The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic.
The tubes are filled with a water-resistant filling compound.
The tube is wrapped with a layer of corrugated steel tape longitudinally. Between the corrugated
steel tape and the loose tube water-blocking material is applied to keep the cable compact
and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with PE sheath.
