Central tube, Air-blown Micro-cable
1. The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic.
2. The tubes are filled with a water-resistant filling compound.
3. Aramid yarn located between central tube and outer sheath as a non-metallic strength member.
4. The cable is completed with a HDPE sheath.
