供应耐斯龙中心管式非??光?（GYXY）

·产品描述 Description

GYXY 光缆的结构是将 250μm 光纤套入高模量材料制成的松套管中，松套管内填充防水化合物。松套管外加阻水材料以保证光缆纵向阻水，两侧放置两根平行钢丝后挤制聚乙烯护套成缆。

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. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. The cable is completed with a polyethylene (PE) sheath.
