產(chǎn)品描述：
GYXTW光纜結(jié)構(gòu)是：光纖位于帶纖膏的松套管中；松套管外縱包雙面涂塑鋼帶（PSP），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(cè)放置兩根平行鋼絲后擠制聚乙烯護套。
The fibers 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.
