity to server
racks through three-phase distribution cabinets. With millisecond-level fault response, it can instantly activate backup power supplies, ensuring the continuous
operation of systems like cloud services, finance, and communications.
