螺栓型铝合金耐张线夹(NLL) aluminum alloy strain clamp (bolt type)

 

产品详细:

耐张线夹 strain clamp

耐张线夹主要用于架空电力线路或变电所固定导线和避雷线,并通过连接金具与耐张绝缘子相连,或将避雷线与杠塔相连。按结构安装方式的不同分为螺栓式、

压缩型和楔型三大类,压缩性又分为分液压和爆压两种

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 B-爆压型

数字表示适用导线组合号(或适用钢绞线标称截面,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补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:

Strain clamps are used to fix condcutor and ground wire through insulators or link fitting to tower arms or substation structures.in according to the clamps

construction and mounting way the clamps include two types as compression type and bolt type,the compression type include hydraulic and explosive type

The meaning of the letter & arabic figure in the catalog are shown as follow:

N-strain clamp L-bplt 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 35 .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 os shown in the following table
