·產(chǎn)品描述 Description

GYHTY 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。纜芯的中心是一根玻璃纖維增強塑料（FRP），松套管（和填充繩）圍繞中心加強芯絞合成緊湊和圓形的纜芯 。纜芯內(nèi)的縫隙充以阻水油膏后擠制聚乙烯內(nèi)護(hù)套，再包上一層芳綸后擠制聚乙烯外護(hù)套成纜。

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. After the cable core is filled with filling compound, it is covered with thin PE (polyethylene) inner sheath. Then, a layer of aramid yarn is applied as additional strength member and the cable is completed with a polyethylene (PE) outer sheath.
