Direct answer
What this result means
Calculate cable centreline arc length and chord length from a stated bend radius and bend angle. The relationship s = Rθ ties bend centreline radius and bend angle directly to the reported result. The bend follows one constant-radius circular arc. 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.
s = Rθ defines the calculation shown here. The bend follows one constant-radius circular arc. Keep the entered units with the result so another reviewer can reproduce the method.

Variables
Use sequence
From measurement to review
- Confirm bend centreline radius and bend angle from a controlled drawing, measurement or project document.
- Apply s = Rθ with consistent units and keep the entered values beside the result.
- Use centreline arc length only after checking the required cable bend radius, centreline definition and straight allowances at each end.
Limits
What this calculation does not confirm
- The bend follows one constant-radius circular arc.
- 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.
