·產品描述 Description GYXTW 光纜的結構是將 250μm 光纖套入高模量材料制成的松套管中，松套管內填充防水化合物。松套管外用一層雙面涂塑鋼帶（PSP）縱包，鋼帶和松套管之間加阻水材料以保證光纜的緊湊和縱向阻水，兩側放置兩根平行鋼絲后擠制聚乙烯護套成纜。 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. ·產品特點 Characteristics · 具有良好的機械性能和溫度性能 · Good mechanical and temperature performance · 松套管材料本身具有良好的耐水解性能和較高的強度 · High strength loose tube that is hydrolysis resistant · 管內充以特種油膏，對光纖進行了關鍵性保護 · Special tube filling compound ensure a critical protection of fiber · 良好的抗壓性和柔軟性 · Crush resistance and flexibility · 雙面涂塑鋼帶（PSP）提高光纜的抗透潮能力 · PSP enhancing moisture-proof · 兩根平行鋼絲保證光纜的抗拉強度 · Two parallel steel wires ensure tensile strength · 直徑小、重量輕、容易敷設 · Small diameter, light weight and friendly installation · 較長的交貨長度 · Long delivery length
