The Challenge: Powering Infrastructure in Extreme Conditions
Environmental and Technical Hurdles
The Uyuni Airport expansion presented electrical contractors with a unique combination of challenges that demanded more than standard cable solutions.
At 3,700 meters above sea level, the airport faces intense UV exposure, temperature swings from -15°C to 25°C, and salt-laden winds from the nearby Salar de Uyuni—the world's largest salt flat. These extreme conditions accelerate cable degradation and require materials with superior weather resistance and long-term reliability.
As an IDB-financed project, the airport required materials meeting strict international standards. The Bolivian market has historically struggled with counterfeit electrical products, making authentic UL certification verification critical for project approval. Any material non-compliance could result in project delays or acceptance failures.
Bolivia's landlocked position means all materials must transit through Chilean or Peruvian ports, then traverse over 750 kilometers of Andean terrain to reach Uyuni. Any supply delays would cascade through an already tight construction schedule targeting 2026 completion.
The expanded facility also required seamless integration of medium voltage distribution, low-voltage power systems, control circuits for runway lighting, baggage handling, HVAC, and fire safety systems. All these systems demanded different cable specifications with guaranteed compatibility.
The Client's Core Concerns
The project electrical team needed a supplier who could guarantee three non-negotiable conditions. First, authentic UL certification with complete documentation traceability to verify the genuine source of every cable. Second, proven experience in aviation or similar critical infrastructure demonstrating understanding of project complexity. Third, reliable delivery timelines that wouldn't jeopardize the construction schedule due to supply chain issues.
Our Solution: Engineered Cable Systems for Mission-Critical Applications
We developed a tiered cable supply strategy that matched specific products to each system's operational demands and environmental exposure, ensuring every application scenario received the most suitable cable solution.
Medium Voltage Distribution Solution
For the airport's primary power feed from the government-funded electrical substation, we supplied two key products. MV90 cables with 5kV rating served standard distribution runs. MV105 cables with 15kV rating handled high-capacity feeders while providing capacity for future expansion.
Both cables feature XLPE insulation specifically selected for thermal stability in Uyuni's temperature extremes and moisture resistance against high-altitude condensation. The XLPE material maintains stable insulation performance through dramatic temperature variations while effectively resisting the condensation erosion common at high elevations.
Terminal Building Power Distribution
The terminal's internal electrical distribution required two distinct cable strategies. For standard circuits including lighting, receptacles, and general power distribution, we selected THHN/THWN-2 nylon-jacketed building wire ranging from 14 AWG to 4/0 AWG. The dual-rated THHN/THWN-2 construction provides the wet-location rating necessary for Uyuni's occasional precipitation and humidity variations, ensuring safe operation under changing climate conditions.
For high-demand feeders including main electrical room connections, HVAC units, and baggage handling systems, we specified XHHW-2 insulated conductors. The flagship specification in this category was 350 kcmil XHHW-2 industrial cable for primary feeder connections.
Why 350 kcmil XHHW-2 Industrial Cable Was the Superior Choice
The project engineers initially considered standard THHN cables for these high-capacity feeders. Through our technical consultation, detailed comparison demonstrated why 350 kcmil XHHW-2 industrial cable was the optimal selection.
In terms of temperature rating, 350 kcmil XHHW-2 industrial cable achieves 90°C in wet conditions compared to only 75°C for standard THHN. In Uyuni's high-altitude environment, the combination of intense solar radiation heating and high electrical loads makes this additional 15-degree temperature margin critical for safe operation.
Regarding insulation materials, 350 kcmil XHHW-2 industrial cable uses XLPE cross-linked polyethylene, which offers superior chemical resistance compared to THHN's PVC polyvinyl chloride. This effectively resists the corrosive salt dust prevalent in the Uyuni region. XLPE material also maintains flexibility in low temperatures, while PVC becomes brittle and prone to cracking in cold conditions.

For installation convenience, 350 kcmil XHHW-2 industrial cable features a smaller diameter, which significantly simplifies pulling operations in crowded terminal ceiling spaces, reducing installation difficulty and labor costs. The reduced outer diameter also means more cables can be routed through the same conduit size, improving design flexibility.
