耐张线夹，拉力线夹，死端线夹

耐张线夹（拉力线夹、死端线夹）是指用于固定电线、承受电线张力以及将电线悬挂在耐张线或塔上的金属固定装置。

耐张线夹根据其结构和安装条件不同，大致可分为两大类。第一类：耐张线夹要承受导线或防雷线的全部拉力，线夹夹紧力应不小于所安装导线或防雷线额定拉力的90%，但不作为导线使用。此类线夹在导线安装完毕后，可拆除单独使用。此类线夹包括螺栓型耐张线夹和楔型耐张线夹。第二类：耐张线夹除承受导线或防雷线的全部拉力外，还作为导线使用。因此，此类线夹一旦安装完毕，就不能拆卸，又称死线夹。

Tension clamps are used for corner, splice, and terminal connections. Spiral aluminum clad steel wire has extremely strong tensile strength, no concentrated stress, and plays a protective and auxiliary role in vibration reduction for optical cables. The complete set of fiber optic cable tension fittings includes: tension pre twisted wire and matching connection fittings. The grip strength of the cable clamp is not less than 95% of the rated tensile strength of the optical cable, making installation convenient and fast, and reducing construction costs. Suitable for ADSS optical cable lines with a span of ≤ 100 meters and a line angle of<25 °

耐张线夹用于将导线或避雷针固定于非线性塔的耐张绝缘子串上，起锚固作用，也用于固定拉线塔的耐张线。
