·產品描述 Description
GYXTC8S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，和鋼絲絞線集成到一個8字型的聚乙烯護套內。 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 two sides PSP are longitudinally applied over the outer loose tube. Steel wires and loose tubes filled with water proof compound to ensure compact and longitudinally water blocking ,this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure.
