Comparison and references
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.

Quality Assurance
Testing at every stage in our own workshop and laboratory, from incoming copper to the packed drum.
Raw Material Inspection
Every batch of copper rod, rubber compound and reinforcing material is checked before it reaches the line.
- Copper: conductor resistance, elongation and surface condition on incoming rod and drawn wire
- EPR, CPE, PUR and silicone compounds: hardness, tensile strength, elongation and ageing samples from each mix
- Suppliers and batch numbers are recorded so every drum can be traced back to its materials
Manufacturing Process Control
Stranding, insulation extrusion, core assembly and sheathing run under recorded process parameters.
- Class 5/6 stranding with lay length and tension monitored for trailing and reeling flexibility
- Continuous-vulcanisation extrusion with wall thickness and spark tests logged on every length
- Operators sign off each stage before the cable moves to the next machine
Electrical Testing
Finished lengths go through the routine tests required by the referenced VDE, ICEA, IEC or NEK standard.
- Conductor resistance and insulation resistance on every length
- Voltage withstand (3.5 kV and higher) and partial-discharge measurement in the shielded HV laboratory
- Screen and pilot-core continuity checks for mining and reeling constructions
Mechanical and Ageing Tests
Samples from production are tested for the duty a mining, crane or submersible cable will actually see.
- Tensile strength and elongation of insulation and sheath before and after ageing
- Hot-set, ozone, oil-immersion and low-temperature bending tests
- Constant-temperature water bath for insulation resistance of submersible constructions
Flame Test and Final Inspection
Before packing, the cable is checked against the order and the flame-performance requirement of its standard.
- Single-cable vertical flame test to IEC 60332-1-2 where specified
- Metre marking, printing, drum length and appearance inspection
- Test report and packing list issued with every shipment
