MGM 111 Cable Application
MGM 111 Cable is used for feeding excavation and crushing machinery and equipment. It is also suitable for deep shaft mines (where explosive gases and dust may accumulate) and surface operations.
MGM 111 Cable Characteristics
| Related standards | MGM 111/1985 |
| Rated voltage | 1900/3300 V |
| Test voltage | 7,5 kV |
Why is the MGM 111 design critical for the mining industry?
- Safety: The grounding check conductor is an essential safety feature that prevents equipment from operating without proper grounding, significantly reducing the risk of electric shock.
- Durability: A robust outer jacket combined with a flexible stranded construction enables it to withstand crushing, dragging over sharp rocks, and exposure to chemicals.
- Flame Retardancy: The flame-retardant jacket, certified by the U.S. Mine Safety and Health Administration, prevents fire propagation—critical for underground mines.
- Flexibility: Meets the essential requirements for continuous operation of mobile mining equipment.
