GDYTA33光電混合纜的結構是將單模或多模光纖套入由高模量的聚酯材料做成的松套管中，套管內填充防水化合物。 纜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的圓形纜芯，纜芯內的縫隙充以阻水填充物，內置電源線然后用雙面鍍鉻涂塑鋼帶（PSP）縱包后覆以聚乙烯內護套，內護套外一圈鋼絲鎧裝，最后用聚乙烯外護套成纜。

The structure of ELTFOC-GDYTA33 optical hybrid cable is that the single-mode or multi-mode optical fiber is sheathed in a loose tube made of high modulus polyester material, and the tube is filled with waterproof compound. The center of the cable is a metal reinforced core. The loose tube and the filling rope are twisted around the core to form a compact round core. The gap in the core is filled with water blocking filler. The power cord is built in, and then longitudinally wrapped with double-sided chrome coated plastic coated steel strip (PSP), and then covered with polyethylene inner sheath. The outer ring of the inner sheath is steel wire armored. Finally, the cable is formed with polyethylene outer sheath.

產品特性：

1.精確控制光纖的余長保證了光纜具有很好的抗拉性能和溫度特性。
2.PBT松套管材料具有良好的耐水解性能，管內充以特種油膏，對光纖進行保護
3.采用采用涂塑鋼帶防潮層。

Feature：?

1. The precise control of the surplus length of the optical fiber ensures that the optical fiber has good tensile properties and temperature characteristics.
2. The PBT loose tube material has good hydrolysis resistance, and the tube is filled with special grease to protect the optical fiber
3. Apply plastic coated steel strip damp proof layer.
