1. Special Insulating Materials Cross-linked heat-shrink insulation is typically used. Busbar trunking insulation is flame-retardant, flexible, long-lasting, and easy to install. In the late 1990s, air-shrink tubing began to gain popularity; this new type of insulating shrink material expands and softens after being treated with a special solvent. Once applied over the conductor, as the solvent evaporates, the sleeve automatically shrinks, securely holding the conductor in place. The ubiquitous presence of air ensures that the sleeve contracts uniformly in all directions. Siemens busbars do not require heating or baking, nor do they necessitate specialized technical personnel or complex tools—only a ruler and scissors are needed, which helps reduce labor costs and the investment in heating equipment.

2. High-strength housing structure
Busbar trunking The connecting cables are sealed within the housing; therefore, the stringent requirements for the housing structure primarily manifest in two aspects.
(1) The specially shaped steel plate is formed by roller pressing to create an integral, cost-effective structure with high mechanical strength and stiffness, while maintaining a compact footprint. The shell can be assembled from interconnected components using either welding or bolted connections, ensuring the electrical insulation of the bolted joints.
(2) Small current intensity, high-density structure, fixed length, capable of withstanding relatively high rated values, as well as short-term current surges and the rated peak thermal stress and electrical stress induced by current.
3. Reliable protective measures
(1) Connect to Busbar trunking The forming device provides the following reliable protection: the unit enclosure is electrically well connected to the grounding terminal, and the connection resistance between any unpainted points and the grounding terminal does not exceed 0.1 ohm.
(2) Each unit of the Siemens busbar shall be equipped with a grounding terminal. The grounding terminal shall be brazed to copper at an easily accessible grounding location and shall be clearly marked with a durable grounding symbol.
(3) When compartment and busbar trunking units are connectable, safe measures to prevent electric shock must be in place. In other words, the electrical conductors must be disconnected before the protective working circuit can be de-energized; prior to energizing the conductors, a connection-based protective circuit design must be established.
(4) 50% capacity ground bus.

Social Responsibility Report of Zhenjiang Ximen Busbar Co., Ltd. (Fiscal Year 2023)
This report is the first Corporate Social Responsibility Report published by Zhenjiang Siemens Busbar Co., Ltd. (or “the Company” or “we”), disclosing our management practices, initiatives, and outcomes in the areas of technological innovation, environmental stewardship, social responsibility, and corporate governance. The reporting period covered by this document is from January 1, 2023, to December 31, 2023; however, certain sections extend beyond this time frame.
Recently, the XL-IIS compact busbar trunking system from Siemens Busbar Co., Ltd. in Zhenjiang was recognized by the Data Center Branch of the China Computer Users Association as the “2023 Data Center Innovation Product,” while the XL-III compact busbar trunking system was awarded the “2023 Data Center Customer Satisfaction Product.” These accolades underscore Siemens Busbar’s innovative technologies and high-quality services in the data center sector.
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.
