松套层绞式加强铠装光缆(GYTA53)

Stranded Loose Tube Armored Cable

产品描述 Description

GVTA53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，金属加强芯外还需挤上一层聚乙烯(PE)。松套管(和填充物)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。涂塑铝带(APL)纵包后挤制一层聚乙烯内护套，双面涂塑钢带(PSP)纵包后挤制聚乙烯护套成缆，适用：管道、架空、直埋。

The fibers,250μ m,are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistantfiling compound.A steel wire,sometimes sheathed with polyethyene(PE)for cable with high fiber count,locates in the centerof core as a metallic strength member.Tubes(and fillers)are stranded around the strength member into a compact and circularcable core.An Aluminum Polyethylene Laminate(APL)is applied around the cable core,which is filed with the filing compoundto protect it from water ingress.then the cable core is covered with a thin PE inner sheath .After the PSP is longitudinallyapplied over the inner sheath,the cable is completed with a PE outer sheath Application:Ducr/aerial/Direct buried.
