Direct answer
What this result means
Calculate a preliminary tension-to-radius sidewall pressure index for cable routed around a bend. The relationship Psw = T / R ties cable pulling tension and bend radius directly to the reported result. Tension and bend radius describe one controlled bend condition. Treat the value as a transparent preliminary calculation, then compare it with the actual cable-entry assembly and current product documentation.
Formula & theory
Make the assumptions visible.
Psw = T / R defines the calculation shown here. Tension and bend radius describe one controlled bend condition. Keep the entered units with the result so another reviewer can reproduce the method.

Variables
Use sequence
From measurement to review
- Confirm cable pulling tension and bend radius from a controlled drawing, measurement or project document.
- Apply Psw = T / R with consistent units and keep the entered values beside the result.
- Use sidewall pressure index only after checking the cable manufacturer’s sidewall-pressure definition, bend geometry, pulling direction and allowable limit.
Limits
What this calculation does not confirm
- Tension and bend radius describe one controlled bend condition.
- Inputs describe one defined operating or measurement condition and use mutually consistent units.
- The result does not by itself confirm product suitability, standards compliance, ingress performance or installation approval.
