·产品描述 description 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 ·产品标准 standards gyfty 光缆符合 yd/t 901-2001 和 iec 60794-1 标准 gyfty cable complies with standard yd/t 901-2001as well as iec 60794-1. ·光学特性 optical characteristics
