Fig 8 6 Core Fiber , GYTC8A, SM G652D,
Fig 8 6Core Fiber , GYTC8A, SM G652D Description:
The fibers 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 Aluminum Polyethylene Laminate (APL) 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.
