松套層絞式加強鎧裝光纜(GYTA53)

Stranded Loose Tube Armored Cable

產(chǎn)品描述 Description

GVTA53光纜的結(jié)構(gòu)是將250μm光纖套入高模量材料制成的松套管中，松套管內(nèi)填充防水化合物。纜芯的中心是一根金屬加強芯，對于某些芯數(shù)的光纜來說，金屬加強芯外還需擠上一層聚乙烯(PE)。松套管(和填充物)圍繞中心加強芯絞合成緊湊和圓形的纜芯，纜芯內(nèi)的縫隙充以阻水填充物。涂塑鋁帶(APL)縱包后擠制一層聚乙烯內(nèi)護套，雙面涂塑鋼帶(PSP)縱包后擠制聚乙烯護套成纜，適用：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.
