Low loss aluminium tube type OPGW power optical cable and manufacturing method thereof

The invention discloses a low loss aluminum tube type OPGW power cable and its manufacturing method, wherein, the cable from the inner core to the skin by the cable core wire, aluminum, composed of three parts, wherein the cable core is located in the center of the center of reinforcement and is around several stainless steel tube and twisted and, in the stainless steel tube is arranged in the fiber and fiber paste. In the invention, products using precision stainless steel tube instead of polybutylene terephthalate (PBT) process, the stranded structure of a plurality of the optical fiber cable and stainless steel pipe, seamless tube is covered with a layer of metal fiber as reinforced protection tube, the outer strands of one or more layers of aluminum clad steel wire or Aluminum Alloy. The present invention has excellent anti fatigue performance, electrochemical corrosion performance, better short-circuit current and lightning electrical characteristics, influence of short-circuit current on the transmission performance of the optical fiber, the optical fiber protection is perfect, no corrosion of worry, more suitable for the large short-circuit current of the line and extreme corrosion environment.

一种低损耗铝管式OPGW电力光缆及制造方法
本专利技术专利涉及一种光缆及其制造技术,主要用于电力领域,使用精密不锈钢管替代聚对苯二甲酸丁二醇酯(PBT)管工艺,而设计生产的一种新型低损耗铝管式OPGW电力光缆。
技术介绍
OPGW(OpticalFiberCompositeOverheadGroundWire)光缆是把光纤放置在架空高压输电线的地线中,用以构成输电线路上的光纤通信网,兼具地线与通信双重功能,目前采用普通聚甲基丙烯酸丁二醇脂(PBT)工艺保护光纤的方法,在恶劣环境强腐蚀条件下对光缆的使用寿命有较大影响。使用精密不锈钢管替代聚对苯二甲酸丁二醇酯(PBT)管工艺,而设计生产的一种新型低损耗铝管式OPGW电力光缆可以有效解决上述的问题。不锈钢管相对于PBT管具有不同的特性,传统的使用PBT管制作光缆的工艺并不适用,因此需要对该工艺进行重新设计。
技术实现思路
本专利技术要解决的技术问题是,提供一种高强度、耐腐蚀的光缆,并提供这种线缆的制作方法。
