ACCC(复合芯铝绞线)导线第一部分 ACCC导线性能及结构参数新系列ACCC（复合芯铝绞线）导线，在容量增加一倍的同时，显著地提高了我国电网的安全性和可靠性。

ACCC导线图片复合技术最先应用于航天领域，CTC公司利用这种专利和成本有效的先进复合技术，开发了新一代的电力电缆，应对电力输变电行业提出的挑战。

当前电力行业挑战：自从19世纪晚期输变电线路首次出现后，电力技术进步缓慢。

用电设备发展需求迅猛。

电力成为全国的瓶颈问题。

在用电高峰时段，输电线路传输的容量远远不能满足人们对电力的需求。

传输容量的限制给国家造成严重的损失。

历史上曾经采用增加线路允许从远处的发电机输入电力来减轻电力不足的问题上。

然而，在今天的环境下通过安装新的传输塔和电线杆是行不通的。

多年的努力和百万美元的投入以求得优先通行权,结果毫无进展。

而更新现有结构以采用较大规格更重的电缆费用太高，令人不敢问津。

直到今天，找到对此问题的解决方案比较困难实施更困难。

特别是在炎热的夏天，由于空调器的使用，停电时有发生。

今天尽管发电机能够发出要求的电力，但是电力线路经常不能传输较高的负载.当电力公司能够发现线路过载时，必须断开它们. 当不能发现线路过载时，线路过热造成导线内部金属芯下垂。

当导线下垂时，它极有可能对下面的建筑物或树木发生短路，甚至导线落到地面。

运行中的ACCC导线电力行业的革新解决途径：CTC公司已经设计试验了新一代的复合芯铝绞线，它由轻型的复合芯、外层缠绕高性能的梯形成型铝线组成。

与常规的钢芯铝绞线相比，在相同的外径时，复合芯铝绞线外层允许缠绕超过28%的导电铝线。

成品重量与常规的钢芯铝绞线相似，它能够利用现有线路结构而不需改造。

复合芯铝绞线（ACCC），作为新型导线，能够传输钢芯铝绞线两倍的电流。

CTC公司生产的复合芯，经过许多独立实验室的试验，使用专利的压延工艺进行制造。

许多预拉伸的玻璃和碳纤维用高性能的热固性树脂系统予以浸渍，然后通过加热模迅速固化成形。

式中：L—试样的总长度，m；
N—试样的根数，根；

式中：n—试样的根数，即是公式1中的n；
V—按试样类别确定的每米成束电线电缆试样所含非金属材料的总体积，A类取7.0L/m,B类取3.5L/m,C类取1.5L/m。

即：电线电缆按每米长度所含非金属材料的不同体积分为三种类别：
A类：试样根数应使每米所含的非金属材料的总体积为7L；
B类：试样根数应使每米所含的非金属材料的总体积为3.5L；
C类：试样根数应使每米所含的非金属材料的总体积为1.5L。

对于园形的电线电缆，S=πR2。

其中，R为试样的实测半径，mm。

S m—一根试样横断面中金属材料的总面积，mm2。

其中等于该试样中各芯线导体标称截面积与金属屏蔽或铠装层截面积之和。

对于园形的电线电缆，金属屏蔽或铠装层的截面积用（d O-d i）计算，其中d o 为该层的实测外径，mm，d i为该层的实测内径，mm。

试样根数n，一根试样的截面积S和金属材料总截面积S m的计算值，其小数后为0.5及以上时取1,小于0.5时应舍弃。
