Structure Function
Frame support structure: High-strength metal (galvanized steel plate or 304/316 stainless steel) frame is used to provide stable mechanical support, ensuring that internal components are firmly installed and resistant to vibration and impact.
Modular unit partitioning: The interior is divided into functional areas (such as incoming line room, outgoing line room, instrument room). The modular design facilitates maintenance and expansion while avoiding electrical interference.
Protection and insulation system: Equipped with insulating partitions, protective covers and flame-retardant materials to prevent electric shock and short circuit, with protection level above IP54.
Heat dissipation and ventilation design: built-in heat dissipation holes, fans or natural convection channels, and some high-end cabinets are equipped with temperature control devices to ensure that components operate at an appropriate temperature.
Standardized wiring and identification: Provide clear wire ducts, terminal blocks and cable management space, and mark electrical parameters and circuit numbers to facilitate installation, maintenance and troubleshooting.
Safety interlock mechanism: Equipped with mechanical/electrical interlocking devices (such as interlocking of circuit breaker operating handle and cabinet door) to prevent live operation and ensure personnel safety.
