标题: 供应耐斯龙层绞式普通铠装光缆（GYTY53）

·产品描述 Description

GYTY53 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。缆芯的中心是一根金属加强芯，对于某些芯数的光缆来说，金属加强芯外还需要挤上一层聚乙烯（PE）。松套管（和填充绳）围绕中心加强芯绞合成紧凑和圆形的缆芯，缆芯内的缝隙充以阻水填充物。缆芯外挤上一层聚乙烯内护套，双面涂塑钢带（PSP）纵包后挤制聚乙烯护套成缆。

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, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
