PRODUCT DETAILS

Figure 8 self-supporting aerial cable GYTC8S

The fibers, either 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 steel wire locates in the center of core as a 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.

INQUIRY
This specification covers the general requirements of Figure 8 self-supporting cable for aerial , duct and direct buried.
· Accurate fiber excess length ensure a good performance of tensile strength and temperature.
· High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber.
· The following measures are taken to ensure the cable watertight:
Steel wire as the central strength member
Loose tube filling compound
100% cable core filling
PSP enhancing moisture-proof
