Corrosion Protection System for New Hudson Yards
Challenge: The 28-acre Hudson Yards real estate development project in New York City is being constructed above existing rail yards and subway tunnels. The Long Island Railroad (LIRR) is a key partner in the multi-year project, scheduled for completion in 2025. In order to build in maximum structural integrity to support the massive platform-based design, project engineers specified a system that would actually resist corrosion in the buildings’ infrastructure.
Solution: LIRR reached out to Comtran Cable, an approved supplier in rail transit telecommunication cable. With expertise in high performance low-smoke, zero halogen transit cable, Comtran fast-tracked engineering on the new product. Working in close collaboration with UL, they were able to deliver an approved prototype in 90 days: a low voltage, 4-conductor, individually shielded cable. The cable provides control and monitoring functions to the unique anti-corrosion system. The new cable is packaged in 1,000′ lengths to allow for installation of system components at set intervals.
Result: The breakthrough system works by pulsing cathodic electron charges through the cable at regular intervals. These charges fill the atomic valences that normally would attract oxygen, inhibiting formation of rust. The system protects the integrity of steel in below grade construction – a must for a project of this scale. The new HUB-Link® 4-conductor individually shielded cable is available in 12 AWG and smaller.
