的导线横截面的选择通常基于所述热导体,电压损失,机械强度等 根据经验,低压电源线,因为负载电流的大时,它通常是按加热条件被选择的横截面,然后检查电压损失和机械强度; 因为它的高级别要求低压照明线,可以按允许电压损耗条件选择信息,然后检查的机械强度和热条件。
导体材料的选择中,由于铝导体具有重量轻,无疑是电缆的优选架空电线绝缘。从由于抗氧化剂铝合金导体和耐腐蚀性的安全要求开始比铜导体显著降低,在高温应用中,易燃易爆场所,潮湿的地方和铝的腐蚀的地方(如换热站泵房),人聚集较多的地方(如活动中心,商业属于行业人才云集更多的地方),一个重要的图书馆,电脑室,重要仓库(如消防控制室,弱电总机房,控制室)。移动设备或过度振动的地方(如发电机房)等,不应该使用铝电缆。
