With the development of future technology, energy technology is integrated with automation and software technology, so that switchgear with high reliability and high performance is required. As an important part of the distribution network, low-voltage switchgear is difficult to expand or combined transform in engineering applications because there are wide variety of low-voltage cabinet types on the market, and each cabinet from the different manufacturer has its own characteristics in appearance and structural form. For various reasons, State Grid began to promote the standardization of low-voltage switchgear. The standardization design can not only improve the overall quality of low-voltage distribution cabinets, but also improve user satisfaction.
