摘　　要：从工程设计的角度分析了矿物绝缘电缆在适用原则、产品选型、安装敷设等方面的若干问题,提出了选用矿物绝缘电缆应以满足消防配电线路持续供电时间为核心的观点,并阐述了矿物绝缘电缆铜护套用作PE线在技术规范、截面积要求、热稳定性校验等方面的合理性,可为类似项目提供参考。By analyzing some issues about the application principle,product selection and installation of mineral insulated cable from the engineering design angle,the idea was put forward.The selection of mineral insulated cable should match the duration of power supply on fire power distribution lines.Further,the rationality of copper sheath used as PE wire in code,cross-sectional area requirement,thermal stability check is expounded.It can provide reference for similar projects.
