Description:

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tube are filled with a water-resistant filling compound. The tube is wrapped with a layer . The loose tube water-blocking material is applied to keep the cable compact and watertight. Multi steel wires are placed around of the central tube. The cable is completed with a polyethylene(PE) sheath.
