摘要
结合NEC和IEC相关规范,从并联导体的使用条件、允许持续载流量和电缆的配电保护措施三方面,对国标中并联电缆的相关要求进行了深入探讨,使广大电气设计人员在低压配电设计中能够正确理解规范要求,并合理选用并联电缆。
The application requirement, ampacity calculation and power distribution protection were discussed, which should be considered in choosing parallel cables. The principles of using parallel cables in GB, NEC and IEC were compared and summarized. It is useful for electrical designers in understanding standards and choosing parallel cables.
