Figure 8 Self-supporting Aerial (overhead) Cable
The fibers,either of single-mode or multimode type, are placed in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A FRP locates in the center of core as a non- metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After PSP is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation.
This specification covers the general requirements of Figure 8 self-supporting cable for aerial
1. Accurate fiber excess length ensure a good performance of tensile strength and temperature.
2. High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber.
3. The following measures are taken to ensure the cable watertight:
FRP as the central strength member
Loose tube filling compound
100% cable core filling
PSP enhancing moisture-proof
