gyfta53 光缆的结构是将 250μm 光纤套入高模量材料制成的松套管中,松套管内填充防水化合物。缆芯的中心是一根非金属加强芯(frp),对于某些芯数的光缆来说, 非金属加强芯外还需要挤上一层聚乙烯(pe)。松套管(和填充绳)围绕中心加强芯绞合成紧凑和圆形的缆芯,缆芯内的缝隙充以阻水填充物。涂塑铝带(apl)纵包后挤一层聚乙烯内护套,双面涂塑钢带(psp)纵包后挤制聚乙烯护套成缆。
the fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. the tubes are filled with a water-resistant filling compound. a fiber reinforced plastic (frp) 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. an aluminum polyethylene laminate (apl) is applied around the cable core. then the cable core is covered with a thin polyethylene (pe) inner sheath, which is filled with jelly to protect it from water ingress. after a corrugated steel tape armor is applied, the cable is completed with a pe outer sheath.
