DCFA 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)放入特種阻水紗對(duì)光纖進(jìn)行關(guān)鍵性保護(hù)。纜芯的中心是一根非金屬加強(qiáng)芯(FRP),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。松套管及加強(qiáng)芯外均設(shè)有阻水紗,纜芯上縱包阻水帶,進(jìn)行涂塑鋁帶(APL)縱包后,擠制聚乙烯護(hù)套成纜。
產(chǎn)品特點(diǎn)
● 具有很好的機(jī)械性能和溫度特性
● 松套管材料本身具有良好的耐水解性能和較高的強(qiáng)度
● 松套管內(nèi)放入特種阻水紗,對(duì)光纖進(jìn)行了關(guān)鍵性保護(hù)
● 特別設(shè)計(jì)的緊密的光纜結(jié)構(gòu),有效防止套管回縮
● PE 護(hù)套具有很好的抗紫外輻射性能
● 采用下列措施來(lái)確保光纜的防水性能:
- 單根非金屬中心加強(qiáng)芯
- 松套管內(nèi)特種阻水紗
- 松套管和加強(qiáng)芯外阻水紗
- 纜芯外阻水帶
- 涂塑鋁帶(APL)防潮
