·产品描述 Description 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**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. ·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**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**化合物 - Loose tube filling compound - *缆芯填充 - ** cable core filling - 涂塑铝带(APL)防潮层 - APL moisture barrier - 双面涂塑钢带(PSP)提高光缆的抗透潮能力 - PSP enhancing moisture-proof - 良好的阻水材料防止光缆纵向渗水 - Water-blocking material ·产品标准 Standards GYFTY53 光缆符合 YD/T 901-2001 和 IEC 60794-1 标准 GYFTY53 cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
