The fibres are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. A fibre reinforce plastic locates in the center of core as a non-metallic strength member. The tubes (and the fillers) are stranded around the strength member into a compact and circular core.And then the core wrapped with the swelling tape longitudinally. After part of cable accompanied with the stranded wires as the supporting part are completed with a PE sheath to be figure 8 structure.

Characteristics：

1.Excellent mechanical and temperature performance

2.Special tube filling compound ensure a critical protection of fibre and resist the water

3.Loose tube stranding cable core ensures the cable structure stable 

4.Loose tube completely filling compound to ensure the cable watertight 

5.High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation

6.Outer sheath protects cable from ultraviolet radiation

7.Optional  Aluminum or corrugated steel sheathing
