What’s NSSHCGEÖU(V) vs NSSHCGEÖU(Z) Reinforced Version Cable
1. Construction Differences (Key Points)
Conductor & Stranding
- (V): Class 5 tinned copper, standard stranding
- (Z) Reinforced: Class 5 FS (extra-fine stranded): higher flexibility, better torsion resistance
Pilot / Monitoring Cores
- (V): Standard copper–steel composite pilot cores
- (Z) Reinforced: Reinforced steel braid + thicker semiconductive layer → better crush/impact resistance
Armour / Concentric Earth (Critical Difference)
- (V): Copper–steel wire braid, standard density
- Tensile strength: ~15 N/mm²
- (Z) Reinforced: High-density double-layer copper–steel braid + optional aramid reinforcement
- Tensile strength: ~30 N/mm² (double)
- Higher torsion resistance: ±50°/m vs standard ±25°/m
| Parameter | NSSHCGEÖU(V) Standard | NSSHCGEÖU(Z) Reinforced |
|---|---|---|
| Rated voltage | 0.6/1kV | 0.6/1kV |
| Tensile strength | ~15 N/mm² | ~30 N/mm² (double) |
| Torsion capability | ±25°/m | ±50°/m (double) |
| Min. bending radius | 10×OD | 8×OD (tighter bend) |
| Reeling speed | Standard | Up to 160 m/min (high speed) |
| Impact/crush resistance | High | Extreme |
2. Applications
NSSHCGEÖU(V) – Standard Use
- Coal cutters, shearers, light–medium LHDs
- Normal trailing, frequent bending, moderate tension
- Underground mines, wet/oily/dusty areas, occasional shallow water
NSSHCGEÖU(Z) Reinforced – Heavy-Duty Use
- Heavy LHDs, TBMs, long-wall equipment
- High-speed drum reeling, tight sheaves, vertical shafts
- Extreme tension, torsion, crush/impact loads
- Long service life required; less downtime for replacement
3. Short Summary
- (V) = Standard tensile & torsion, general mining mobile equipment.
- (Z) Reinforced = Double tensile + double torsion + tighter bending, for heavy/high-speed mining machinery.
