Transforming Rail Safety: How We Shielded a Pantograph Camera in a 25kV Extreme Environment
Project Overview
When a European client partnered with Turkey's TÜRASAŞ on the 225 km/h National EMU Project, they faced a critical challenge: ensuring reliable pantograph camera performance in a punishing 25kV AC environment. Exposed to high-voltage lines, their existing camera suffered from electromagnetic interference (EMI), physical vulnerabilities, and lens fogging—threatening safety and operational uptime. That's when they turned to TIENUO INTELLIGENT, a leader in train onboard security with over two decades of expertise. Our solution? The Pantograph Guardian 25kV Camera Enclosure—a breakthrough in rail surveillance resilience.
The Challenge
Operating at 225 km/h in a high-voltage setting, the pantograph camera was a linchpin for real-time monitoring—but it was faltering:
EMI Disruptions: High-voltage lines scrambled footage and functionality.
Physical Exposure: A fallen overhead line risked catastrophic damage.
Visibility Issues: Temperature swings fogged the lens, obscuring critical data.
The client needed a fix that wouldn't just patch the problem but set a new standard for durability and performance.
Our Solution: The Pantograph Guardian
Drawing on our 24-year legacy in visual behavior recognition and rail security, we engineered the Pantograph Guardian—a fortress for pantograph cameras. Designed to exceed industry standards (DIN EN 50124, DIN EN 50122-1, EN45545, EN61373), this enclosure delivers:
25kV Insulation: Over 10 MΩ impedance shields against electrical leaks and EMI.
Rugged Protection: IP65-rated, corrosion-resistant (C4-grade), and vibration-proof (1.2g).
Extreme Durability: Operates from -40°C to +70°C with 5g seismic resistance.
Uninterrupted Clarity: Heated glass eliminates fogging for flawless visuals.
Safety First: Non-flammable materials ensure compliance and reliability.
Components like the metal hood, sealed connectors, supplementary lighting, and heated lens glass work in harmony to protect and enhance camera performance, even under the harshest conditions.
The Results
Deployed on the TÜRASAŞ National EMU Project, the Pantograph Guardian transformed the game:
Zero Failures: Flawless operation in full 25kV testing.
Enhanced Safety: Neutralized risks from overhead line disruptions.
Efficiency Boost: Easy-access design cut maintenance time by 50%.
The client's feedback says it all: “This solution didn't just meet our needs—it redefined what we thought was possible.”
Why It Matters
This isn't just a win for one project—it's a blueprint for rail innovation worldwide. The Pantograph Guardian is purpose-built for high-speed trains, pantograph monitoring, and extreme-voltage environments, making it an ideal fit for rail manufacturers, system integrators, and security providers. With certifications like IRIS, ISO9001, and CRCC, and a proven track record across China's railway system and global markets, TIENUO INTELLIGENT continues to lead the charge in rail safety solutions.
