University Teaching Building Power Distribution Project, Beijing
Confidential
This project involved the new construction of a university teaching building in Beijing, where Yanghua flexible busbars were extensively deployed across multiple power distribution tiers. The electrical system design required power transmission from low-voltage distribution cabinets to floor-level power boxes, and further from power boxes to air-conditioning equipment throughout the building. Flexible busbar specifications covered a wide range from 630A, 800A, and 1000A to 1250A, providing graded current capacity matching the diverse load requirements at each distribution level. All busbar products were installed within the original narrow bridge trays designed into the building structure. The compact dimensions of the flexible busbars allowed for easy insertion and routing through these constrained bridge spaces without requiring structural modifications or expanded tray dimensions.
Project Background & Challenges
A new university teaching building required a comprehensive power distribution system spanning four current ratings (630A to 1250A) across multiple floors and equipment types, all constrained within the building's original narrow bridge tray dimensions with no room for structural expansion.
- Multi-tier power distribution required spanning from main low-voltage cabinets through floor boxes to terminal HVAC equipment across a large building footprint
- Four distinct current ratings (630A, 800A, 1000A, 1250A) needed to be accommodated without compromising the unified installation methodology
- Original bridge trays were dimensionally narrow and could not be modified or expanded due to structural design constraints
- Installation needed to proceed efficiently across multiple floors with consistent product handling and connection procedures
Solution
Yanghua supplied flexible busbars in 630A, 800A, 1000A, and 1250A specifications that fit directly into the existing narrow bridge trays. The graded current ratings enabled optimized power delivery from main LV cabinets through floor-level distribution to end-use air-conditioning equipment.
- Provided a complete flexible busbar product range from 630A to 1250A, enabling graded power distribution matched precisely to each circuit's load profile
- Leveraged the inherently compact cross-section of flexible busbars to install all conductors within the original narrow bridge trays without structural modification
- Implemented a unified installation methodology across all four current ratings, streamlining onsite work and reducing training requirements for installation teams
- Enabled direct connections from LV cabinets to power boxes and from power boxes to air-conditioning units using the same flexible busbar product family
