| ·产品描述 Description GYFXY 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，两侧放置两根平行玻璃纤维增强塑料（FRP）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 Fiber Reinforced Plastics (FRP) are placed at the two side. The cable is completed with a polyethylene(PE) sheath. |
