Project Details & Narrative:
The Data Center Power Hierarchy
Data center power flows from the utility grid through multiple transformation and distribution stages before reaching individual server racks. The main feeder stage — between MV/LV transformers and main switchgear, and between switchgear and Power Distribution Units (PDUs) — carries the highest currents and demands the largest cable cross-sections.
A single hyperscale data hall can require over 1000 meters of large cross-section power cable. The main feeder layer is the circulatory system of the data center — a failure here cascades to everything downstream.
The Project
In 2026, JZD Cable supplied main feeder cables for a data center in Philippine. The facility design included 10 number data halls, redundant utility feeds, N+1 backup generation, and UPS systems with battery storage.
The main feeder scope covered:
| Power Path | Cable | Cross-Section | Quantity |
|---|---|---|---|
| Transformer → Main LV Switchgear | YJV Single Core | 1x300mm², 1x400mm² | [待确认] m |
| Main Switchgear → UPS Input | YJV Multi-Core | 3x150mm²+1x70mm² | [待确认] m |
| UPS Output → PDU | YJV/YJV22 | 4x185mm²+1x95mm² | [待确认] m |
| Generator → ATS | YJV22 Armored | 4x240mm² | [待确认] m |
| Underground duct banks | YJV22 Armored | 3x120mm² | [待确认] m |
Why Large Cross-Section YJV?
Data center feeders run high currents continuously. Undersized cables create voltage drop that wastes energy as heat, reduces UPS efficiency, and can cause equipment malfunction. YJV cables with XLPE (cross-linked polyethylene) insulation provide:
- High ampacity: 90°C continuous operating temperature allows higher current per cross-section vs. PVC-insulated cables
- Low conductor resistance: 99.95%+ purity copper minimizes I²R losses
- Thermal stability: Short-circuit rating of 250°C (max 5s) provides safety margin for fault conditions
- Long service life: XLPE insulation resists thermal aging far better than PVC, critical for 25+ year data center lifespan
How JZD Won the Contract
- Large-Scale Production Capacity: JZD’s Shenzhen factory demonstrated capability to manufacture [待确认 — km] of large cross-section cable within the project timeline.
- Consistent Quality at Scale: The client’s engineering team audited JZD’s production process, verifying that quality remains consistent from the first reel to the last — critical when hundreds of reels must perform identically.
- Conductor Resistance Verification: Sample testing confirmed conductor resistance values well within IEC 60228 Class 2 limits — a key metric for data center energy efficiency.
- Armored Cable Expertise: The underground duct bank sections required YJV22 steel-tape armored cable. JZD’s armored cable production line had proven capability for this specification.
- Competitive Bulk Pricing: Direct factory supply on this scale delivered measurable project cost savings.
Delivery & Documentation
The order was split into 3 phases aligned with construction sequencing:
- Phase 1: Transformer to switchgear feeders
- Phase 2: Switchgear to UPS and PDU feeders
- Phase 3: Generator and underground circuits
Each shipment included full documentation: IEC 60502 compliance certificates, conductor resistance test data, insulation integrity test reports, and reel-by-reel traceability records.
Outcome
- All main feeder cables installed and tested without defects
- Insulation resistance testing passed on all circuits
- Data center achieved Tier certification and went live on schedule
- Client added JZD to approved vendor list for future data center projects
