Heavy-Duty C-Profile Framework & Rigid Modular Design
The core structural stability of this low voltage electrical switchgear cabinet relies on an advanced framework cold-formed from high-strength C-profile steel sections. Engineered with a global standardized mounting hole arrangement spaced at E=25mm increments, this architecture provides exceptional rigidity while allowing internal component restructuring without field re-drilling. The framework and internal partitions are zinc-galvanized and passivated, delivering robust mechanical load performance and long-term anti-corrosion protection in high-humidity or industrial coastal zones.
High-Capacity Busbar Integration Up to 6300A
Engineered for major power substations and heavy industrial plants, this drawout switchboard cabinet platform supports main horizontal busbar currents up to 6300A, operating under a 690V insulation system. It offers supreme fault ride-through capabilities, handling peak short-circuit current stresses up to 176 kA. The main busbar system is situated in a dedicated back-compartment, separate from the front functional units and cable tracking fields, which greatly dampens internal arc risks and provides operators with safety peace-of-mind.
Precision Multi-Scale Drawer Modularization (8E/4 to 24E)
To optimize Motor Control Center (MCC) space density, the system divides its 1800mm active functional height using an 8E (200mm) base block matrix. It supports 5 distinct drawout unit models: 8E/4, 8E/2, 8E, 16E, and 24E. Up to 36 independent 8E/4 small feeder or motor starter modules can be stacked into a single cabinet enclosure. Every drawout unit is fitted with a specialized mechanical safety lock sequence, ensuring explicit isolation during physical unit swapping or electrical line maintenance testing.
Rigid Environmental Seal & Safety Isolation Options
Meeting diverse international construction and environmental safety codes, this heavy-duty modular switchboard can be customized with IP30, IP40, or dust-proof IP54 ratings to protect internal breakers from hostile workshop pollutants. It operates at full performance up to altitudes of 2000m, dealing with ambient ambient thresholds from -5°C up to +40°C. Internal flame-retardant insulating barriers effectively contain potential localized thermal hazards, ensuring neighboring control blocks continue to run without disturbance.
