电缆绳碳纤维，Carbon cable core.
碳纤维复合芯导线由碳纤维芯棒、铝线外层组成，外层与邻外层铝线股为梯形截面。使用SYT49碳纤维制造的复合芯导线浪拉强度可达到2400MP啊，是常规的刚新铝绞线抗拉强度的2倍，具有耐高温、载流量大、抗拉强度高、重量轻、弧垂小、节约杆塔费用及减少占地面积等一些列有点。
Carbon cable core made of carbon rod,aluminum rod outer layer.The outer layer and the adjacent outer wire strands of trapezoidal cross section.The use of SYT49 to produce composite core wire,tensile stenght can reach 2400MPa.It is 2 times of conventional steel cored aluminum strand tensile strength.It has a series of advantages,such sa good resistance to high temperature,large carrying capacity,high tensile strength,light weight,low cost save the towe sag and reduce the occupied area.
