Basic Information
Scope
Main Technical Content: In recent years, the low-voltage complete equipment industry in Dalian City has developed rapidly. As of now, there are more than 100 low-voltage complete equipment manufacturing enterprises, which has injected strong impetus into the economic development of Dalian City. Due to the fact that low-voltage complete equipment manufacturing adopts national standards equivalent to the IEC international standards (GB7251 series standards), the requirements for product quality are high. At the same time, these products are included in the national mandatory product certification catalog, which imposes even higher requirements on the electrical safety quality of products. Therefore, quality control during the production process of enterprises is particularly important, especially for electrical installation processes, such as the technical requirements for the fabrication and installation of primary and secondary wiring. However, at present, national standards, industry standards, and local standards do not provide specific requirements and regulations for the fabrication and installation of primary and secondary wiring. Each enterprise independently formulates some internal control technical documents to regulate this, resulting in differences in the quality of complete equipment. In order to make the quality of high- and low-voltage complete equipment products in Dalian City safer and more reliable, and to make the primary and secondary wiring fabrication and installation processes in enterprises more standardized and formalized, the Dalian Electrical Quality Technology Association and Dalian Xinheng Electric Control Co., Ltd. took the lead in organizing several member units to research and formulate the group standard "High- and Low-Voltage Complete Equipment Primary and Secondary Wiring System Fabrication and Installation Processes - Part 1: Busbar Fabrication and Installation Processes". The technical features of this standard were formed through
