GYFS全干式光缆 光纤电缆

全干式光缆totally dry cable：GYFS

产品描述：
    GYFS光缆结构是：光纤位于带阻水纱的松套管中；缆芯中心是非金属加强芯FRP（可能会加PE垫层），FRP周围由松套管、填充绳绞合而成，缆芯内的间隙填充阻水纱，缆芯外包阻水带；最后光缆挤塑钢聚乙烯护套。
The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with water blocking yarns. A Fiber Reinforced Plastic (FRP) (may PE blanket) 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 core. The cable core is filled with the water blocking yarns .Then ,A water blocking tape  is applied around the cable core. After An steel Polyethylene Laminate（PSP） moisture barrier is applied around the cable core, the cable is completed with a PE sheath.

光缆芯数范围：2～288芯            

Optical cable core number: 2 ~ 288 core
