Cable Pulling Tension and Sidewall Pressure Limits
Cable Pulling Tension and Sidewall Pressure Limits reference with assumptions and boundary notes.
Reference boundary
Formula example only. Cable manufacturer limits, raceway condition, lubricant, bend sequence, pulling setup, and qualified review govern pull acceptance.
Reference table
Show basic pulling-tension and sidewall-pressure arithmetic relationships for preliminary pull planning.
| Scenario | Cable weight (kg/m) | Straight length (m) | Friction coefficient | Estimated tension (N) | Bend radius (m) | Sidewall pressure (N/m) |
|---|---|---|---|---|---|---|
| Straight pull example | 2 | 100 | 0.5 | 981 | 0.6 | 1634 |
| Longer pull example | 2 | 150 | 0.5 | 1471 | 0.6 | 2452 |
| Lower friction example | 2 | 100 | 0.35 | 686 | 0.6 | 1144 |
| Larger bend radius example | 2 | 100 | 0.5 | 981 | 0.9 | 1090 |
Use notes
- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
