Abstract. In recent years, with the rapid development of China's economy and the acceleration of urbanization, the construction industry has also developed rapidly. With the improvement of people's living standard, people have higher and better requirements for their living environment. As a result, people have higher requirements for the construction projects which are closely related to their own lives. Building electrical system is a part of construction project, and low voltage electrical installation technology is the core of building electrical technology. This technology plays an important role in ensuring the safety of electrical engineering and the quality of the whole construction project. Low voltage electrical installation has a great influence on the normal operation of building electrical equipment, and it is a very important link in the construction project. Low voltage electrical installation technology and the procedure is complicated, the quality of the finished directly affects the entire building electrical engineering operation, must be of low voltage electrical installation engineering of comprehensive control to ensure the quality of installation. This article mainly analyzes the low voltage electrical installation technology in building electrical equipment.In recent years, the development of China's construction industry is relatively rapid, in city construction, we can see is the construction of the edifice, however, with the construction industry is becoming increasingly prosperous, we have heard a lot about building the bad rumors, such as tofu engineering etc.. Therefore, improving the quality of construction is particularly important. Electrical installation in building engineering is one of the important factors that affect the quality of building. Therefore, we should improve the electrical installation technology, especially the use of a wide range of low-voltage electrical installation technology, so as to improve the quality of the entire construction project, to meet the requirements of the construction industry.
Features of Low Voltage Electrical Installation Technology
In the installation of building electrical process, will be affected by many external factors, thereby affecting its quality, there are certain hidden dangers. This requires that the installation engineers in the process of strict checks. Ensure installation quality during engineering implementation. The low voltage electrical installation works with long construction schedule, complex installation process and complicated process, which causes many external factors to be involved in the process.The quality of construction is difficult to guarantee. Before the construction, the grounding grid and pipeline laying should be adequate, and then enter the equipment test stage. At the end of all projects, the staff to debug the system to the best state, by the relevant departments testing acceptance.
Construction Project Low Voltage Electrical Debugging
When the low voltage electrical installation of building construction project is finished, it is necessary to check the operation of the components in the low voltage electrical installation project to ensure the effectiveness of the installation of low voltage electrical equipment. To be specific, the current and voltage of the set of distribution (control) equipment should be in normal condition. The motor should be electrified to observe its steering and mechanical rotation is normal, and no-load

therefore, in the construction process, we must uphold a rigorous and scientific work attitude, strict control of the quality of the project. Improve the quality of construction, and thus improve people's quality of life. This requires more attention to the quality of the project supervision work, strengthen the training of relevant personnel, supervision and inspection of the establishment of quality supervision team of practical engineering project quality, so as to promote the sustainable development and use of building electrical low-voltage electrical.
