《电气装置安装工程施工及验收规范》(GBJ232—82)第十三篇第3·4·1条规定塑料护套线不得直接埋入抹灰层内暗配敷设。根据工作实践,我认为有必要将这条文取消。《规范》编制说明解释,这样的规定主要原因有二:一是从墙面钉入铁件会损坏导线而漏电,不安全;二是不便于维修、更换 Article 13, 4 and 1 of Part 13 of the “Electrical Installation Installation Construction and Acceptance Code” (GBJ232-82) stipulates that the plastic sheathed wire shall not be buried directly in the plastering layer for concealed laying. According to work practices, I think it is necessary to cancel this article. The specification of the “norm” explains that there are two main reasons for such a requirement: First, nailing iron into the wall will damage the wire and cause leakage; it is not safe; second, it is not easy to maintain and replace.
