摘　　要：电缆截面的选择是建筑工程供配电设计中的重要内容之一,电缆截面选择的合理与否,直接影响到低压配电系统的安全可靠运行以及初期的投资成本。在大型公共建筑设计中,大多数情况下低压配电电缆截面按载流量选择即可满足要求,对于一些特殊情况必须通过校验计算来确定电缆截面。The selection of cable section is one of the important contents in power supply and distribution design of construction engineering.The reasonable selection of cable section directly affects the safe and reliable operation of lowvoltage distribution system and the initial investment cost.In the design of large-scale public buildings,in most cases,the section of low-voltage distribution cable can meet the requirements according to the current carrying capacity of cable.For some special cases,the section of cable must be determined by verification calculation.
