Description

一种绳索式复合芯
技术领域
 本实用新型涉及电线电缆领域，尤其涉及一种绳索式复合芯。
背景技术
随着我国经济建设的不断发展，电力需求的不断增长，电缆作为电能传输的载体的需求量也越来越大，而目前国内用的电缆导线多是钢芯铝绞线和钢芯铝合金导线，这些导线的重量较大，电阻较大，从而导致输电费用高，且运行温度较低，不能适应在高温条件下的运行，因此电力传输成为电力工业发展的“瓶颈”，各国均在研究新型架空输电路用导线，以取代传统的钢芯铝绞线。
碳纤维复合芯电缆与传统的钢芯铝绞电缆相比较具有以下优点：
(1)重量轻：碳纤维复合芯的密度是钢的密度为的1/4。因此,架空电缆的杆塔跨距可增长,减少塔杆数约为16%左右,同时减少占地面积。
(2)强度高，破断力大。碳纤维复合芯电缆的拉伸强度约为2399MPa ,是普通钢丝的1.97倍,是高强度钢的1.17倍。
(3)导电率高,载流量大。相同直径碳纤维复合芯电缆中的铝线截面积是常规钢芯铝绞电缆的1.29倍,载流量提高29%左右。
(4)线路损耗小。碳纤维复合材料是一种非磁性材料,当导线通过交流电时不会产生磁滞损耗和涡流损耗,呈现出更小的交流电阻。
(5)耐腐蚀,使用寿命长。碳纤维复合芯棒避免了钢芯在通电时铝线与镀锌钢丝之间的电化学腐蚀,使铝导线长期使用而耐老化。
(6)线膨胀系数小,弛度小。
但是，现有技术中的碳纤维电缆芯柔软性不好，弯曲半径大，做成的导线弯曲性能不好。
发明内容
本实用新型所要解决的技术问题是克服现有技术中碳纤维电缆芯柔软性不好、弯曲半径大的缺陷，提供一种绳索式复合芯。
本实用新型解决其技术问题所采用的技术方案是：
一种绳索式复合芯，其特征在于，采用碳纤维丝为主要材料，通过将成股的碳纤维丝绞合后，采用树脂浸渍，而后采用烘箱固化而成。
本实用新型的有益效果是：经过树脂浸渍并采用烘箱固化后的碳纤维丝，质地柔软，制成的电缆比传统碳纤维电缆芯柔软性好，做成导线后具有更小的弯曲半径，能更好的服务于输电线路。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示，一种绳索式复合芯，采用碳纤维丝1为主要材料，通过将成股的碳纤维丝1绞合后，采用树脂浸渍，而后采用烘箱固化而成。
