Our Low-Voltage Power Switchgear serves as the primary control and distribution hub for large-scale industrial and commercial power systems. Engineered to handle high-amperage loads up to 6300A, this switchgear assembly is the essential interface between the main power transformer and the facility's electrical infrastructure.
Designed with a modular "C-profile" or "8MF" framework, our switchgear offers exceptional flexibility, allowing for both fixed and withdrawable (draw-out) unit configurations. Whether utilized in a heavy-duty manufacturing plant, a data center, or a municipal substation, this power distribution board provides the high breaking capacity, advanced thermal management, and operator safety required for modern electrical grids.
High Breaking Capacity (Icu): Engineered to safely interrupt short-circuit currents up to 100kA, protecting downstream assets from catastrophic electrical failure.
Modular Segregation (Internal Partitioning): Supports Form 2b, 3b, and 4b internal separation. This ensures that the busbar, functional units, and cable terminals are physically isolated, preventing the spread of internal arcs.
T2 High-Purity Copper Busbar System: Utilizes 99.9% pure T2 copper with silver-plated joints. This reduces contact resistance, prevents oxidation, and ensures maximum conductivity even under full-load continuous operation.
Advanced Thermal Containment: Features integrated ventilation channels and optional smart-sensor temperature monitoring for main busbar connections, reducing the risk of thermal runaway.
Corrosion-Resistant Al-Zn Frame: The cabinet structure utilizes 2.0mm Al-Zn (Aluminum-Zinc) coated steel, providing superior mechanical strength and a lifespan of 30+ years in industrial environments without the need for repainting.

Global Shipping Standards: Shipped in reinforced, sea-worthy wooden crates with moisture-barrier vacuum packaging to ensure arrival in perfect condition.
Q: What is the difference between "Fixed" and "Withdrawable" units?
A: Fixed units are bolted in place and offer a lower-cost solution for stable loads. Withdrawable (Draw-out) units allow for rapid replacement of modules without powering down the entire board, making them ideal for critical facilities where downtime is not an option.
Q: Can you provide switchgear for outdoor installations?
A: While standard LV switchgear is for indoor use, we can provide specialized IP54 or IP55 "Outdoor Kiosks" or "Containerized Substations" specifically designed for outdoor environmental protection.
Q: Does your switchgear support remote tripping?
A: Yes. By utilizing motorized operating mechanisms and shunt trips within the circuit breakers, the switchgear can be fully integrated into your SCADA or Building Management System (BMS).
