PE OUTER SHEATH Black PE sheath is extruded over the aluminum tape. Due to the process-heat,
CABLE MARKING both elements are perfectly bonded together providing a barrier against the penetration
of moisture. The thickness of the outer sheath is as shown in table (5)

Each length of cable has a longitudinal printing on the sheath surface indicating
the manufacturer, the month/year of manufacture, type of cables, number
of pair/conductor
• diameter and the running length.
• The color of marking will be white.
