Scope

Main technical content: In order to make the quality of high- and low-voltage complete sets of products in Dalian City safer and more reliable, and to make the process of power distribution equipment busbar fabrication and installation in various enterprises more standardized, regulated, and formalized, the Dalian Electrical Quality Technology Association and Dalian Xincheng Electrical Control Co., Ltd. took the lead in organizing multiple member units to research and formulate the group standard "Power Distribution Equipment Busbar Fabrication and Installation Process". The technical features of this standard are formed through practice and in-depth research: (1) Scope of the standard: "Power Distribution Equipment Busbar Fabrication and Installation Process" specifies the equipment, tools, materials, process preparation, busbar selection, process flow, copper strip fabrication process, busbar compression process, busbar phase sequence requirements, soft busbar (BVR) fabrication process, busbar installation requirements, inspection, and special requirements for the fabrication and installation of busbars in high- and low-voltage complete sets of equipment in Dalian City. (2) Principles of construction: 1. Applicability: Applicable to the busbar fabrication and installation process of high- and low-voltage complete sets of equipment in Dalian City's high- and low-voltage complete sets of equipment production industry. 2. Forward-looking: Track social development and technological progress and be moderately forward-looking. 3. Relevance: The preparation of this standard refers to the relevant provisions of GB/T 1.1-2009 "Standardization Work Guidelines - Part 1: Structure and Preparation of Standards". This standard is one of the series of group standards in Dalian's electrical industry. The structure, chapter and article numbering, preparation principles, and definitions and terms used in this standard are unified. 4. Openness: The standard system is ope
