 &Nbsp; Wire and cable are important industrial products related to the national economy and people's livelihood. In recent years, the national market supervision system has continued to carry out special rectification of wire and cable production enterprises. The industry order has become increasingly standardized, and the quality level has steadily improved. However, there are still outstanding issues of substandard products in the circulation field, important indicators such as conductor resistance that do not meet standard requirements, and problems such as cutting corners to produce "discounted" cables. In order to further promote the sustained and healthy development of the wire and cable industry and ensure the safety and stability of people's production and life, the State Administration of Market Regulation has decided to focus on key areas, varieties, and issues with prominent quality issues in wire and cable products, and carry out the special action of "joint inspection, joint crackdown, and joint governance" on wire and cable quality and safety
