With the continuous upgrading of electric power technology, the socket 118 specification has been widely used in many fields such as home appliances, electric power engineering, lighting engineering, logistics equipment and medical equipment. In the Pearl River Delta region, a more mature product culture has been formed, involving various advanced integrated circuits, high-precision processing, high-reliability assembly and testing technologies, making it one of the most popular specifications in the international market.
