Summary of Use Cases
| Use Case | Best Option |
|---|---|
| Halogen-free & low smoke areas (e.g., indoors, tunnels) | Trommelflex PUR-HF |
| Heavy-duty, high core-count systems (e.g., cranes, mining reels) | Cordaflex 46×1 |
| Water-resistant & outdoor rated applications | Trommelflex PUR-HF |
| Festoon or rapid reel operations with high mechanical stress | Cordaflex 46×1 |
Verdict
- Choose Trommelflex PUR-HF if you need a halogen-free, environmentally safer, medium-duty reeling cable.
- Choose Cordaflex 46×1 if your system requires large multi-core construction, mining or high-load environments, and can tolerate non-halogen-free PCP materials.
