耐张线夹

Strain clamp

螺栓型耐张线夹用于钢芯铝绞线和铝绞线时，可在导线外加缠铝包带或护线条，其适用导线外径包括包缠物。
As the bolt type strain clamp is used to AACand ACSR.the conductor may be wound by aluminium tape or preformed armour rods for
protecting.
耐张线夹主要用于在架空电力线路中固定导线和避通过连接金具与耐张绝缘子相连：或将避雷线与杆塔相连。按结构和安装方法的不同分为螺栓型、压缩型
和楔型三大类，压缩型又分液压和爆压两种。 D
产品型号中字母数字的意义为：N- 耐张线夹；L- 螺栓型 ；D- 倒装式； Y- 液压型； B- 爆压型。
数字表示适用导线组合号 ( 或适用绞线标称截面。分子表示铝截面；分母表示钢截面 )
附加字母：A- 引流 0°； B- 引流，30°
螺栓型耐张线夹的曲率半径小于被安装导线直径的 8 倍。耐张线夹导线的最小握力与导线计算拉断力的百分比如下表： 线路金具
Strain clamps are used to fix condcutor and ground wire through insulators or link fitting to tower arms or substation structures， according to the clamp
construction and mounting way，the clamps include three types as compression type and bolt type wedge type，The compression type includes
hydraulic type and explosive type.
The meaning of letter & Arabic figure in the catalog are shown as follow. N-strain clamp L- bolt type D-inverse mounting Y-hydraulic type B-explosive
type The figures mean the of assembled leads which apply to each other numbers.
Additional letter: A-jumper 0。 B-jumper 30°
The radius of curvature is more than eight fold diameter of the suitable conductor，the percentage minimum slip strength of clamp to rated ultimate
strength of conductor is shown in the following table.
