8字形光纜
產(chǎn)品描述 Description
GYTC8A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(qiáng)芯,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。纜芯用一層涂塑鋁帶(APL)縱包后,和鋼絲絞線集成到一個(gè)8字型的聚乙烯護(hù)套內(nèi)。
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 locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.
