耐热合金-钢芯铝合金绞线

发布时间:2018-03-21 点击量:1988

一、相关结构
        钢芯铝绞线是由铝线和钢线绞合而成的,适用于架空输电线路用。

它内部是钢“芯”,外部是用铝线通过绞合方式缠绕在钢芯周围;钢芯主要起增加强度的作用,铝绞线主要起传送电能的作用;
二、相关型号
       钢芯铝绞线的型号分为:JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A
其中:G1A或G1B指的是普通强度钢线。
G2A或G2B 指的是高强度钢线。
G3A指的是特高强度钢线。
型号差异:以JL/G1A-240/30型钢芯铝绞线为例。
在国标(GB/T1179-2008)中以目前的JL/G1A-240/30表示;
在国标(GB/T1179-1983)中以LGJ-240/30表示。
三、主要应用
       对高电压的输电线路,由于线路的路径有限,又不可能在一个路径上架多条线路,人们想出了采用一个路径,一套铁塔,挂多条导线,即一条线路相当于架了多条线路的方法;对500KV的输电线路,我国大多采用挂四条导线的方式,这种架线的方式称为同塔并架。
四、相关优点
      钢芯铝绞线具有结构简单、架设与维护方便、线路造价低、传输容量大、又利于跨越江河和山谷等特殊地理条件的敷设、具有良好的导电性能和足够的机械强度、抗拉强度大、塔杆距离可放大等特点。因此广泛应用于各种电压等级的架空输配电线路中。
五、技术条件
      1000平方毫米钢芯铝绞线技术将依托宁东—山东±660千伏直流输电工程开展项目实施。公司开展一系列科研工作,综合考虑电磁环境、机械性能、杆塔荷载、经济性等因素,认为在宁东—山东工程中采用1000平方毫米钢芯铝绞线,具有多方面优势,可减少工程本体投资、降低运营成本,是开展“两型三新”输电线路建设,实施资产全寿命周期管理,推动资源节约型、环境友好型社会建设的具体体现。
