The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member to form the cable core.The cable core is filled with water blocking compound and PE inner jacket is extruded. Then the aramid yarn twist around the inner jacket to reinforce . Finally, PE outer jacket or AT outer jacket is completed.
