Tension
The following values for tension should not exceeded for each conductor use.
Bending too close any internal and/or external anchorage shall avoided.
It recommended for those cases where the above values are exceeded, that separate strain-relieving element or
similar protection should used.
Torsional stress
In general, exible cables are not designed for torsional stress.

Attention shall given when stripping the insulation that the conductor not damaged this the bending

Bending stress
The internal bending radius cable should chosen such that the cable not damaged this.
If exible cables are subjected dynamic tensile stress (including those due the mass inertia, e.
