Overview
The Chengdu Metro Line 5 in China required surge protectors for its wireless, video surveillance, broadcasting, PIS, clock and power distribution systems to ensure the uninterrupted operation of the rail transit system.
Challenge
The project faced several challenges in implementing surge protection across the metro systems:
● High Passenger Traffic: The systems required a high level of stability to ensure smooth operations.
● System Complexity: Surge protectors were needed for wireless, video surveillance, broadcasting, PIS, clock, and power distribution systems, each with specific protection requirements.
● Maintenance Concerns: The client worried about future maintenance costs due to the busy operation of the metro system.
Solution
The integrator partner had previously used Ourten surge protectors in other projects, building confidence in recommending them to the metro operator.
● Product Validation: Surge protection professionals conducted simulated discharge tests to ensure effectiveness.
● Certified Protection: Ourten surge protectors achieved type certification, diverting induced overvoltage to the ground to protect communication equipment.
● Easy Maintenance: The products are equipped with remote signaling terminals, allowing users to directly monitor their operational status.
Result
Using 700 units Ourten surge protectors, the client reduced costs by $28,000 and ensured comprehensive protection across six subsystems. The solution enhanced system security, reduced costs by 13%, and eased maintenance concerns.
