Abstract: The implementation of crucial process control is the focus of power transmission and distribution product manufacturing quality.Critical process control requires process quality analysis,and this process quality analysis uses relevant statistical techniques to describe and infer data and information. These methods help to grasp the key process quality status. The system could be improved and upgraded. This paper uses three cases to illustrate the application of statistical process control (SPC), measurement system analysis (MSA) and other methods in the key processes of wire and transformer manufacturing. This paper discusses the application of statistical techniques to improve the manufacturing quality of power transmission and distribution related products. The case application results show that this method improves the physical quality of power transmission and distribution products, reduces quality loss, and descends manufacturing costs.
Key words: electric power transmission and distribution; transformer; wire and cable; key process; process capability; statistical process control; measurement system analysis
