You may want to follow the below steps in breaking down the sheathing process as any raised wire can be detected through a double sheathing process.

  • The inner sheathing layer should be extruded.
  • An inspection of the full wire rope length should be carried out in order to detect any raised wire through the first layer. To facilitate this inspection, the inner layer should have a color contrasting that of the galvanized wires.
  • Then only after the validation of this inspection, the outer sheathing layer should be extruded.

You should also pay attention on closing the cross-section and keeping the wire assembly as compact as possible as shown in the picture below.

Prior to the sheathing process, the entire wire length should be checked by visual inspection to detect any raised wire and defects in the outer layer.
