电气安装是建筑工程施工后期的一项重要工作。在施工前,首先需要为后期电缆和线路进行孔洞预留和管路预埋工作。然后进行变电设备支架的固定和变电设备的安装,同时为电缆进行桥架安装。安装完毕后,需要在预先布设的管道、孔洞内进行线路穿线以及导线、电缆的连接工作,需要注意导线和电缆的防火防潮。最后需要按照设计要求进行照明设备的安装,以及相关开关、插座的安装工作,尤其注意的是要做好防雷和接地工作以保障安全。在设备全部安装完毕后,要对供电、控制、照明等设备进行安全可靠性测试,合格后才可交付。
Electrical installation is an important part of the construction of the late construction. Before construction, first of all need to be reserved for future cables and lines and pipeline buried work. Then the substation equipment bracket and substation equipment installation, at the same time for the cable bridge installation. After installation, it is necessary to thread the wires and cables in pre-arranged pipes and holes, and pay attention to the protection against fire and moisture of wires and cables. Finally need to follow the design requirements for lighting equipment installation, and related switches, sockets installation work, with particular attention is to do lightning protection and grounding work to ensure safety. After all the equipment has been installed, it is necessary to test the safety and reliability of the equipment such as power supply, control and lighting before it can be delivered.
