Clients can freely select and assemble over 200 component options to form different framework structures and drawer units, precisely matching their power distribution needs.
This modular design not only maximizes space utilization—accommodating more functional units in a relatively compact footprint—but also simplifies on-site installation and future expansion. When industrial plants need to upgrade production lines or adjust load distribution, the switchgear can be easily reconfigured without large-scale modifications, significantly reducing downtime and renovation costs.
2. Superior Safety Performance for Industrial Environments
Industrial plants are often faced with harsh operating environments, such as high temperature, humidity, dust, and even corrosive gases, which pose severe challenges to the safety of electrical equipment. CHBEST Power prioritizes safety in every aspect of switchgear design and manufacturing to ensure reliable operation under extreme conditions.
The enclosure protection rating of the switchgear can be customized according to specific environmental requirements, with options ranging from IP40 for general indoor use to IP54 for damp or dusty areas, effectively preventing the intrusion of solid particles and water. The cabinet body is made of high-strength flame-retardant cold-rolled steel with a thickness of 2.0-2.5mm, undergoing acid pickling, phosphating, and electrostatic spraying treatments to enhance corrosion resistance and mechanical strength. Internal components adopt high-quality flame-retardant engineering plastics, and low-smoke halogen-free (LSZH) cables are used to minimize fire risks and toxic gas emissions in case of accidents.
To ensure personal safety, CHBEST Power's switchgear is equipped with electrical interlocking devices that automatically cut off the control circuit when the cabinet door is opened. All live parts are enclosed by insulation covers or partitions, and the cabinet frame is reliably grounded with copper braided belts of no less than 25mm², ensuring a grounding resistance of ≤4Ω. These safety designs effectively prevent electric shocks, short circuits, and other electrical hazards, safeguarding the lives of on-site operators and the integrity of production equipment.
3. Excellent Electrical Performance and Stability
Industrial plants often have high demands on the breaking capacity, dynamic thermal stability, and voltage regulation performance of low voltage switchgear, especially for heavy-load equipment such as motors, pumps, and fans. CHBEST Power's switchgear is designed to meet these rigorous requirements, with rated voltages covering 380V and 660V, and rated operating currents of horizontal busbars ranging from 630A to 5000A.
The main busbar adopts a copper bar insulation support structure, with cross-sections carefully calculated to ensure a temperature rise of ≤60K under an ambient temperature of 40℃. The rated short-time withstand current of the horizontal busbar reaches 50-100kA (rms for 1s), and the peak current reaches 105-250kA, enabling the switchgear to withstand the impact of short-circuit currents and maintain structural integrity. Advanced circuit breakers and protective devices are integrated to achieve fast and accurate overload and short-circuit protection, cutting off faulty circuits within 0.1 seconds to avoid damage to core production equipment.
