天津长飞鑫茂光缆有限公司

自承式架空光缆（GYTC8A）

    适用于：管道、架空、直埋。它的结构是:将250µm光纤套入高模材料制成的松套管中，松套管内填充防水化合物。缆芯的中心是一根金属加强芯，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。缆芯用一层涂塑铝带（APL）纵包后，和钢丝绞线集成到一个8字型的聚乙烯护套内。

The fibers, 250µm, are positioned in a loose tube made of a high modulus lastic. The tubes are filled with a water-resistant filling compound. A steel ire 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. YOFC（SH）figure 8 cable GYTC8Y, GYTC8S are also available on request. This type ofcable is specifically applied for self-supporting aerial installation.
