South America – Medium Voltage XLPE Cable + Cold Shrink Terminations for Substation Expansion (Peru & Bolivia)

Project Background
Under national energy access expansion plans and substation modernization programs, Electroperu and ENDE Bolivia upgraded several 22 kV and 33 kV substations in 2023–2024. They required medium voltage XLPE cables and pre-tested cold shrink accessories suitable for mountainous environments, quick installation, and reliable long-term service.

Customer Challenges

• High-altitude terrain (3000+ meters above sea level)

• Require high-dielectric performance and reliable jointing

• Reduce installation time — prefer cold shrink over heat shrink

• Ensure system compatibility — cable + accessories from one supplier
