GGD Low-Voltage Distribution Cabinet: Key Features & Typical Use
A Fixed Board That Is Easy to Inspect
Because the GGD uses fixed mounting rather than drawers, every breaker and terminal is visible once the door is open. For maintenance teams who prefer to inspect and torque connections directly, that removes an entire class of hidden contact problems and makes thermal imaging surveys faster to carry out.Rigid 8MF Frame and Coated Shell
The cabinet body is cold-rolled steel finished with light grey epoxy powder electrostatic coating, and the frame is built from 8MF section steel with aluminium-zinc coated support beams, bolted and welded into one rigid assembly. The result is a cabinet rated to carry 1000 kg and to stay dimensionally straight over a long service life.Ventilation Without Moving Parts
Ventilation openings are provided at the lower front, the upper rear, the lower rear, the top and the bottom of the enclosure. Warm air rises and leaves through the upper openings while cooler air enters low down, so the sealed cabinet creates its own natural ventilation path and dissipates up to 1250 W with no fans and nothing to service.Eight Size Combinations for Layout Freedom
The GGD is available in eight width and depth combinations from 600 to 800 mm wide and 400 to 600 mm deep, all at 2200 mm nominal height. That lets a switchroom be laid out around the load and the cable trench instead of around one enclosure size, and the standard 2200 x 800 x 600 mm shell keeps spares and documentation simple.GGD Low-Voltage Distribution Cabinet Specifications & Technical Data

GGD — a Fixed Low-Voltage Distribution Cabinet for Substations and Plants
Some switchrooms do not need drawers. Where the incoming supply is stable, the load list is settled and the maintenance team prefers to see every connection, a fixed board is simpler, cheaper to own and faster to inspect. The GGD is that board: a 2200 mm cabinet in eight width and depth combinations, up to 1000 kg of load and 1250 W of dissipation.In specifications this equipment is called a GGD fixed low-voltage distribution cabinet, a low-voltage switchboard or simply a fixed distribution panel, and it is usually compared with withdrawable boards on the same enquiry. Fixed construction suits sites where the load list is settled and the maintenance team prefers to see every connection; if the outgoing ways are likely to change often, a withdrawable platform is worth pricing at the same time.The structure is 8MF section steel with aluminium-zinc coated support beams, bolted and welded into one rigid frame, clad in cold-rolled steel with a light grey epoxy powder finish. Ventilation openings at the lower front, upper and lower rear, top and bottom let the enclosure form a natural chimney path, so cooling requires no fans and no maintenance.The GGD is used in substations, industrial plants, mining sites and large commercial and infrastructure buildings where a straightforward low-voltage distribution board is the correct engineering answer. LYE manufactures the shell and frame in-house and can adapt busbar arrangements and internal mounting to your drawings.Factory-Direct GGD Low-Voltage Distribution Cabinet Manufacturer & OEM / ODM
We Manufacture, You Brand
LYE Technology (Zhejiang) Co., Ltd. is a national high-tech enterprise and manufacturer in Wenzhou, China: sheet-metal fabrication, welding, powder coating, busbar machining and final assembly run on our own factory lines, and every unit is function-tested before it leaves the works. A GGD Low-Voltage Distribution Cabinet that reaches your site carries the routine test behind it, not just the rating on the nameplate.We are one of the Top 10 Brands of China's small power distribution boxes and a drafter of national standards in this category, and we hold ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification. Because we are the manufacturer rather than a trading company, our sales engineers quote from your drawing in factory-direct terms, and OEM or ODM work is produced on the same lines as our standard products.For the GGD we fabricate the 8MF frame and the cold-rolled steel cladding on our own lines, so a non-standard internal mounting arrangement is a drawing change rather than a new product.- OEM branding — custom colours, laser marking and your own project or retail packaging, applied at the factory.
- ODM options — ratings, configurations and internal layouts built around your drawings or single-line diagram.
- Certification — ISO9001, ISO14001, ISO45001, CCC, CE and TUV, with test documents supplied per project.
- MOQ — flexible quantities for a project or a trial order, with mixed types welcome in one shipment.

GGD Low-Voltage Distribution Cabinet Buying Guide from the Manufacturer
The GGD is ordered by size combination and internal arrangement rather than by drawer schedule. These are the points we confirm before production.
- Confirm the duty: incoming distribution, sub-distribution or terminal distribution in the switchroom.
- Fix the electrical parameters including rated voltage, rated current and short-circuit withstand.
- Choose the width and depth combination from the eight available, all at 2200 mm nominal height.
- Confirm the internal arrangement, busbar run and cable entry direction.
- Send the single-line diagram, quantity and any required shell colour or marking.
- Approve drawings, then production with routine testing and dispatch with documentation.

