Cable stiffness

Illustrated explanation

Keep the bend away from the termination

5Cable stiffness
Keep the bend away from the terminationCallout 1: Bend protection. Callout 2: Spiral support. Callout 3: Tapered boot. Callout 4: Bend radius. Callout 5: Cable stiffness. Curvature, stiffness and a supporting boot influence the load reaching a cable entry. A spiral support is different from the cable’s permitted minimum bend radius.

  1. Bend protection

    A support limits abrupt curvature near the entry. Its stiffness and length must suit the cable and movement.

  2. Spiral cable gland

    The spiral guides the cable through a gradual bend. It does not establish a universal flex life or bend limit.

  3. Strain-relief boot

    A tapered boot spreads bending near a termination. It can complement axial grip, but its presence does not prove retention duty.

  4. Bend radius

    The radius measures cable curvature at the stated reference. Verify which surface or centreline the cable specification uses.

  5. Cable stiffnessThis term

    Different cables resist bending differently. Route and support them so the entry is not used as a lever or structural anchor.

Curvature, stiffness and a supporting boot influence the load reaching a cable entry. A spiral support is different from the cable’s permitted minimum bend radius.

Conceptual cable routes without numerical radii. Follow the actual cable and entry instructions for static or repeated movement.
