(GYFTA) Stranded Loose Tube Non-metallic Strength Member Non-armored Cable


Stranded Loose Tube Non-metallic Strength Member Non-armored Cable(GYFTA)

More details


·产品描述 Description

GYFTA 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。缆芯的中心是一根非金属加强芯(FRP),对于某些芯数的光缆来说, 非金属加强芯外还需挤上一层聚乙烯(PE)。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,缆芯内的缝隙充以阻水填充物。涂塑铝带(APL)纵包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. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, the cable is completed with a PE sheath.

·产品特点 Characteristics

        · 具有很好的机械性能和温度特性
        · Good mechanical and temperature performance

        · 松套管材料本身具有良好的耐水性能和较高的强度
        · High strength loose tube that is hydrolysis resistant

        · 管内充以特种油膏,对光纤进行了关键性保护
        · Special tube filling compound ensure a critical protection of fiber

        · 特别设计的紧密的光缆结构,有效防止套管回缩
        · Specially designed compact structure is good at preventing loose tubes from shrinking

        · PE 护套具有很好的抗紫外辐射性能
        · PE sheath protects cable from ultraviolet radiation

        · 采用下列措施来确保光缆的防水性能:
        · The following measures are taken to ensure the cable watertight:

                - 单根非金属中心加强芯
                - Single Fiber Reinforced Plastic as the central strength member

                - 松套管内填充特种防水化合物
                - Loose tube filling compound

                - 完全缆芯填充
                - 100% cable core filling 

                - 涂塑铝带(APL)防潮层
                - APL moisture barrier
