Bolivia Lithium Mining Project

The Uyuni Lithium Industrialization Project is one of the most strategically important mining and industrial electrification projects in South America, located in Bolivia’s Uyuni salt flats, focusing on lithium extraction, processing, and battery material production, which requires a highly stable and efficient electrical infrastructure to support continuous heavy-duty operations.

Industry: Mining & Industrial Processing

Project Type: Power distribution, equipment connection, and industrial control system wiring

Construction Period: 2022 – 2025 (phased implementation)

Due to the harsh natural environment and high-load industrial processes, the project required a complete cable solution capable of handling high current loads, high temperatures, corrosive conditions, and long-distance installation challenges.

Client Requirements: High Ampacity, High Temperature Resistance

The client required a cable system that could meet both operational performance and international certification standards, with detailed specifications as follows:

Voltage Level: 600V – 1000V low-voltage industrial systems

Temperature Rating: 90°C (continuous operation), with higher tolerance for control systems

Installation Environment:

• Outdoor exposure (strong UV radiation)
• Underground and cable tray systems
• Humid and corrosive salt-lake conditions

Certification Requirements: UL standard compliance (UL83, UL44), partially aligned with IEC standards

Specific Ampacity Demands

Main power feeders: up to 380–430A (500 kcmil class)

Equipment supply circuits: 115–195A

Control systems: 20–40A

These requirements demanded not only high ampacity performance but also long-term durability under extreme environmental stress.

Project Challenges: Harsh Environment, Installation Complexity, and Cost Pressure

This project presented several critical challenges that are typical in large-scale mining electrification but particularly intensified in lithium processing environments:

1. Strong UV exposure and temperature fluctuations required cables with superior weather resistance
2. Oil, chemical exposure, and corrosive salt conditions demanded enhanced insulation materials
3. Long-distance cable routing and frequent bending increased installation difficulty
4. Moving equipment and cable tray systems required mechanical durability and flexibility
5. Strict UL compliance standards added complexity to product selection
6. Budget constraints required balancing high performance with cost efficiency

Cable Solution: Optimized Selection of XHHW, SIS, and TC-ER Cables

To address the above challenges, our team provided a targeted cable solution combining three core cable types, each selected based on specific functional requirements and installation conditions.

1. Main Power Distribution Solution

Cable Type: XHHW-2 copper conductor

Size: 500 kcmil / 350 kcmil / 4/0 AWG

Ampacity: up to 380–430A

500 kcmil XHHW-2 copper conductor cables ampacity for industrial power distribution were selected for their cross-linked polyethylene (XLPE) insulation, which provides excellent thermal resistance, moisture resistance, and long-term stability, making them significantly more reliable than standard PVC-insulated building wires in high-load and humid environments.

2. Industrial Control System Wiring

Cable Type: SIS (Switchboard Wire)

Size: 12 AWG / 10 AWG

Ampacity: 20–40A

12 AWG SIS electrical wire for electrical panel wiring was used extensively in control panels and PLC systems due to its high तापerature rating and compact structure, allowing dense wiring configurations while maintaining safety and performance, especially compared to standard THHN wires in high-temperature enclosures.

3. Cable Tray and Equipment Distribution System

Cable Type: TC-ER tray cable

Size: 4 AWG / 2 AWG

Ampacity: 85–130A

4 AWG TC-ER tray electrical cables were chosen for their ability to be installed directly in cable trays and partially exposed environments, with superior mechanical strength and flexibility, making them more suitable than rigid conduit wiring systems for long-distance industrial layouts and complex routing conditions.

Why These Cables Outperformed Alternatives

Compared to conventional cable options, the selected combination provided clear advantages:

XHHW-2: Better thermal stability and moisture resistance than standard building wire

SIS: Higher temperature tolerance and better space efficiency in control cabinets

TC-ER: Greater flexibility and mechanical durability for industrial installations

Additionally, the use of high-purity copper conductors and optimized insulation materials ensured improved conductivity, corrosion resistance, and extended service life.

Project Results and Client Feedback

With the implementation of this tailored cable solution, the project achieved:

• Stable high-load power transmission across all production units
• Reduced installation complexity and improved construction efficiency
• Enhanced system reliability under harsh environmental conditions
• Compliance with international electrical standards

The client reported that the cable system performed consistently under demanding operating conditions and has since initiated repeat procurement while recommending our solutions to other contractors involved in similar mining and industrial projects in the region.
