Recommendations
Minimum cable bending radius
The internal radius of cable bends which are not subjected to movements by expansion, is not to be less than :
6 times the external diameter of cable
Cable which are subjected to movements by expansion and the high voltage cable are to be bent to a form of at least 12 times cable diameter.
Installations temperature
Minimum recommended temperature of installations :
-10°C Ship wiring cable with PVC sheath
-20°C Elastomeric on/off shore cables
Installations pulling force
The cable pulling force can be estimated, as a maximum limit :5Kp per mm2 conductor area in the cable.Additional tension will be supplied from the braid and the insulation
and sheathing compound.
