We have been deeply involved in the Shenzhen Metro project, delivering customized high-performance cabinet solutions tailored to its unique underground operating environment and complex engineering demands. These solutions effectively support the stable operation and intelligent upgrade of the entire rail transit system.
I. Project Background
Challenging Underground Conditions
Metro construction and operation present a series of extreme environmental challenges for equipment:
- High Humidity & Corrosion:
Underground ventilation is limited, with humidity exceeding 90% year-round, requiring outstanding anti-corrosion performance from all equipment. - Vibration & Electromagnetic Interference:
Frequent train operations generate continuous vibration and intense electromagnetic radiation, demanding enhanced structural strength and EMI shielding. - Fire Safety & Emergency Needs:
Enclosed and densely populated spaces necessitate flame-retardant equipment to ensure safe evacuation and effective emergency response in case of fire. - Complex Construction Environment:
Located in urban cores with dense above- and below-ground pipelines, metro construction involves extended timelines and frequent relocations, requiring highly compatible and reliable equipment.
II. Solution Highlights
✅ Advanced Anti-Corrosion Design for Humid Environments
Cabinets are made of hot-dip galvanized steel with salt-spray-resistant coating for superior rust and corrosion resistance.
Sealed structure prevents moisture intrusion, ensuring long-term stable performance.
✅ Multi-Level Seismic Protection for Operational Stability
Reinforced core structures validated through dynamic load testing.
Built-in shock-absorbing components mitigate vibrations from train movement.
✅ Enhanced Electromagnetic Shielding for Signal Integrity
Fully enclosed metallic structures with grounding and shielding layers effectively block external EMI.
Ensures stable operation of critical systems such as signaling and surveillance.
✅ Flame Retardancy & Heat Resistance for Safety Assurance
All cabinets and cable ducts meet EN 45545-2 / IEC 60332 flame-retardant standards.
Provides fire protection during emergencies, enabling fault isolation and timely rescue.
III. Project Outcomes
Through our participation in the Shenzhen Metro project, we have achieved:
- Custom delivery of communication and surveillance cabinets across multiple metro stations.
- Stable operation in harsh environments with significantly reduced maintenance workload.
- Long-term, strategic cooperation with the rail engineering teams.
This project has proven the long-term reliability and technical excellence of our cabinet systems in complex transit environments and marks our rail transit solution as ready for industrial-scale deployment.
IV. Expertise-Driven Foundations for Reliable Transit Equipment
With over 20 years of industry experience, we continuously innovate in cabinet structure design, protection technologies, and electromagnetic compatibility. We are equipped with:
- Advanced automated production lines
- Comprehensive quality inspection and factory testing processes
- A professional technical support team for on-site customization and service
Looking ahead, we will continue to cultivate the rail transit sector, focusing on the goals of “safety, efficiency, and intelligence” to deliver superior products and services that elevate Shenzhen and China’s urban rail transit systems to new benchmarks.
