Key Features

Why Engineers Choose GGD

Datasheet-backed advantages for low-voltage combining and distribution duty.

🧩

Universal, Modular Cabinet

Cold-bent steel frame welded from standard bar steel sections, with a 20-module mounting-hole pattern for high component interchangeability across projects.

🌬

Heat-Rejection Design

Ventilation slots sized to cabinet loading are built into the upper and lower ends of every frame to manage internal temperature rise during continuous operation.

🚪

Sealed, Hinged Doors

Rotation-axis hinged doors with a rubber gasket strip compress against the frame on closing, preventing direct impact damage and raising the effective door protection grade.

🛡

Selectable Protection Grade

Standard build is IP30; the same frame platform can be configured from IP20 up to IP40 to match indoor environmental conditions.

Applications

Where GGD Fits Best

Optimized for low-voltage switching and distribution duty in solar and hybrid energy plants.

🔆

Low-Voltage AC Combining

Combines multiple inverter AC outputs ahead of the plant's step-up transformer, within a single bolted, modular cabinet lineup.

💡

Site Power & Lighting Distribution

General power and lighting distribution for inverter stations, O&M buildings and substation auxiliary loads.

🏭

C&I Plant LV Switchboards

Economical fixed-type LV switchboard for commercial and industrial PV sites where drawer-type withdrawability is not required.

🔋

BESS Auxiliary Distribution

Low-voltage distribution for battery storage block auxiliary systems — HVAC, fire suppression, lighting and controls.

FAQ

What Engineers Ask About GGD

Datasheet-driven answers for procurement teams and switchgear designers.

What is the rated current of the GGD switchgear?

GGD is built in three frame sizes — GGD1 (1000A), GGD2 (1500A) and GGD3 (3150A, also listed as 2500A) — all at 380V rated working voltage, 50Hz.

What protection degree does the GGD cabinet carry?

Standard protection is IP30. The frame and door design allow selection anywhere from IP20 to IP40 depending on the installation environment.

Is GGD a fixed-type or withdrawable switchgear?

GGD is a fixed-type (non-withdrawable) switchgear — breakers and components are bolted directly to the frame. For a withdrawable, drawer-type low-voltage switchgear, see the MNS product line.

What is the short-circuit breaking capacity of the GGD?

Rated short-circuit breaking current is 15kA for the GGD1 frame, 30kA for GGD2, and 50kA for GGD3, with corresponding 1-second short-time withstand ratings of 15kA, 30kA and 50kA.

Can GGD be used for low-voltage AC combining in a PV plant?

Yes. GGD's modular cabinet system and current range up to 3150A suit low-voltage AC combining, feeder distribution and control ahead of the medium-voltage interconnection point in utility-scale and C&I PV plants.

What standards does GGD comply with?

GGD complies with IEC 60439 (the low-voltage switchgear and controlgear assemblies standard, now superseded by the IEC 61439 family) and the Chinese national standard GB 7251.1.
