| ·产品描述 Description GYXTW 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。松套管外用一层双面涂塑钢带（PSP）纵包，钢带和松套管之间加阻水材料以保证光缆的紧凑和纵向阻水，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. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath. |
