**课程名称：** 电气现场安装 (Electrical On Site Installations) **课程概述：** 本课程旨在教授学员在项目执行阶段进行电气现场安装的知识。课程将详细介绍电气安装的三个主要阶段： **首次安装 (First Fix Installation)**、**二次安装 (Second Fix Installation)** 和 **三次安装 (Third Fix Installation)**。 * **首次安装：** 重点讲解各类线槽（PVC、金属和柔性类型）的安装方法，包括嵌入混凝土楼板、墙壁和天花板中的安装。同时，还将介绍电缆桥架和线槽的安装及其不同用途。 * **二次安装：** 涵盖在导管内穿线的技巧，强调导管填充率的计算和考量，并详细解释其重要性。此外，还将讲解配电盘、配电箱的安装，以及电线的连接（端接）方法，包括电线如何布放到配电盘，以及电线整理和端接的工艺。 * **电缆和电线测试：** 本部分将指导学员如何使用绝缘电阻测试仪 (Megger) 来测试电缆和电线。通过实际施工现场的视频演示，学员将学习如何进行绝缘测试，以确保在项目通电前电缆和电线的质量。 * **三次安装：** 在前三个阶段完成后，本章将教授如何安装灯具和电源插座，完成墙壁和天花板的电气安装，为项目的最终通电和运行做好准备。 本课程提供以实践为导向的学习，帮助学员掌握电气现场安装的各项技能。
This course is dedicated for students who want to acquire knowledge on how electrical installations are done on site during execution stages. In fact, this course shows how electrical 1st, 2nd and 3rd fix must be installed. In chapter 1 (First Fix Installation), you will learn how containments such as PVC, metallic and flexible types of conduits are installed either embedded inside concrete slab or in different types of walls and ceilings. Moreover, you will learn how cable trays and trunks are installed explaining their different uses. In chapter 2, and as part of the Second Fix Installation, you will learn how wires must be pulled inside conduits. Pulling of wires must be done in consideration of conduit fill ratio that must be calculated before pulling wires which will be explained in detail in this chapter. Following the second fix chapter, you will come across the Panels, DB Installation and Wire Termination chapter which will show you how distribution boards and capacitor banks are installed. In addition to that, you will be able to know how wires are pulled to the panels and how dressing and termination is done. By reaching this stage of the course, the Cable and Wire Testing chapter will guide you on how to test cables and wires using the Megger testing device. In particular, this chapter will show you practically how to perform the Megger (Insulation) test of cables and wires using the megger device through real videos performed during site execution stage to ensure the quality of cables and wires before energizing the project. In the last chapter of this course (Third Fix Installation), and after the first, second and testing stages are explained, you will learn how light fixtures and power sockets are installed in ceilings and walls to finalize the electrical installations before the energization and operation of the project.
