GYXTC8S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，和钢丝绞线集成到一个8字型的聚乙烯护套内。

♦ 具有很好的机械性能和温度特性 Excellent 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 Special tube filling compound ensure a critical protection of fiber and resist the water.

♦ PE护套具有良好的抗紫外线功能 PE sheath protects cable from ultraviolet radiation.

♦ 完全缆芯填充  **** core filling water prevent cable jelly to ensure the cable watertight.

♦ 钢带纵向覆盖电缆芯作为防潮层  PSP longitudinal cover cable core as moisture barrier.

♦ 钢丝绞线具有极高的抗拉强度，便于自承式架空敷设，降低安装成本 High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation.
