Busway originated in the United States, was first put into practical application in Japan, and subsequently spread rapidly across developed countries and regions. So what exactly is a busway? A busway is a trunk-type, tap-off power distribution system designed to carry relatively high currents. It typically consists of a metal enclosure (made of steel or aluminum), conductive elements (copper bars or aluminum busbars), insulating materials, and associated accessories.
Busbar trunking Originating in the United States, it was first put into practical use in Japan and subsequently spread rapidly across developed countries and regions. So what exactly is a busbar trunking system? It is a high-current, trunk-type, tap-off power distribution system typically composed of a metal enclosure (made of steel or aluminum), conductive elements (copper bars or aluminum busbars), insulating materials, and associated accessories.
In recent years, driven by the extensive development of infrastructure, electricity demand has continued to rise, and busbar trunking systems have gradually become the standard power distribution solution for industrial plants, high-rise buildings, commercial complexes, and rail transit systems.
Busbar trunking It is a closed metal enclosure composed of copper or aluminum busbars, used to distribute high power to the various components of a distributed system. In indoor low-voltage power distribution trunking projects, it has increasingly replaced wires and cables. Simply put, a busbar trunking system is a long, rectangular steel box designed to house cables; it is covered from above and serves to enclose the distribution cables (although the main power supply cable does not necessarily have to be a copper busbar, and copper busbars are not permitted to be enclosed).
Because busbars are often very long, the metal enclosure is typically assembled from multiple sections joined together. The joints between each section must be connected using flexible conductors—usually flexible copper strips—and the entire assembly must be properly grounded at the ends to ensure that any leakage current will not pose a risk to human safety. To explain it using technical terminology, Busbar trunking This is precisely because modern high-rise buildings and large industrial workshops require enormous amounts of electrical power, and such applications demand powerful currents on the order of hundreds or even thousands of amperes; therefore, a safe and reliable conductive device must be selected.
Busbar trunking systems are highly efficient power distribution devices, particularly well suited to the rational wiring requirements of high-rise buildings and large industrial facilities. With the advent of modern engineering infrastructure and equipment, electricity consumption across all sectors has increased rapidly, especially in the construction of numerous high-rise buildings and large-scale industrial plants. Traditional cables, as transmission lines, can no longer meet the demands of high-current systems, and the parallel installation of multiple cables introduces significant challenges for on-site installation and connection work. In response, busbar trunking systems have emerged as a new type of power distribution conductor. Compared with conventional cables, they fully demonstrate their advantages in handling high currents. Moreover, thanks to the adoption of advanced technologies and manufacturing processes, the contact resistance and temperature rise at the end connections and branch tap-offs of busbar trunking systems have been substantially reduced. The use of high-quality insulating materials further enhances safety and reliability, thereby improving the overall performance and integrity of the system.

Zhenjiang Ximenzi Hosts a Knowledge Competition
A total of nine teams from various departments took part in this competition. After nearly an hour of intense rivalry, the first-, second-, and third-place awards, as well as the Gold Medalist Award, were ultimately presented.
Zhenjiang Ximenzi Conducts EHS Professional Knowledge and Internal Trainer Training
On December 12, Zhenjiang Siemens invited a professional instructor from Shanghai Qian’an Environmental Protection Company to deliver EHS (Environment, Health, and Safety) expertise training and internal trainer development sessions. More than 20 participants, including heads and supervisors of the Production Department, equipment administrators, and selected frontline employees, attended the training. The curriculum covered mechanical safety safeguards, hazard identification, and risk assessment, with an introduction to practical tools such as energy control and lockout/tagout procedures. During the session, the instructor enhanced trainees’ understanding of how unsafe behaviors lead to accidents by showing short animated videos on behavioral safety. This training marked the first phase of the company’s EHS program; going forward, Zhenjiang Siemens will implement a comprehensive EHS training plan as scheduled to further elevate the company’s EHS management standards.
