The aerial fiber cable structure of GYTC8S is to put the fibers 250μm into PBT loose tube, which is filled with water-resistant filling compound. The cable center has a strength member, which can be metallic or non-metallic. The tubes or fillers are stranded around the central strength member into a compact and circle cable core. An Aluminum Polyethylene Laminate(APL) is applied around the core cable. This part of cable accompanied with the stranded wires as supporting part is completed with a polyethylene(PE) sheath to be figure 8 structure.
1, Stranded wires has very good tensile strength, which is good for self-supporting aerial installation and cost saving.
2, Good mechanical and temperature performance.
3, Loose tube material itself has good water resistance and high strength.
4, Special tube filling compound protect the core fibers critically.
5, The following measures are taken to ensure the cable watertight
Loose tube is filled with special water proof materials.
100% cable core filling
