Steel wires in the cable for communication
The fibers,either of single-mode ormultimode type , are placed in a loose tube made of high modulus plastic. The tubes are filledwith a water resistant filling compound. A FRP 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 water blocking tape 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.
Very strict material and manufacturing control guarantees the cable can work stably for more than 30 years.
Total cross-section water-resistant structure makes cable have excellent properties of moisture resistance Special jelly filled in the loose tube provides the fibers with critical protection Figure-8 self-supporting structure, high tension strength, facilitate in aerial, low installation costs Steel wires in the cable for electric communication.
