| ·产品描述 Description ADSS 光缆采用松套层绞式结构，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。松套管（和填充绳）围绕非金属中心加强芯（FRP）绞合成紧凑的缆芯，缆芯的缝隙充以阻水油膏。缆芯外挤制聚乙烯（PE）内护套，然后绞合起加强作用的芳纶，最后挤制聚乙烯（PE）外护套或耐电痕（AT）外护套。 ADSS cable is loose tube stranded. Fibers, 250μm , are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant filling compound. The tubes (and fillers) are stranded around a FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is filled with filling compound. it is covered with thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath. |
