Yanghua Cable Customer Case: APAC Data Center Flexible Busbar Installation
Flexible busbars from Yanghua Cable are a proven solution for APAC data center power distribution, offering space savings and simplified installation compared to traditional cables or rigid busways. This case study details how a hyperscale data center in Singapore used Yanghua’s flexible busbar to overcome tight space constraints, reduce installation time by 40%, and maintain high reliability. [K1]
Application Scenario
A leading APAC hyperscale data center operator faced challenges with conventional cable tray and rigid busbar installations in their new Singapore facility. The client required a power distribution solution that could [K1]:
- Fit within 300mm vertical cable management spaces between server racks.
- Reduce installation labor by 35% compared to rigid busbars.
- Provide flexible routing to avoid existing structural columns and cooling pipes.
- Support 250A to 800A ratings for different power distribution requirements.
Yanghua’s flexible busbar was selected after a three-month technical evaluation process [K1].
Engineering Decision Criteria
The evaluation team prioritized the following factors:
| Criterion | Requirement | Yanghua Flexible Busbar Performance |
|---|---|---|
| Bending radius | ≤ 100mm for tight corners | 75mm minimum bending radius [K1] |
| Current rating | 250A-800A | Meets ratings per IEC 61439-1 [K1] |
| Installation time | ≤ 2 hours per 10m run | 1.2 hours achieved [K1] |
| Fire resistance | IET wiring regulations compliant | Compliant with BS 476 Part 7 [K1] |
| Space utilization | ≤ 300mm width | 280mm for 630A rated solution [K1] |
The busbar’s key advantages were its ability to be bent on-site without special tooling and its compact cross-section that fit into standard cable management channels [K1].
Suitable and Not Suitable Cases
Suitable for [K1]:
- Hyperscale and colocation data centers with high-density rack layouts.
- Retrofit or expansion projects where existing cable trays cannot be modified.
- Installations requiring frequent re-routing or flexible topology changes.
- APAC projects requiring compliance with local electrical codes.
Not suitable for [K1]:
- Outdoor installations without additional weatherproofing (busbar is IP42 rated indoors).
- High-vibration environments without specific damping measures.
- Projects requiring direct burial or submersion in water.
- Custom lengths less than 2 meters (minimum production length applies).
Procurement Notes
Based on the case experience, buyers should [K1]:
- Specify the exact routing path – While flexible, the busbar has minimum and maximum bend radius constraints. Provide CAD drawings for pre-fabrication.
- Request thermal imaging reports – Yanghua can provide factory thermal test data for specific configurations.
- Order connectors and accessories – Ensure matching end-fittings, T-junctions, and support brackets are included.
- Allow 4-6 weeks lead time – For custom lengths and configurations from Yanghua’s production schedule.
- Verify local certifications – While IEC 61439-1 compliant, check if additional local testing is required.
Frequently Asked Questions
Q: How do flexible busbars compare to traditional cables for data center power distribution? A: Flexible busbars offer 50% space savings, faster installation, and better thermal performance, but require higher upfront cost. For this APAC project, the space savings justified the investment. [K1]
Q: Can this busbar be installed during live data center operations? A: Yes, with proper isolation. The busbar is designed for maintenance without full system shutdown, but always follow local safety regulations. The case study showed minimal downtime during retrofit. [K1]
Q: What is the service life of Yanghua flexible busbars in data center environments? A: Yanghua specifies a 20-year life under normal operating conditions (0-40°C, humidity <85%). Actual performance depends on load cycles, but the installed system has shown no degradation after 2 years. [K1]
Q: Are there any specialized tools required for installation? A: No special tools needed for bending or cutting. Standard electrical hand tools suffice, which reduced labor costs by 25% in this case. [K1]
Q: How is the busbar grounded for safety? A: Each busbar section includes an integral earth conductor, and connectors maintain continuity. Ground bond resistance tests passed at <0.05 ohms. [K1]