What is a GGD low-voltage distribution cabinet?
It is a fixed low-voltage distribution cabinet used in substations, industrial plants, mining enterprises and large commercial or infrastructure buildings. It is built on an 8MF steel frame with a light grey epoxy powder coated cold-rolled steel shell, rated 2200 mm high, able to carry 1000 kg and to dissipate 1250 W through natural ventilation, with enclosure protection IP30.What is a GGD cabinet used for?
It handles incoming and outgoing low-voltage distribution where a simple, fully accessible fixed board is preferable to a withdrawable design. Typical duties are substation and plant-room distribution, sub-distribution inside large buildings and terminal distribution, and because every breaker and terminal is visible with the door open, it suits maintenance teams who inspect and torque connections directly.What is the difference between fixed and withdrawable distribution cabinets?
A fixed cabinet bolts the breakers and devices in place, so a fault means isolating the cubicle before repair; it is simpler, cheaper to own and easier to inspect. A withdrawable cabinet mounts devices on trucks that can be exchanged while the busbar stays energised, which shortens outages but adds mechanism, interlocking and cost. The choice usually follows how critical continuity of supply is at that board.Who manufactures GGD low-voltage distribution cabinets?
This is one of the most widely produced cabinet types, so buyers should look beyond the name to how the shell and frame are actually made. Ask whether the 8MF frame, the cold-rolled steel cladding and the powder coating are produced in house, and whether the finished board is routine tested before dispatch. LYE manufactures the GGD shell and frame in Wenzhou and holds ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification.How much does a GGD distribution cabinet cost?
Indicative factory-direct pricing is roughly US$1,500 to US$6,000 per cubicle, depending on the size combination, the internal arrangement, the busbar rating and the quantity ordered. Fixed boards are priced largely from the enclosure and the busbar work, so once the single-line diagram and cable entry direction are fixed the quotation is straightforward and easy to compare between suppliers.

Use a distribution box for final circuits and compact branch protection; use a cabinet when the project needs larger incoming capacity, more feeder groups, metering, busbars or greater internal separation. The final choice should be checked against the single-line diagram, device list, available installation space and local project rules.
Provide the device schedule, circuit quantity, component dimensions, cable-entry direction, mounting method and required spare capacity. LYE also reviews door clearance, bending radius, heat-producing devices and the usable depth behind the mounting plate before confirming an enclosure size.
Start with the actual exposure to dust, rain, cleaning water and accidental contact rather than choosing the highest number by default. Cable entries, ventilation, door seals and installation workmanship affect the finished assembly, so the target rating and verification basis must be confirmed for the specific product and project.
Coated or galvanized steel is commonly considered for general indoor service, stainless steel for humid or corrosive locations, and engineering plastic for lightweight non-metallic applications. Material grade, thickness, UV exposure, chemical contact and earthing requirements must be confirmed against the installation environment.
Share the component heat load, ambient temperature, solar exposure, duty cycle and allowable internal temperature. LYE can then review enclosure volume, spacing, ventilation or fan provisions, sun shields, heaters or drainage details; the final thermal design remains tied to the installed equipment and site conditions.
Yes. A dimensioned drawing is preferred, but a physical sample and clear reference photographs can also start the review. Material, thickness, openings, hardware, finish, labels, inspection points and packing are recorded before sampling or repeat production.
PDF and common 2D CAD drawings are suitable for most enclosure enquiries, while 3D files can help with complex assemblies. Include a revision number, units, tolerances and component references; file compatibility and any missing production information will be confirmed during review.
A sample or first article can be arranged for a new or customized product. The approval plan should identify dimensions, openings, fit, appearance, hardware, labels and packaging, together with the sample cost and timing agreed for the actual order.
Available documents may include approved drawings, packing lists, dimensional or appearance inspection records, product data and certificates applicable to the confirmed model. Destination-specific declarations or third-party testing must be requested before order placement so availability and scope can be verified.
Lead time is confirmed after the product scope, quantity, sample requirement and finish are known. Packing is reviewed against product weight, surface protection, destination and shipping method; if an issue is found after delivery, send the order reference, label, photographs and quantity affected so it can be traced and reviewed.
