摘要
通过设计案例和标准编制组复函对GB 51348-2019《民用建筑电气设计标准》第8.1.6条的理解展开探讨,提出:带铜护套的矿物绝缘类不燃性电缆可直接明敷,不宜采用金属槽盒布线,宜采用金属梯架布线。
The understanding of Article 8.1.6 of Standard for Electral Design of Civil Buildings(GB 51348-2019)is discussed through the design case and reply letter from the specification drafting group.It is proposed that the mineral insulated non‑combustible cable with copper sheath can be directly laid,metal trough wiring maynot be adopted,and metal ladder wiring may be adopted.
