Key Product Features
1.Flexible Modular Design
C-profile assembled frame offers high structural strength. All structural members are zinc-plated or made of aluminum-zinc coated steel plate for corrosion resistance.
Modular design (E=25mm). Component and compartment sizes vary according to the modulus, allowing flexible configuration, easy expansion, and modification.
Withdrawable units have Connect, Test, Disconnect, and Withdrawn positions with mechanical interlocking, ensuring operational safety and reliability.
Compact structure, with up to 36 circuits per cabinet, maximizing space utilization.
2.Exceptional Safety and Reliability
Passed multiple stringent tests, including seismic resistance (seismic intensity level 9), internal arc testing (100kA/0.5s), salt spray test (96 hours), and high-altitude test (4000 meters), adapting to various harsh environments.
Completely separated by steel plates or high-strength flame-retardant plastic functional boards between compartments, effectively preventing fault arc propagation and ensuring safety for equipment and personnel.
3.Provides high protection degree (IP54)
against dust and water, suitable for complex environments.
4.Smart Digital Integration (Optional)
Can integrate temperature sensors for monitoring critical connections and smart electrical devices for current and voltage monitoring.
Supports multiple communication protocols (e.g., Modbus RTU/TCP, Profibus DP, Profinet, IEC 61850) for easy integration into plant monitoring and control systems.
Enables predictive maintenance and energy efficiency management through cloud platforms, reducing unplanned downtime and optimizing operational costs.
5.Global Applicability and High Adaptability
Complies with multiple international standards such as IEC, GB, UL, AS, meeting global market access requirements.
Offers various cable entry/exit options (top-top, top-bottom, bottom-top, bottom-bottom), adapting to different on-site wiring needs.
Wide operating temperature range (-25℃ to +55℃, up to +70℃ for short periods). Built-in temperature control devices ensure stable operation at high altitudes or in extreme climates.
6.Quality Manufacturing and Easy Maintenance
Enclosure finished with epoxy resin powder electrostatic spraying (Standard color RAL7035), providing corrosion and impact resistance.
Functional units are easy to replace and maintain. High interchangeability of drawers significantly reduces downtime for maintenance.
Front operation and maintenance, allowing rear-to-wall installation and saving space.
