设备线夹说明.docx

1、设备线夹说明设备线夹设备线夹主要用于变电所母线引下线与电气设备（如变压器、断路器、隔离开关、互感器）的出线端子接续。因常用电气设备的出线端子为铜质和铝质两类，而母线引出线分为铝绞线或钢芯铝绞线，故设备线夹从材质上分为铝设备线夹和铜铝过渡设备线夹两个系列。根据安装方法和结构形式的不同，设备线夹分螺栓型、压缩两种类型。每种型式的线夹又按引下线与安装电气设备端子所成角的不同分为0、45、90三种。产品型号中字母和数字的意义为：S设备线夹、双Y压缩型L螺栓型G过渡（铜、铝过渡）数字-1、2等表示适用导线组合偏高：120.300等表示适用导线标称截面积附加字母的意义为：A0B30B145C90设备线夹对

2、导线的握力不小于导线计算拉断力的10%，但螺栓型适用导线直径大于49mm，为不小于3%。线夹的直线电阻不大于等长导线的电阻，载流温升低于导线的温升。SYG铜铝过渡设备线夹（压接型A类）型号适用导线主要尺寸(mm)重量(kg)ABDL1L2SYG-50ALGJ-50405.01860600.2SYG-70ALGJ-70405.02270800.3SYG-95ALGJ-95405.02680800.3SYG-120ALGJ-120508.02680850.5SYG-150ALGJ-150508.03280850.6SYG-185ALGJ-185508.03280850.5SYG-120/7ALGJ
