LGJ导线参数表
LGJ导线参数表LGJ 导线,全称为钢芯铝绞线,是在电力输送领域中广泛应用的一种导线类型。
它由多股铝线绞合在钢芯外层构成,兼具了铝的良好导电性和钢的高强度特性。
为了让大家对 LGJ 导线有更全面、深入的了解,下面为大家详细介绍 LGJ 导线的各项参数。
一、LGJ 导线的型号LGJ 导线的型号通常由字母和数字组成,其中“LGJ”表示钢芯铝绞线,后面的数字则表示导线的标称截面积。
例如,LGJ-185 表示该导线的标称截面积为 185 平方毫米。
常见的 LGJ 导线型号还有 LGJ-95、LGJ-120、LGJ-240 等。
二、LGJ 导线的结构参数1、铝绞线部分铝绞线部分由多股铝线绞合而成。
股数的多少和每股的直径会根据导线的标称截面积而有所不同。
一般来说,标称截面积越大,铝绞线的股数越多,每股直径也越大。
2、钢芯部分钢芯通常由多股高强度钢丝绞合而成,其作用是增加导线的机械强度。
钢芯的股数和每股直径也与导线的标称截面积相关。
三、LGJ 导线的电气参数1、直流电阻LGJ 导线的直流电阻是其重要的电气参数之一。
直流电阻的大小直接影响到导线在输电过程中的电能损耗。
一般来说,导线的标称截面积越大,其直流电阻越小。
2、载流量载流量是指 LGJ 导线在一定环境条件下能够安全承载的最大电流值。
载流量的大小受到导线的材质、截面积、敷设方式、环境温度等多种因素的影响。
在实际应用中,需要根据具体情况对载流量进行计算和校验,以确保导线能够满足输电需求,同时不会因过载而发生故障。
四、LGJ 导线的机械参数1、拉断力LGJ 导线的拉断力是指导线在受到拉伸作用时所能承受的最大拉力。
拉断力的大小与导线的结构、材质以及标称截面积密切相关。
在设计输电线路时,需要根据线路的档距、气象条件等因素,合理选择具有足够拉断力的 LGJ 导线,以确保线路的安全运行。
2、重量LGJ 导线的重量也是一个重要的机械参数。
重量的大小会影响到线路的杆塔设计、施工安装以及运行维护等方面。
