Product Category: Distribution Box

This product is the GGD‑type AC low‑voltage fixed‑type power distribution cabinet, specially designed for AC 380 V, 50 Hz low‑voltage power distribution systems. It serves for power conversion, distribution and control of power, lighting and distribution equipment for power consumers such as power plants, substations, industrial and mining enterprises. The main busbar rated current can reach up to 3150 A. It features high short‑circuit breaking capacity, excellent dynamic and thermal stability, flexible electrical schemes and convenient assembly. With an innovative structural design and IP30 ingress‑protection rating, it complies with IEC 61439‑1 and GB 7251 standards. It is a mainstream upgraded product for domestic low‑voltage switchgear assemblies.

‑ Rated Voltage: AC 380 V, 50 Hz
‑ Rated Insulation Voltage: 660 V
‑ Main Busbar Rated Current: 1000 A ~ 3150 A
‑ Rated Short‑time Withstand Current: 15 kA ~ 50 kA
‑ Ingress Protection Rating: IP30
‑ Compliance Standards: IEC 61439‑1, GB 7251.1, GB 7251.2
‑ Ambient Operating Temperature: ‑25 ℃ ~ +40 ℃, Altitude ≤ 2000 m
‑ Protection Functions: Overload, short‑circuit, under‑voltage and over‑voltage protection

① High short‑circuit breaking capacity. The rated short‑time withstand current reaches a maximum of 50 kA. Superior dynamic and thermal stability enables the cabinet to withstand high short‑circuit current impacts for safe and reliable operation.

② Flexible configuration. Adopting a general‑purpose cabinet structure with modular‑designed components and 20‑module mounting holes, it delivers high part universality. Various functional units including incoming cabinets, outgoing cabinets, capacitor compensation cabinets and metering cabinets can be custom‑configured for easy assembly and strong practical performance.

③ Innovative cabinet construction. The enclosure is assembled with partial welding using 8MF cold‑formed steel profiles, providing high structural strength, aesthetic appearance and convenient installation and maintenance.

④ Reliable ingress protection. The standard IP30 rating prevents finger contact with live components and blocks solid foreign objects larger than 2.5 mm, making it suitable for indoor power‑distribution rooms.

⑤ Comprehensive product series. The full‑range portfolio covers diverse operating conditions to satisfy distribution demands from various industries and project scales. It can be deployed as an upgraded alternative for low‑voltage switchgear assemblies.

Q1: What does “GGD” stand for in GGD‑type distribution cabinets?
A: GGD is the Pinyin abbreviation for “Fixed‑type Low‑voltage Distribution Cabinet”. It denotes an indoor fixed‑mount low‑voltage switchgear, differentiating it from drawer‑type and draw‑out distribution cabinets.

Q2: What is the maximum rated current of a GGD distribution cabinet?
A: The main busbar of the standard model reaches a maximum rated current of 3150 A, catering to high‑current distribution requirements of large industrial plants and large commercial buildings.

Q3: What are the differences between GGD, GCS and GCK distribution cabinets?
A: GGD is a fixed‑type cabinet with permanently installed components; power shutdown is required for maintenance. GCS and GCK are draw‑out‑type cabinets with removable drawer units. Components can be inspected or replaced without cutting off power supply, enabling easier maintenance for applications requiring high power‑supply continuity.
