Traditional distribution cabinets rely on indicator or analog meters, which can only monitor a limited set of cabinet parameters and are sufficient for basic requirements. In contrast, modern distribution cabinets employ highly integrated, stable computer boards that support comprehensive monitoring of various operational parameters via an HMI-integrated display, thereby reducing the space occupied by the cabinet and increasing its utilization efficiency.
Tradition Power distribution The cabinet employs either indicator-type or digital display instruments, which can only monitor a limited set of distribution-cabinet parameters but are sufficient to meet basic requirements. The distribution cabinet is equipped with a highly integrated, high-stability computer board that supports a wide range of operational parameters for the comprehensive monitoring system. By integrating these parameters on an HMI-based display screen, space occupancy within the cabinet is reduced, thereby increasing its utilization rate.
Secondly, the existing Power distribution A standard cabinet is solely responsible for power distribution management, allocating power to loads. In contrast, a precision distribution cabinet not only provides power distribution management but also incorporates operational and security management functions, thereby enhancing the reliability of the entire power distribution system and reducing risks. Existing distribution cabinets typically have a limited number of circuits and occupy a large footprint. Precision distribution boxes, on the other hand, employ high-precision, highly integrated modules that increase the cabinet’s overall volume while supporting more circuits, thus minimizing the required floor space.
Functions of the distribution cabinet:
1. Comprehensive Monitoring System
Accurately measures comprehensive electrical parameters to enable effective management and risk early warning for the power supply system. Monitors electrical parameters on up to 84 feeder circuits and the primary power input line, providing complete real-time data on current, power, and harmonics for both the main power input and each branch circuit. When paired with a leakage current acquisition device, the precision distribution cabinet delivers online leakage monitoring; when combined with temperature sensor accessories, it also provides real-time temperature monitoring of hot-spot cabinets, thereby enhancing the safety of the data center’s power supply system.
2. Advanced Alarm Function
Multi-level alarm settings help prevent potential faults, enabling proactive response. For parameters such as overload, overvoltage, undervoltage, three-phase imbalance, overheating of isolating switches, and lightning protection failures, the circuit can be integrated with multi-level alarm display devices or dedicated gateways to promptly notify administrators of alarm information via visual displays, audible alarms, SMS messages, and email.
3. High precision, wide coverage
Provides accurate measurement data while meeting a wide range of requirements. To monitor the power supplies of rack-mounted and blade servers, a variety of feeder CT range options are available to minimize measurement error. It also supports circuit measurements for branch circuits with currents up to 100 A.
4. High Performance, High Integration
Outstanding performance and highly integrated design ensure more stable and secure equipment operation. With centralized branch metering and a high degree of product integration, the power-monitoring and data-acquisition unit measures only 214 × 168 mm, allowing for flexible installation in relatively confined spaces. This significantly enhances cabinet-mounted installation capabilities and overall operational stability, while also facilitating subsequent user maintenance.
5. Enhance operational and power management efficiency
Enables users to promptly monitor load status and implement monitoring and alerting for each PDU power supply; multi-level alarm configurations help prevent potential power failures, allowing users to identify safety risks early and thereby prevent Power distribution Risk. Achieve comprehensive and accurate power distribution with alarm functionality to reduce partial power outages caused by user misoperation.

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.
