NSSHCGEOEU — TEBAOFLEX MV Reeling Cable with Twin Control + Monitoring
What Makes NSSHCGEOEU Different
The NSSHCGEOEU is the most conductor-dense variant in the TEBAOFLEX MV reeling family. While the base (N)TSCGEWÖU MT carries 3 power + 3 earth cores, NSSHCGEOEU adds two twisted control pairs (2ST) and one or more monitoring conductors (ÜL) inside the same outer diameter. This design serves two purposes simultaneously: delivering MV power to the machine and providing a dedicated channel for condition monitoring signals (temperature, vibration, oil analysis) without an extra cable.
| Variant | Power | Earth | Control | Monitoring |
|---|---|---|---|---|
| (N)TSCGEWÖU MT (base) | 3 | 3 | — | — |
| NSSHCGEOEU | 3 | 3 | 2×ST (twisted pair) | ÜL conductor(s) |
| (N)TSCGEWOEU-TR | 3 | 3 | — | — (torsion rated) |

When to Specify NSSHCGEOEU
| Scenario | Why NSSHCGEOEU |
|---|---|
| Large excavator with condition monitoring | ÜL conductors carry sensor data; no second cable needed |
| Shovel with onboard auxiliary controls | 2ST control pairs handle start/stop and interlocks |
| Dragline with health monitoring system | Real-time vibration and temperature over ÜL loop |
| Project reducing cable clutter on boom | One cable replaces three (power + control + monitoring) |
| Existing (N)TSCGEWÖU MT insufficient | Add control and monitoring without increasing cable count |
Key Advantages
- Eliminates the cost and weight of a separate control + monitoring cable
- ÜL conductors compatible with PT100, accelerometer, and current loop sensors
- ST pairs individually screened for EMC in VFD environments
- Same 5GM5 red sheath, same tensile and torsion rating as the base MV range
- Full VDE 0250-813 type approval
