Cable systems
Cables offer an optimal solution for reducing the weight of bridges while enhancing their span, leading to material savings and a reduced environmental footprint. Additionally, their use contributes to shorter construction timelines.
Stay cable bridge
OVM280 Multi-strand Stay Cable System
The OVM280 Multi-stand Stay Cable System is designed to improve the performance of cable-stayed bridges, towers, and other infrastructure by incorporating optimizations to fatigue resistance, anchorage design, and corrosion protection. Based on the OVM250 steel strand cable, the OVM280 system introduces key enhancements that boost the durability and reliability of the entire structure.
Key Improvements Include:
- Increased Fatigue Resistance: The system can withstand higher fatigue stress, reaching 280 MPa, offering significantly improved longevity.
- Optimized Anchorage Design: The cable’s anchorage unit is engineered to enhance load distribution, ensuring more efficient performance.
- Enhanced Corrosion Protection: Multi-layered anti-corrosion technology ensures the system is protected, particularly in harsh marine environments.
Key Features
1. Superior Fatigue Resistance
The OVM280 cable is designed to handle higher fatigue stress (280 MPa), resulting in a fatigue life nearly 4 times longer than conventional cables with lower stress amplitudes. This makes it ideal for structures exposed to dynamic loads.
2. Optimized Anchorage and Load Distribution
The anchorage unit is optimized for better load distribution, ensuring the stability and performance of the system. These design improvements enhance the overall reliability and safety of the structure.
3. Advanced Anti-Corrosion Design
The OVM280 features a multi-layered anti-corrosion structure for the cable’s free section and anchorage unit, protecting it from environmental damage. The system also includes oil-based wax-filled anchor cavities to maintain water tightness and further prevent corrosion.
4. Marine Environment Suitability (Grade C5-M)
With its advanced corrosion protection, the OVM280 system is rated C5-M, making it suitable for harsh marine environments, including offshore and coastal projects.
5. Wind Resistance and Vibration Reduction
The OVM280 incorporates technologies to reduce wind-induced vibrations, improving stability and enhancing long-term performance.
6. Smart Integration
The system includes smart monitoring solutions to track the condition of the cables in real-time, optimizing maintenance and ensuring the structure remains in top condition.
7. Fire Prevention
Fire prevention technology is built into the system, enhancing safety in extreme conditions.
Applications
The OVM280 Multi-stand Stay Cable System is ideal for a variety of infrastructure projects, including:
- Cable-Stayed Bridges: Suitable for high-load, long-span bridges, providing strength, stability, and fatigue resistance.
- Towers and High-Rise Buildings: Used to support tall structures requiring reliable stay cables.
- Marine and Coastal Structures: Excellent protection against saltwater corrosion, ideal for offshore and coastal environments.
- Specialized Infrastructure: Applied in large roofs, stadiums, and unique structures needing precise load-bearing and enhanced durability.
