ABSTRACT

High and low voltage distribution equipment is the core hub of the user side power system, and its installation quality directly affects the reliability of power supply, equipment life, and electrical safety. In the current construction of industrial and civil power distribution engineering, common quality problems such as poor terminal crimping, illegal cable laying, and grounding failure are frequently caused by non-standard processes, lack of control, and insufficient personnel skills. These problems can easily lead to equipment heating, insulation breakdown, short circuit power outages, and electrical fires, resulting in significant power losses. This article combines the practice of power distribution room renovation projects, strictly follows the national electrical acceptance specifications and the operating standards of Southern Power Grid, sorts out the manifestations, hazards, and causes of typical quality problems in power distribution installation, and formulates preventive measures from the aspects of process control, inspection standards, environmental protection, and management mechanisms, clarifying key process technical parameters and acceptance indicators. The research results can provide practical reference for quality control of similar distribution installation projects, effectively reduce equipment failures, and improve the level of power supply safety.
