OPGW光缆不同结构特点解析

单层中心不锈钢管OPGW光缆

结构特点及应用
·缆径小，重量轻，短路电流容量小
·光单元形成适宜的一次光纤余长
·抗拉伸、抗扭力、 抗侧压性能较差
·适合与GJ-35、GJ-50、GJ-70匹配
Structure Characteristic and Application
·Small cable diameter and short-circuit current capacity,light weight
·Obtaining appropriate primary fiber excess length within SUS tube
·The OPGW has a bit poor tensile,torsion and crush resistance performance
·Matching with GJ-35,GJ-50 and GJ-70 diffluent ground wirc

两层层绞不锈钢管OPGW光缆

结构特点及应用
·缆径较大，光纤较多
·抗拉强度和短路电流容量较大，达到机械和电气性能最佳平衡
·光单元数量可以是1个，目前最多3个
·最佳的绞合技术，获取二次光纤余长
·绞线层数可设计两层或三层，单丝可为铝包钢线和/或铝合金线、铝线的组合
Structure Characteristic and Application
·Bigger cable diameter and higher fiber count
·The best balance of mechank performance for the bigger RTS and fault current capacity
·Quantity of SUS OP-Unit could be 1.2 or 3(max at present)
·Optimum stranding design,making primary and secondary fiber excess length
·The stranded layer could be single,double layers or three layers,the stranded wire could be AS wires with/or AA and AL wires

中心铝包不锈钢管OPGW光缆

结构特点及应用
·铝包钢管光单元增大了铝界面，更优的短路电流和雷击电气特性
·极佳的耐电化学腐蚀性能
·填补缆径为11.4-13.5mm空白结构设计
·适用于要求小直径、较大短路电流的线路
·极端腐蚀环境，加沿海、化工区域
Structure Characteristic and Application
·AL-covered SUS tube design increasing AL sectional area, the better fault current and lightning  resistance performance
·Extremely good corrosion resistance
·Filling up the vacant cable diameter design of 11.4-13.5mm
·Used in the transmission line which specifires the small cable diameter and bigger fault current
·Extremely corrosion condition,such as littoral,chemical areas
