Peru is one of the world’s largest copper producers, with extensive mining operations in the Andes Mountains. The harsh operating conditions in underground and open-pit mines — including extreme mechanical stress, moisture, abrasive soil, and high electrical loads — demand highly durable and flexible mining cables. For this project, Uni-Cable supplied mining-grade rubber cables and compatible couplers to support heavy-duty drilling machines, conveyors, and electrical submersible pumps (ESPs) in a major copper mining complex.
Uni-Cable provided a comprehensive portfolio of rubber-sheathed mining cables, specifically engineered to meet VDE 0250, DIN EN 50525, and IEC 60245 standards. The supplied models included:
(N)TSCGEWÖU 3x120 + 2x35 + 1x10 mm², Cu
Application: Flexible trailing cable for heavy mining equipment and mobile machinery
Features: Excellent tensile strength, resistant to oil, moisture, and mechanical wear
(N)TSCGEWÖU 3x70 + 2x35 + 1x16 mm², Cu
Application: Power supply to medium-sized mining shovels and drilling rigs
Features: UV and ozone resistance for surface mining operations
NSSHöu 1x70 mm², Cu
Application: Suitable for extreme mechanical stress, typically for pumps and cutting machines
Features: Extra-heavy duty rubber sheath, flame retardant
NSSHöu 19x1.5 mm², Cu
Application: Control and signal cable for mining machinery automation
Features: High flexibility, resistant to repeated bending cycles
Couplers and Connectors (custom-matched to above cables)
Application: Quick and safe connection/disconnection in harsh environments
Features: IP68 waterproofing, corrosion-resistant alloys, and heat-treated contacts
The copper mining project required a safe, reliable, and long-lasting power distribution solution for both fixed and mobile applications. Uni-Cable’s mining cables solved several challenges:
Durability: Resistant to abrasion from rocks and soil in open-pit environments.
Flexibility: Maintained performance even with constant reeling/unreeling in underground tunnels.
Safety: Flame-retardant and low-smoke properties reduced fire hazards in confined mining shafts.
Efficiency: Pre-fitted couplers simplified field installation, reducing downtime during equipment relocation.
All cables underwent strict quality control:
Electrical Tests: Dielectric strength, insulation resistance, partial discharge tests
Mechanical Tests: Tensile load, bending cycles, and abrasion resistance
Environmental Tests: Oil resistance, water immersion, UV and ozone stability
Certifications: IEC, VDE, ISO 9001, ISO 14001, and OHSAS 18001
Shipping: Delivered through Callao Port, Peru, with on-time logistics ensuring installation aligned with mining project schedules.
The mining operator reported significant improvements in cable reliability and reduced downtime due to cable damage. Uni-Cable’s factory-direct sales model provided competitive pricing, and fast delivery schedules ensured critical project milestones were met. The customer recognized Uni-Cable as a long-term cable partner for future mining expansions in Peru and other Latin American markets.
