With the emergence of modern engineering facilities and equipment, the power consumption of various industries has increased rapidly, especially in the presence of numerous high-rise buildings and large workshops. Traditional cables used as power transmission lines cannot meet the requirements in high-current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the on-site installation and connection. As a new type of distribution cable, the plug-in busway has emerged as a new type of cable. Compared with the traditional cable, it has its advantages in large-current transmission. At the same time, due to the adoption of new technologies and new processes, the busbar is greatly reduced. The contact resistance and temperature rise at the joints at the two ends of the slot and the junction of the splitter port, and the use of high-quality insulating materials in the busway, thereby improving the safety and reliability of the busway and improving the overall system. Nowadays, the main market leaders include General Electric of the United States, Schneider of France and the LS cable system of Korea. With the rapid development of the Asian economy, the competition in the Asian busway market has become increasingly fierce. In the fierce competition, the Korean LS cable system is a leader. The LS cable system currently leads the domestic busway market in Korea, with an annual revenue of 150 billion won (about 870 million yuan), accounting for over 50% of the market.
