设备线夹重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。因惯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。根据安装办法和构造形式的不同，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等表达合用导线组合偏高：120...300等表达合用导线标称截面积附加字母的意义为：A－0°B－30°B1－45°C－90°设备线夹对导线的握力不不大于导线计算拉断力的10%，但螺栓型合用导线直径不不大于49mm，为不不大于3%。线夹的直线电阻不不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）型号合用导线重要尺寸(mm)重量(kg)ABDL1L2SYG-50ALGJ-5040186060SYG-70ALGJ-7040227080SYG-95ALGJ-9540268080SYG-120ALGJ-12050268085SYG-150ALGJ-15050328085SYG-185ALGJ-18550328085SYG-120/7ALGJ-120/750268080SYG-150/8ALGJ-150/850308090SYG-150/20ALGJ-150/2050308090SYG-185/10ALGJ-185/1050328090SYG-185/25ALGJ-185/2550328090SYG-240/30ALGJ-240/30503680100SYG-300/15ALGJ-300/156340100110SYG-300/20ALGJ-300/206340100110SYG-300/25ALGJ-300/256340100110SYG-300/40ALGJ-300/406345100110SYG-400/20ALGJ-400/206345100120SYG-400/25ALGJ-400/256345100120SYG-400/35ALGJ-400/356345100120SYG-400/50ALGJ-400/506345100120SYG-400ALGJ-40012045120150SYG-500/35ALGJ-500805280130SYG-500/45ALGJ-500/45805280130SYG-500/65ALGJ-500/65805280130SYG-630/45ALGJ-630/4510060100150SYG-630/55ALGJ-630/5510060100150SYG-630/80ALGJ-630/8010060100150SYG-800/55ALGJ-800/5512565170170SYG-800/70ALGJ-800/7012565170170SYG-800/100ALGJ-800/10012565170170SYG铜铝过渡设备线夹（压接型B类）型号合用导线重要尺寸(mm)重量(kg)ABDL1L2SYG-50BLGJ-5040186060SYG-70BLGJ-7040227080SYG-95BLGJ-9540268080SYG-120BLGJ-12050268085SYG-150BLGJ-15050329085SYG-185BLGJ-18550329085SYG-120/7BLGJ-120/750269080SYG-150/8BLGJ-150/850309080SYG-150/20BLGJ-150/2050309080SYG-185/10BLGJ-185/1050329080SYG-185/25BLGJ-185/2550329080SYG-240/30BLGJ-240/30503610080SYG-300/15BLGJ-300/156340110100SYG-300/20BLGJ-300/206340110100SYG-300/25BLGJ-300/256340110100SYG-300/40BLGJ-300/406340110100SYG-400/20BLGJ-400/206345120100SYG-400/25BLGJ-400/256345120100SYG-400/35BLGJ-400/356345120100SYG-400/50BLGJ-400/506345120100SYG-400BLGJ-40012045150120SYG-500/35BLGJ-500805213080SYG-500/45BLGJ-500/45805213080SYG-500/65BLGJ-500/65805213080SYG-630/45BLGJ-630/4510060150100SYG-630/55BLGJ-630/5510060150100SYG-630/80BLGJ-630/8010060150100SYG-700/70BLGJ-700/7010060170105SYG-800/55BLGJ-800/5512565175120SYG-800/70BLGJ-800/7012565175120SYG-800/100BLGJ-800/10012565175120SY系列铝设备线夹（压接型A类）型号Type合用导线Conductor重要尺寸Dimensions(mm)重量(kg)ABDL1L2SY-35/6ALGJ-35/6308166060SY-50/8ALGJ-50/8308186060SY-70/10ALGJ-70/10408227060SY-95/15ALGJ-95/154010268060SY-120/7ALGJ-120/75010268080SY-150/8ALGJ-150/85010309080SY-150/20ALGJ-150/205010309080SY-185/10ALGJ-185/105012329080SY-185/25ALGJ-185/255012329080SY-240/30ALGJ-240/3050123610080SY-300/15ALGJ-300/15631640110100SY-300/20ALGJ-300/20631640110100SY-300/25ALGJ-300/25631640110100SY-300/40ALGJ-300/40631640110100SY-400/20ALGJ-400/20631645120100SY-400/25ALGJ-400/25631645120100SY-400/35ALGJ-400/35631645120100SY-400/50ALGJ-400/50631645120100SY-400ALGJ-4001201445120120SY-400A1LGJ-4001201445120150SY-500/35ALGJ-500/358016...
