电线电缆的选择和铺设放线的方法
一. 导线种类 说明: 用作电线电缆的导电材料,通常有铜和铝两种。铜材的导电率高,50℃时的电阻系数。铜为0.0206mm2/m,铝为0.035mm2/m;载流量相同时,铝线芯截面约为铜的1.5倍。采用铜线芯损耗比较低,铜材的机械性能优于铝材,延展性好,便于加工和安装。

  用作电线电缆极速炸金花的导电材料,通常有铜和铝两种。铜材的导电率高,50℃时的电阻系数。铜为0.0206Ω·mm2/m,铝为0.035Ω·mm2/m;载流量相同时,铝线芯截面约为铜的1.5倍。采用铜线芯损耗比较低,铜材的机械性能优于铝材,延展性好,便于加工和安装。抗疲劳强度约为铝材的1.7倍。但铝材比重小,在电阻值相同时,铝线芯的质量仅为铜的一半,铝线、缆明显较轻。

  B.无机型是矿物绝缘电缆。它是采用氧化镁作为绝缘材料,铜管作为护套的电缆,国际上称作为MI电缆。在某种意义上是一种真正的耐火电缆,只要火焰温度不超过铜的熔点1083℃,电缆就安然无恙。除了耐火性外,还有较好的耐喷淋及耐机械撞击性能,适用于消防系统的照明、供电及控制系统以及一切需要在火灾中维持通电的线路。它又是一种高温电缆,允许在250℃的高温下,长期正常工作。因此适合在冶金工业中应用,也适合在锅炉装置、玻璃炉窑、高炉等高温环境中使用。
