The Sheath marking

The color of marking is white, but if the remarking is necessary, the white color marking shall be printed newly on a different position.
An occasional unclear of length marking is permitted if both of the neighboring markings are clear.
Both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
