松套层绞式非金属加强芯普通铠装光缆(GYFTY53)

产品描述 Description

GYFTY53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。缆芯的中心是一根非金属加强芯(FRP),对于某些芯数的光缆来说,非金属加强芯外还需挤上一层聚乙烯(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 Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress. A layer of water-blocking material is applied around the cable core to prevent water ingress all the same. After a corrugated steel tape armor is applied, the cable is completed with a PE outer sheath.
