Client: A Philippine airport electrical construction contractor
Project Name: Clark International Airport (CRK) New Passenger Terminal Building Expansion, Pampanga, Philippines
Project Commencement Date: December 2017
Project Completion Date: October 2020
Project Status: Completed
Project Details & Narrative:
Industry Context — Airport Terminal Electrical Infrastructure
The Clark International Airport expansion was a landmark infrastructure project under the Philippine government’s Build, Build, Build program — the country’s first hybrid public-private partnership (PPP) model. The project delivered a 110,000-square-meter, four-level passenger terminal with 18 boarding bridges, designed to handle 8 million passengers annually and decongest Manila’s Ninoy Aquino International Airport.
Airport terminals are among the most electrically demanding building types. A modern airport terminal of this scale requires:
- Main power distribution: Multiple transformers feeding a complex hierarchy of main distribution boards (MDB), sub-distribution boards (SDB), and final branch circuits
- Lighting systems: High-bay lighting for the apron and forecourt, architectural lighting for departures and arrivals halls, emergency and pathway lighting
- Baggage handling systems (BHS): Conveyor motors, sorting systems, and scanning equipment requiring dedicated feeders
- HVAC systems: Large-scale air handling units, chillers, and ventilation fans
- Passenger facilities: Boarding bridges, ground power units, visual docking guidance systems
- Security and IT: Access control, surveillance, flight information display systems (FIDS), and communications infrastructure
Every circuit must meet stringent fire safety and reliability standards — a cable failure in an airport terminal can disrupt thousands of passengers and multiple airlines simultaneously.
The Project
The EPC contractor responsible for the terminal’s electrical systems needed a cable supplier capable of delivering both high-capacity power feeders and general-purpose building wire in large quantities, with complete certification documentation and strict delivery scheduling to match the construction timeline.
The terminal’s electrical design specified:
- YJV 0.6/1kV power cables for all main and sub-distribution feeders — from the utility transformer through the main switchgear to sub-distribution boards throughout the four-level building
- THHN building wire for all branch circuits — lighting, outlets, equipment connections, and general power distribution to terminal fixtures
Cable Challenges
| Airport Terminal Challenge | Cable Requirement | JZD Solution |
|---|---|---|
| High-current main feeders from transformer | Large conductor, high insulation integrity | YJV 4×240mm² with PVC insulation rated 70°C |
| Long feeder runs across four levels | Voltage drop management, durable sheath | YJV with robust PVC outer sheath for conduit and cable tray |
| Branch circuits throughout 110,000 m² building | Easy-pull, durable, nylon-jacketed wire | THHN with nylon jacket for smooth conduit pulling |
| Fire safety in occupied public building | Flame-retardant construction | All cables IEC 60332-1 compliant |
| Strict construction deadline (completed 2020) | On-time delivery in phased shipments | JZD scheduled production and shipping to match site milestones |
| Large volume (38,000+ meters) | Manufacturing capacity and QC consistency | JZD’s Shenzhen factory with batch traceability and ISO 9001 QMS |
The Qualification Process
The EPC contractor’s evaluation included:
- YJV Insulation Integrity: Verification of PVC compound quality, conductor resistance, and insulation thickness per GB/T 12706 standards
- THHN UL 83 Compliance: Full documentation package with UL file numbers, confirming nylon jacket construction and 90°C rating
- Batch Sample Testing: Conductor resistance, insulation resistance, and spark testing on production samples
- Production Capacity Audit: Factory visit to confirm JZD’s ability to manufacture and deliver 38,000+ meters within the project timeline
How JZD Won
JZD Cable was selected because:
- Dual-Product Single Source: JZD could supply both YJV power cables (for feeders) and THHN building wire (for branch circuits) from one factory — eliminating the need to coordinate two separate suppliers, reducing procurement complexity and logistics costs
- Proven Export Track Record: JZD had prior experience supplying cable to Philippine construction projects, with established logistics channels and understanding of local import procedures
- Phased Delivery Capability: The terminal construction followed a strict schedule across multiple levels and zones. JZD arranged production and shipping in phases — delivering YJV main feeders first for the primary distribution infrastructure, followed by THHN branch wire as fit-out progressed
- Competitive Pricing with Complete Documentation: JZD’s quotation included full certification packages (GB/T test reports for YJV, UL documentation for THHN) at a price point that undercut multi-supplier sourcing
Installation & Performance
The cables were installed across the terminal’s four levels:
- Level 1 (Apron): YJV feeders powered the baggage handling system, ground support equipment, and boarding bridge connections
- Level 2 (Arrivals): YJV sub-feeders and THHN branch wire served immigration counters, baggage reclaim, and transfer corridors
- Level 3 (Departures): The largest consumer of THHN — check-in counters, security screening, emigration, retail spaces, and gate lounges
- Level 4 (Mezzanine): THHN powered food and beverage areas and CIP (Commercially Important Person) lounges
The terminal was completed in October 2020 and began operations in May 2022, with a grand opening ceremony presided over by Philippine President Ferdinand Marcos Jr. in September 2022. The electrical systems commissioned without issues, and the terminal has been operating at full capacity since.
Project Highlights:
- 110,000 m² terminal building fully cabled with JZD products
- 38,000+ meters of YJV and THHN supplied in phased deliveries
- Dual-product single-source procurement reduced total cable cost by an estimated 12% compared to multi-supplier sourcing
- All certification documentation accepted on first submission — zero rejection or re-testing
- Terminal operational since May 2022, electrical systems performing reliably under continuous 24/7 airport operations
