MGM 112 Type 331 Cable Application
MGM 112 Type 331 Cable is used to supply power to heavy mobile equipment such as excavators, crushers, and machinery. It is suitable for deep shaft mines (where explosive gases and dust may accumulate) and surface operation environments.
- Underground Mining (Longwall Cutters, Continuous Miners):
- Used to connect fixed power sources (power distribution centers) to longwall cutters or continuous miners.
- Open-Pit Mining (Grab Excavators, Scrapers, Large Mining Trucks):
- Supplies power to massive electric scrapers and grab excavators moving overburden and ore. On large dump trucks, the cable may be used for internal power distribution systems.
- Other Heavy Industrial Applications:
- Tunnel Boring Machines (TBMs): Operating in mining-like environments requiring continuous movement while enduring abrasion and moisture corrosion.
- Heavy quarrying equipment.
- Large industrial pumps in harsh environments.
MGM 112 Type 331 Cable Characteristics
Related standards | MGM 112/1984 |
Rated voltage | 1900/3300 V |
Test voltage | 7,5 kV |
MGM 112 Type 331 Cable Feature
- Excellent thermal stability: Withstands high-temperature operating environments (typical value 90°C) with robust overload and short-circuit performance.
- Flexibility: Maintains pliability in low-temperature conditions, critical for continuous movement and winding operations in mobile mining equipment.
- Moisture resistance: Offers outstanding waterproofing and moisture protection, effectively preventing electrical failures in humid mine environments.
- Abrasion and tear resistance: Withstands the harsh wear conditions of mining environments, serving as a key performance indicator.
