螺栓型鋁合金耐張線夾(NLL) aluminum alloy strain clamp (bolt type)

 

產(chǎn)品詳細:

耐張線夾 strain clamp

耐張線夾主要用于架空電力線路或變電所固定導(dǎo)線和避雷線,并通過連接金具與耐張絕緣子相連,或?qū)⒈芾拙€與杠塔相連。按結(jié)構(gòu)安裝方式的不同分為螺栓式、

壓縮型和楔型三大類,壓縮性又分為分液壓和爆壓兩種

產(chǎn)品型號中字母數(shù)字的意義為:

N-耐張線夾 L-螺栓型 D-倒裝式 B-爆壓型

數(shù)字表示適用導(dǎo)線組合號(或適用鋼絞線標稱截面,分子表示鋁截面,分母表示鋼截面)

附加字母:A-引流0 B-引流30

螺栓型耐張線夾的曲率半徑補小于被安裝導(dǎo)線直徑的8倍。耐張線夾導(dǎo)線的最小握力與導(dǎo)線計算拉斷力的百分比如下表:

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
