Thickness conductor tape

This is an optional tape wrapped around the conductor.

In case of paper-insulated cables, this is considered a metallic tape, and electrically and thermally negligible.
In case of all other cables, this is considered to be semi-conducting insulating tapes forming an unity with the conductor shield.
