GGD Low Voltage Distribution Enclosure & Auxiliary Materials
Complete one-stop solution: GGD type low-voltage distribution cabinets plus all auxiliary materials — copper busbars, cable accessories, DIN rails, earthing, insulation, cooling and control components — for fully assembled, standards-compliant power distribution systems.
Product Overview
GOHO supplies GGD type low-voltage distribution enclosures together with a complete range of auxiliary materials and electrical accessories, enabling a single-source procurement for the entire power distribution assembly.

GGD type low-voltage distribution enclosures are used for power distribution in power plants, mining enterprises, industrial facilities and transformer substations. These cabinets deliver reliable service and ensure all electrical distribution requirements are met for various industrial and commercial applications — controlling motor starting sequences, power distribution and lighting circuits.

Key Features
Nine reasons buyers choose GOHO GGD enclosures and auxiliary materials for their low-voltage distribution projects.
One-Stop Procurement
Enclosure plus every auxiliary material from a single supplier — eliminates multi-vendor sourcing, guarantees compatibility and shortens lead time from order to assembly.
Robust GGD Enclosure
Cold-rolled steel (1.5–2.0 mm) with epoxy powder coating for corrosion resistance and long service life in industrial, mining and substation environments.
High-Current Busbar System
T2 electrolytic copper busbars rated up to 3150 A with insulated supports and connectors — low contact resistance, reliable current carrying and easy expansion.
IP30 to IP54 Protection
Multiple ingress protection options to match the installation environment — from standard indoor IP30 to dust-tight IP54 for industrial and outdoor-adjacent areas.
Standards Compliant
Designed and tested to IEC 61439 and GB/T 7251, with CCC, CE and ISO 9001 certification — safe, reliable and accepted in international tenders and inspections.
Complete Cable Accessories
Cable lugs, glands, ties, heat-shrink tubing and markers — every termination and cable-management accessory needed for a clean, code-compliant installation.
Mounting & Wiring Hardware
DIN rails, mounting plates, chassis rails, terminal blocks, wire ducts and trunking — standard modular components for fast, flexible and maintainable internal assembly.
Earthing & Insulation
Copper earth bars, earthing screws and braids for protective bonding, plus insulating boots, phase barriers and silicone rubber sheets for safe phase separation.

Frequently Asked Questions
Common questions about GGD enclosures and GOHO auxiliary materials.
The package covers eight categories: enclosures (GGD cabinets, wall-mounted junction boxes, stainless steel enclosures), busbar systems (T2 copper busbars, supports, connectors), cable accessories (lugs, glands, ties, heat shrink, markers), mounting hardware (DIN rails, plates, chassis rails, brackets), earthing components, insulation materials, control accessories (terminal blocks, wire ducts, trunking, labeling) and cooling & ventilation accessories. Customers can order the full set or select only the categories required for their project.
The GGD enclosure supports a rated voltage of 400 V / 690 V and a main busbar rated current up to 3150 A. Short-time withstand current reaches up to 80 kA (1 s) with a peak withstand current of 176 kA, suitable for low-voltage main distribution in power plants, industrial plants and substations. The exact busbar cross-section (up to 120 × 10 mm, single or double stack) is selected according to your design current.
Yes. We offer customization for dimensions, door configuration (single/double, with or without observation window), cable entry direction (top/bottom/rear), color (standard RAL 7035 or custom RAL), degree of protection (IP30/IP40/IP54), form of separation (Form 2/3/4), internal layout and auxiliary component selection. Share your single-line diagram and site requirements and our engineers will propose an optimized configuration.
GGD is a fixed-type low-voltage distribution cabinet with components fixedly mounted — simple, economical and ideal for main distribution and motor control with infrequent maintenance. GCS is a withdrawable-type switchgear where function units can be plugged in/out for hot maintenance, making it better for high-reliability and frequent-switching applications. Both are available from GOHO; choose GGD for cost-sensitive main distribution and GCS for critical, maintainable systems.
Yes. The busbars, DIN rails, terminal blocks, cable accessories, earthing components and cooling accessories we supply are manufactured to industry-standard dimensions and are compatible with most mainstream low-voltage enclosure brands. We can also provide matched components as a complete kit for GGD, GCS, MNS, GCK and other switchgear types on request.
GOHO GGD enclosures are designed and tested to IEC 61439 (low-voltage switchgear assemblies) and GB/T 7251, and carry CCC, CE and ISO 9001 certifications. This makes them accepted for international tenders, third-party inspections and grid-connection audits worldwide. Type-test reports are available on request for your specific rated current and short-circuit ratings.