In terms of service life, 350 kcmil XHHW-2 industrial cable demonstrates excellent performance under UV exposure, which is particularly important for Uyuni's intense solar radiation environment. This ensures the cable maintains stable electrical performance over decades of service.
Control and Instrumentation System Cables
For the airport's operational control systems, we provided two specialized cable solutions. TC-ER tray cable in multi-conductor configurations up to 12 AWG served runway lighting controls, security systems, and fire alarm networks. The TC-ER rating allows exposed runs between equipment rooms without additional conduit protection, significantly reducing installation complexity and material costs while shortening construction time.
MC metal-clad cables were deployed for circuits running through high-traffic maintenance corridors and areas requiring mechanical protection. The aluminum armor provides reliable damage protection against accidental impacts during construction and mechanical wear during long-term operation, while maintaining sufficient flexibility for convenient field installation.
Specialized Application Cables
In the control and communications domain, we selected PLTC power-limited tray cable and ITC instrumentation tray cable, specifically for low-voltage control signals and data transmission between airport systems. These cables feature excellent shielding performance and signal integrity, ensuring accurate transmission of critical control commands.
For underground distribution applications including perimeter lighting and ground-mounted signage, we supplied UF-B underground feeder cables in 10/2 and 8/2 configurations. The direct burial rating of UF-B eliminates conduit requirements in landscape areas, which not only reduces material costs but also significantly decreases excavation and backfill work, shortening installation time.
The landscape lighting system employed specialized outdoor-rated cables with enhanced UV and moisture resistance for terminal exterior lighting and parking area illumination. The jacket materials of these cables are specially formulated to withstand Uyuni's intense solar radiation and occasional precipitation erosion over the long term.
Safety Assurance: Certification as the Project Foundation
UL Certification Portfolio
Every cable we supplied for this project carried authentic UL certification with complete traceability documentation. THHN/THWN-2 building wire complies with UL 83 standards for general power distribution. XHHW-2 cables meet UL 44 standards, specifically targeting high-temperature and wet-location applications. MV90 and MV105 medium voltage cables comply with UL 1072 standards, ensuring safe and reliable power distribution. TC-ER tray cables meet UL 1277 standards, validating their safety for exposed run installations. MC metal-clad cables comply with UL 1569 standards, guaranteeing mechanical protection reliability. UF-B underground feeders meet UL 719 standards for direct burial application safety. PLTC and ITC power-limited cables comply with UL 13 standards for control and instrumentation systems.
This comprehensive certification coverage ensures the entire electrical installation passes inspection without complications. For government-funded projects subject to IDB oversight and international auditing, this certification integrity provides essential compliance assurance.

Complete chain-of-custody documentation from manufacturing to site delivery ensured every cable's source was traceable, eliminating counterfeit product risks.
Execution Phase: On-Time Delivery in a Challenging Environment
Logistics Strategy
Deeply understanding Bolivia's landlocked logistics challenges, we implemented a carefully designed multi-modal delivery strategy. First, cables were shipped by sea to the Port of Arica, Chile, which serves as Bolivia's primary maritime gateway for imports and exports. Then our specialized cross-border coordination team handled customs procedures between Chile and Bolivia, ensuring complete documentation and smooth clearance. Finally, experienced overland transport partners delivered the goods to the Uyuni construction site across 750+ kilometers of Andean highway networks.
Rapid Response Capability
During project execution, design modifications required additional 350 kcmil XHHW-2 industrial cable for an expanded baggage handling system. Thanks to our regional inventory positioning capabilities, we completed emergency supply within 14 days, preventing schedule delays and maintaining the project's critical path. This response speed is particularly remarkable in remote high-altitude regions, demonstrating the resilience and efficiency of our supply chain.
Extreme Condition Packaging
All cables received special packaging treatment before shipment to address various challenges during transport. Moisture-barrier packaging effectively prevents condensation issues that might arise from high-altitude pressure variations. Reinforced wooden drum designs withstand the bumps and vibrations of mountain road transport. The overall packaging also resists dust and salt exposure during transit, ensuring cables arrive at the site in perfect factory condition.
