·產(chǎn)品描述 Description GYTA 光纜的結(jié)構(gòu)是將 250μm 光纖套入高模量材制成的松套管中，松套管內(nèi)填充防水化合物。纜芯的中心是一根金屬加強(qiáng)芯，對(duì)于某些芯數(shù)的光纜來(lái)說(shuō)，金屬加強(qiáng)芯外還需擠上一層聚乙烯（PE）。松套管（和填充繩）圍繞中心加強(qiáng)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（PL）縱包后擠制聚乙烯護(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 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. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath. ·產(chǎn)品特點(diǎn) Characteristics · 具有很好的機(jī)械性能和溫度特性 · Good mechanical and temperature performance · 松套管材料本身具有良好的耐水性能和較高的強(qiáng)度 · High strength looes tube that is hydrolysis resistant · 管內(nèi)充以特種油膏，對(duì)光纖進(jìn)行了關(guān)鍵性保護(hù) · Special tube filling compound ensure a critical protection of fiber · 特別設(shè)計(jì)的緊密的光纜結(jié)構(gòu)，有效防止套管回縮 · Specially designed compact structure is good at preventing loose tubes from shrinking · PE護(hù)套具有很好的抗紫外輻射性能 · PE sheath protects cable from ultraviolet radiation · 采用下列措施來(lái)確保光纜的防水性能： · The following measures are taken to ensure the cable watertight: - 單根鋼絲中心加強(qiáng)芯 - Steel wire used as the central strength member - 松套管內(nèi)填充特種防水化合物 - Loose tube filling compound - wq纜芯填充 - {bfb} cable core filling
