供应松套中心束管式光缆

松套管中心束管式铠装光缆 Stranded Loose Unitube light armored cable 产品描述 Description 光缆的结构是将250光纤套入高模量材料制成的松套管中，松套管内填充防水材料。松套管外用一层双面涂塑钢带（PSP）纵包，钢带和松套之间加阻水材料以保证光缆的紧凑和综向阻水，两侧放置两根平行钢丝后挤制聚乙烯护套成缆。 The fibers, 250m, 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. 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解性能和较高的强度 High strength loose 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 双面涂塑钢带（PSP）提高光缆的抗透潮能力 PSP enhancing moisture-proof 两根平行钢丝保证是的抗拉强度 Two parallel steel wires ensure tensile strength 直径小、重量轻、容易敷设 Small diameter, light weight and friendly installation 较长的交货长度 Long delivery length
