Key considerations for the application of low-voltage switchgear: In recent years, rapid socio-economic development has led to a substantial increase in demand for low-voltage switchgear; however, various factors have given rise to an ever-growing number of challenges. We would like to offer a friendly reminder that when selecting and deploying high-voltage switchgear, it is essential to choose the appropriate installation environment based on its intended function. If you have any questions or uncertainties, please feel free to call our hotline for expert advice.
Low-voltage switchgear Points to Note in Application
In recent years, with the rapid socio-economic development, the demand for low-voltage switchgear has grown substantially. However, due to various factors, an increasing number of challenges have emerged. We would like to kindly remind you that when selecting and applying high-voltage switchgear, it is essential to choose the appropriate application environment based on its intended function. If you have any questions or uncertainties, please call our hotline for consultation.
1. Low-voltage switchgear shall be installed in locations where the switchgear current needs to be reduced.
2. The motor must be capable of speed variation during normal operation and shall only address the operating environment throughout the entire operational process.
3. During normal operation, the pressure reduction rate must not be reduced under load.
4. The motor has a relatively high rated power (e.g., around 100 kW), which can adversely affect the operation of the main transformer during operation.
5. The operation of motors in low-voltage switchgear is subject to strict voltage control, with current not exceeding 10% of the rated voltage (UE).
6. Low-voltage switchgear The machinery and equipment are highly precise, and there is no operational hazard upon startup.
7. Low-voltage switchgear has a small starting torque, making it suitable for full-load or loaded starts.
8. Large, medium, and small electric motors shall operate in an environmentally friendly and energy-efficient manner. From the perspective of initial project investment, for motors with a rated output power of 75 kW or less, it is more economically advantageous to use autotransformer reduced-voltage starter switchgear; for motors with a rated output power of 90–250 kW, switchgear is the more economical choice.
9. Short-term cyclical machinery refers to equipment that operates at full load for extended periods (with a load factor below 35%) but experiences frequent short-term light-load and high-load conditions, or equipment with intermittent loading, such as cranes, belt conveyors, metal composite sheet calenders, CNC lathes, high-speed punch presses, drilling machines, hydraulic shears, and the like.
10. The regulations stipulate that mechanical equipment used in operations must be equipped with features such as sudden rebound, stable acceleration, stable deceleration, rapid parking, low-speed braking, and precise positioning.
11. For long-term operation at high speed and short-term operation at low speed, when the load is less than 35%, using a switchgear delivers superior environmental and energy-saving performance.
Key Factors in Selecting Low-Voltage Switchgear
1. Cost considerations: While ensuring cabinet quality, it is self-evident that more affordable options in the same category will attract a larger customer base. Why, then, do some cabinets in the same category command higher prices while others are more economical? Some may argue that inferior raw materials result in lower-priced products with poorer quality, whereas pricier models offer better value for money. While these factors certainly play a role, the most critical determinant of cabinet pricing is the design and engineering approach. By adopting space-saving design principles and optimizing the layout, manufacturers can reduce material usage and production costs, thereby lowering the overall price of the cabinet.
2. Cabinet quality. A high-quality server cabinet can ensure reliable operation over long periods; by contrast, a low-quality cabinet not only fails to guarantee sustained performance but is also prone to frequent malfunctions and has a significantly shorter service life.
3. Cabinet Characteristics: Low-voltage switchgear The quality of these features directly impacts the cabinet’s operational efficiency; more efficient chassis cabinets will win widespread customer recognition and adoption.

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.
