摘要
电缆是电气设计、施工中常用材料。设计、施工、监理人员对电缆规格比较熟悉,但对电缆截面了解较少。一般采用经验确定电缆桥架截面尺寸,但是对于其是否满足填充率,并没有一个量的概念。为此,通过分析推导,提出了一个根据电缆规格计算电缆截面的简便方法。
Cables are commonly used in electrical design and construction.Design,construction,and supervision personnel are more familiar with cable specifications,but have less understanding of cable cross-section.Generally,experience is used to determine the cross-sectional size of cable trays.However,there is no concept of quantity as to whether the fill rate is satisfied.Therefore,through analytical derivation,a convenient method for calculating cable cross-section according to cable specifications is proposed.
