Uzbekistan is one of Central Asia’s largest producers of copper, gold, and uranium, with Navoi Mining & Metallurgy Combinat (NMMC) and Almalyk Mining-Metallurgical Complex (AMMC) leading underground and surface extraction. In 2023, as part of the country’s mining automation and electrification plan, NMMC expanded three major shafts and mobile mineral processing units across the Muruntau gold field — one of the largest open-pit mines in the world.
To support the high load mobility and safety of their mining systems, they required robust rubber-insulated mining cables, capable of enduring abrasion, mechanical dragging, and oil-water exposure, with long service life and zero safety compromise.
Uni-Cable, a global cable and accessories manufacturer, was chosen as the core supplier due to its:
Direct factory production (no middleman pricing)
Strict quality standards (ISO 9001, ISO 14001, ISO 45001 certified)
Rapid delivery capacity
Multilingual technical support in Russian/English/Chinese
| Model | Structure | Conductor | Voltage Rating | Application |
| (N)TSCGEWÖU 3x120+2x35+1x10 mm² | EPR insulated, textile-braided, PCP sheathed | Tinned copper Class 5 | 1.9/3.3 kV | Trailing cable for shuttle conveyor |
| NSSHöu 1x70 mm², 0.6/1kV | Flexible EPR, oil/flame resistant | Bare Cu | 0.6/1 kV | Pump power cable |
| NSSHöu 19x1.5 mm², 0.6/1kV | Multi-core control cable | Cu | 0.6/1 kV | Drill & lighting control |

The project team at NMMC praised Uni-Cable for its timely supply, system compatibility, and rugged performance. After 6 months of operation, the cables showed zero insulation faults or sheath damage, even in the high-vibration, mobile areas. The client has since placed new orders for shaft extension phases and recommended Uni-Cable to other state-owned mining groups.
