Stranded Loose Tube Non-metallic Strength Member Non-armored Cable　　 GYFTY 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。缆芯的中心是一根玻璃纤维增强塑料（FRP），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。 缆芯外挤上一层聚乙烯内护套成缆。 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. After the cable core is filled with the filling compound to protect it from water ingress, the cable is completed with a PE sheath. 产品特点 Characteristics ??????? · 具有很好的机械性能和温度特性??????? · Good mechanical and temperature performance ??????? · 松套管材料本身具有良好的耐水性能和较高的强度??????? · High strength looes tube that is hydrolysis resistant ??????? · 管内充以特种油膏，对光纤进行了关键性保护??????? · Special tube filling compound ensure a critical protection of fiber ??????? · 良好的抗压性和柔软性??????? · Crush resistance and flexibility ??????? · 采用下列措施来确保光缆的防水性能：??????? · The following measures are taken to ensure the cable watertight: ??????????????? - 单根非金属中心加强芯??????????????? - Single Fiber Reinforced Plastic as the central strength member ??????????????? - 松套管内填充特种防水化合物??????????????? - Loose tube filling compound ??????????????? - 完全缆芯填充??????????????? - 100% cable core filling ???????
