·產品描述 Description
GYTC8A 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。纜芯的中心是一根金屬加強芯，松套管（和填充繩）圍繞中心加強芯絞合成緊湊和圓形的纜芯，纜芯用一層涂塑鋁帶（APL）縱包后，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. A steel wire locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, 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.
·產品特點 Characteristics
· 鋼絲絞線具有極高的抗拉度，便于自承式架空敷設，降低安裝成本
· High tensile strength of stranded wires meet the requirement of self-supporting and reduce the
installation cost.
· 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
· 采用下列措施來確保光纜的防水性能：
· The following measures are taken to ensure the cable watertight:
- 單根鋼絲中心加強芯
- Steel wire used as the central strength member
- 松套管內填充特種防水化合物
- Loose tube filling compound
- 完全纜芯填充
- 100% cable core filling
- 涂塑鋁帶（APL）防潮層
- APL moisture barrier
