Overview of the OT Mining Project
The Oyu Tolgoi mining project is located in the South Gobi Desert of Mongolia. The project is recognized as one of the largest copper and gold mines in the world. Because the deposit contains enormous mineral reserves, the mine includes both open-pit and underground operations.
তাছাড়া, the mining complex requires a highly reliable electrical power system. Large crushers, conveyor systems, পাম্প, and ventilation equipment consume enormous amounts of electricity. ফলে, the mining infrastructure depends on a strong and stable power distribution network.
উপরন্তু, mining facilities operate continuously. Equipment often runs 24 hours per day. এই কারণে, electrical systems must deliver stable performance without interruptions. Reliable cables help prevent downtime and reduce maintenance costs.
Electrical Infrastructure Requirements in Mining
Mining projects require complex electrical networks. প্রথম, power must travel from transmission lines to substations. পরবর্তী, medium-voltage cables distribute electricity across the mining site. অবশেষে, low-voltage cables supply power to equipment and facilities.
Because of these requirements, several cable types are typically used in mining projects.

High-Voltage Transmission Systems
High-voltage lines deliver electricity from the national power grid to mining substations. These systems usually operate at voltages such as 110 কেভি, 220 কেভি, or even higher. ফলে, mining facilities receive sufficient power for heavy industrial equipment.
Medium-Voltage Distribution
After electricity reaches the mining substation, engineers distribute power through medium-voltage cables. These cables commonly operate at 6 কেভি, 10 কেভি, বা 35 কেভি. They supply energy to crushers, grinding mills, and processing equipment.
Low-Voltage Power Systems
Low-voltage cables supply power to lighting systems, পাম্প, conveyor belts, and maintenance facilities. Although these systems operate at lower voltages, they remain essential for daily mining operations.
অতএব, mining projects require a wide range of cable products with different voltage ratings and structural designs.

Power Cable Types Supplied to Mining Projects
Mining operations require several specialized cable types. Each cable type performs a different function within the electrical network.
XLPE Insulated Power Cable
Cross-linked polyethylene insulation provides excellent electrical performance and thermal stability. Because XLPE insulation allows higher operating temperatures, cables can carry larger electrical loads.
ফলে, XLPE power cables are widely used in both low-voltage and medium-voltage mining systems.
Typical advantages include:
- High temperature resistance
- Excellent insulation performance
- দীর্ঘ সেবা জীবন
- Strong resistance to electrical aging
Armored Power Cable
Mining environments often expose cables to mechanical stress. Heavy equipment, vibrations, and rock movement can damage ordinary cables. অতএব, armored cables provide additional mechanical protection.
Steel tape armor or steel wire armor protects the cable core from crushing forces. ফলে, armored cables are ideal for underground installation and harsh industrial environments.
Flexible Mining Cable
Certain mining equipment requires cables that can move with machinery. Flexible cables support mobile equipment such as drilling machines and transport systems.
Because these cables bend repeatedly during operation, they require special insulation materials and flexible conductor designs.

Typical Power Cable Structure
Although cable designs vary depending on application, most mining power cables follow a similar structural design.
| Layer | উপাদান | Function |
|---|---|---|
| কন্ডাক্টর | তামা | Conducts electrical current |
| অন্তরণ | এক্সএলপিই | Provides electrical insulation |
| Inner sheath | পিভিসি | Protects insulation layer |
| Armor layer | Steel tape or wire | Provides mechanical protection |
| Outer sheath | PVC or PE | Protects against environment |
Each layer performs a specific function. একসাথে, they ensure reliable power transmission in demanding mining environments.
Conductor Size Range
Mining operations require cables with different conductor sizes to support various power loads. DOS Cable provides a wide range of conductor sizes suitable for industrial applications.
| Cable Type | Conductor Size Range |
|---|---|
| Low-voltage cable | 1.5 mm² – 800 মিমি² |
| Medium-voltage cable | 25 mm² – 630 মিমি² |
| Armored cable | 4 mm² – 400 মিমি² |
Because mining equipment requires large electrical currents, larger conductor sizes often appear in processing plants and main power distribution systems.
