·产品描述 Description 室外光缆GYFXTY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。松套管外加阻水材料以保证光缆纵向阻水，两侧放置两根平行钢丝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. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. The cable is completed with a polyethylene (PE) sheath. · 具有良好的机械性能和温度性能 · 松套管材料本身具有良好的耐水解性能和较高的强度 · 管内充以特种油膏，对光纤进行了关键性保护 · 两根平行钢丝保证光缆的抗拉强度 · PE 护套具有很好的抗紫外辐射性能 · 直径小、重量轻、容易敷设 · 较长的交货长度 ·产品标准 Standards GYXY 光缆符合 YD/T 769-2003 标准
