Product Overview
As a core fixed-type power distribution solution for global industrial and utility engineering, the GGD AC low voltage distribution cabinet features a front-access structural design, tailored for 50Hz AC power systems with 400V rated working voltage and 660V rated insulation voltage. Adopting industry-proven structure, high short-circuit withstand capacity and humanized operation design, this fixed low-voltage switchgear delivers outstanding stability and safety. It is widely deployed in power plants, urban substations, industrial manufacturing bases and commercial buildings worldwide, providing reliable, low-cost power distribution control for diverse medium and low-voltage power supply systems.
Key Features
Superior Short-Circuit Withstand Capacity:
Fully type-tested in strict accordance with international industry standards, the cabinet supports a rated short-time withstand current of 50kA/1s and a peak withstand current of 105kA. It can effectively resist instantaneous impact current caused by system short-circuit faults, providing dual safety protection for on-site operators and downstream electrical equipment.
Reliable Fixed Installation Structure:
Adopts integrated fixed mounting for circuit breakers and laminated copper busbars, optimizing internal wiring layout and reducing wiring loopholes and later maintenance points. The mature fixed structure guarantees long-term stable and 24/7 uninterrupted operation, perfectly matching continuous production and power supply scenarios of industrial enterprises.
Modular & Flexible Configuration:
Built with high-strength cold-rolled steel frame and full-height protective doors, supporting dual top and bottom cable entry modes and detachable side panels. It supports flexible configuration of metering modules, independent compartment layouts and customized internal circuits, which can be perfectly adapted to personalized system design requirements of different industrial and utility projects.
Excellent Indoor Operational Reliability:
Comes with standard IP40 protection grade (IP54 optional for customized demands), which effectively isolates external dust, moisture and debris from internal live parts. The built-in scientific natural ventilation structure reasonably dissipates operating heat, keeps equipment temperature rise within the international safe standard range, and avoids equipment aging and failure caused by overheating.
Durable for Harsh Working Conditions:
The whole cabinet is made of high-quality thickened cold-rolled steel plates, with professional anti-corrosion, anti-rust and electrostatic spraying surface treatment. It owns outstanding mechanical shock resistance and environmental adaptability, and can maintain stable performance in high-dust and conventional humid indoor industrial environments for long-term continuous service.
Low Total Operation Cost:
All internal components adopt standardized and serialized industrial design, with high universality and interchangeability. The standardized assembly process greatly simplifies on-site installation, system commissioning and daily maintenance work, effectively reducing the overall project investment and later operation and maintenance costs for customers.
