Project Name: Astana Light Rail Transit (LRT) – Depot
Product Scope: Hot-Dip Galvanized Cable Trays, Flexible Metal Conduits
Project Status: In Progress | Delivery Year: 2025
Client/Owner: Astana LRT
EPC Contractor/Procurement: China Railway Construction (CRCC)
Supplier: Burkaf
The Astana Light Rail Transit (LRT) is the first urban rail transit system in Kazakhstan's capital, Astana (now known as Nur-Sultan), representing a major milestone in the country's transportation infrastructure modernization. The LRT line connects major transportation hubs, commercial districts, and residential areas. Once completed, it will significantly alleviate urban traffic pressure and serve the daily commuting needs of the capital's residents. The depot, as a core supporting facility of the LRT system, handles critical functions including train parking, inspection, and maintenance.
Burkaf partnered with China Railway Construction Corporation (CRCC) to provide hot-dip galvanized cable trays and flexible metal conduits for the depot. The products need to adapt to the temperature fluctuations and seismic requirements of Kazakhstan's continental climate.
Extreme Temperature Fluctuations of Continental Climate: Astana is the second coldest capital in the world, with winter temperatures dropping as low as -40°C to -50°C and summer temperatures exceeding 30°C, resulting in enormous annual temperature variations. Products must maintain stable mechanical performance and dimensional accuracy under both extreme low and high temperatures.
Seismic Requirements for Rail Transit: Parts of Kazakhstan are located in seismic zones. As critical transportation infrastructure, the LRT must meet strict seismic design standards.
Special Operating Conditions of the Depot: The depot experiences frequent train movements, generating vibration, impact, and other dynamic loads, demanding high stability and durability from the cable tray and support system.
Installation and Maintenance Under Extreme Cold Conditions: Extreme low temperatures present challenges for on-site construction and later maintenance. Products must have good low-temperature toughness and ease of installation.
Coordination with China Railway Construction's High Standards: As one of the world's largest rail transit engineering EPC contractors, CRCC imposes strict requirements on supplier technical standards, quality management, and delivery systems.
Burkaf is providing hot-dip galvanized cable trays and flexible metal conduits for the depot of this project, fully meeting the high standards of the Astana LRT under extreme climate and seismic requirements.
1. Hot-Dip Galvanized Cable Trays: Excellent Corrosion and Weather Resistance
Hot-dip galvanized cable trays feature an immersion galvanizing process, with zinc layer thickness and adhesion far exceeding ordinary electro-galvanized products, offering excellent corrosion resistance. Under Astana's harsh cold and extreme temperature fluctuation conditions, they maintain structural integrity and electrical continuity over the long term, ensuring full lifecycle reliability of the cable routing system.
2. Low-Temperature Design: Adapting to Extreme Cold Climate
Burkaf products feature low-temperature-resistant material design, maintaining good mechanical performance under extreme low-temperature conditions of -40°C and below without embrittlement, cracking, or deformation. Material selection fully considers low-temperature impact toughness, ensuring long-term reliable operation during Astana's winters.
3. Flexible Metal Conduits: Cold-Resistant End-Point Protection
Burkaf flexible metal conduits utilize low-temperature-resistant materials, maintaining good flexibility under harsh cold conditions for easy on-site installation and later maintenance. Their metal construction also provides good mechanical protection, safeguarding cables within the depot from physical damage.
4. Adaptability to Severe Temperature Fluctuations
Products feature good thermal stability and resistance to thermal expansion and contraction, maintaining dimensional stability and connection reliability under extreme conditions with annual temperature variations exceeding 70°C.
5. Vibration-Resistant Design: Adapting to Dynamic Loads in the Depot
To address the vibration and impact generated by train movements within the depot, Burkaf trays and connectors feature high-strength designs and anti-loosening measures, ensuring they remain secure and undeformed during long-term operation.
6. Meeting China Railway Construction's Strict Standards
Burkaf products have successfully passed technical reviews and quality inspections by CRCC, with complete product documentation, test reports, and quality traceability documents provided, demonstrating the capability to serve a world-class rail transit engineering EPC contractor.
7. Delivery Capability Synchronized with Project Schedule
As an ongoing project, Burkaf is delivering products in batches according to schedule, continuously coordinating with CRCC's construction timeline to ensure the Astana LRT depot construction progresses as planned.
Burkaf hot-dip galvanized cable trays and flexible metal conduits have been delivered to the Astana LRT project site according to schedule.
Products have successfully passed quality inspections and on-site acceptance by CRCC.
Burkaf has become one of the cable tray suppliers participating in Kazakhstan's first urban rail transit system.
Participation in the Astana LRT project marks Burkaf's successful entry into the rail transit sector in Central Asia, a high-barrier field. The combined solution of hot-dip galvanized cable trays and cold-resistant flexible metal conduits fully satisfies cable management requirements under extreme continental climate and seismic demands. Collaboration with CRCC further enhances Burkaf's brand credibility in large-scale rail transit projects.
