预绞式拉线耐张线夹

预绞式导线耐张线夹(以下简称导线耐张线夹)，是一种拉力强又操作简单的耐张线夹，可以用在主要和分支配
电线路的裸导线和架空绝缘导线上，它的拉力优于目前国内常用的耐张线夹，因此，可替代目前在线路上常用的包
括螺栓型在内的耐张线夹。

导线耐张线夹的结构简单，其预绞丝双腿绞合形成空管，后部为预成型的绞环。

预绞丝双腿形成的空管缠绕在
导线上时就可以产生极强的握紧力，而绞环用以固定在绝缘子上。

独特的原理和结构使该种导线耐张线夹具有独特
的性能和鲜明的特点。

预绞丝ADSS光缆耐张线夹
用途：架空输电线路中转角杆塔需要使用耐张线夹来连接固定光缆，ADSS耐张线夹有足够
的拉力来将耐张线夹固定在档距100-1000米之间的线路杆塔上面，根据光缆参数的需求，耐
张线夹也分为大、中、小三种不同强度的耐张线夹金具，与架空线路用预绞式金具结构基本
相同，用于终端铁塔和线路中间耐张铁塔上面，它能均匀地分配径向压力，并传递轴向压力，在保证不损伤光缆的前提下提供安全可靠的握紧力。

包钢外绞丝、螺丝、螺母、闭口哨等（用户可根据设计要求配置选购其它的连接件）。

配置须知：
1、根据ADSS光缆的极限抗拉强度、运行档距和外径来选择合适型号的耐张线夹。

2、应同时提供ADSS光缆的相关参数：光缆的最大允许张力、每日运行张力和抗侧压强度。

3、数量配置：1套/终端杆塔；2套/耐张杆塔、光缆接续杆塔或转角＞25°。
