Difference between NTMCGCWOEU and NTMTWOEU
1. NTMCGCWOEU
- Full name: Multi-core cable with concentric earth conductor + control cores
- Structure: Power cores + central concentric earth wire + auxiliary/control cores, overall screened
- Features: Built-in dedicated earth & control lines; enhanced grounding & signal transmission
- Use case: Mining machinery, draglines, LHDs, equipment needing power + control + reliable earthing in harsh sites
2. NTMTWOEU
- Full name: Multi-core cable with only power cores (no integrated control/central earth)
- Structure: Pure power conductor cores, basic rubber insulated, overall reinforced sheath
- Features: Simplified structure, higher flexibility, lighter, for pure power supply
- Use case: General mobile mining equipment, hoists, conveyors, only power transmission (no control signal)
