Basic Characteristics of Low-Voltage Switchgear

Low-voltage switchgear is a core piece of equipment in power systems used for low-voltage power distribution. It is mainly used for power distribution, control, and protection, and is widely used in power plants, industrial and mining enterprises, and building power distribution.

 

The main characteristics are as follows:

Rated Voltage and Frequency: The rated operating voltage of low-voltage switchgear is generally AC 380V or 660V, and the rated frequency is 50Hz. It is suitable for power distribution systems with AC voltage not exceeding 1000V.

 

Advanced Structural Design:

It adopts a modular and standardized design, supporting flexible combinations and facilitating expansion and maintenance.

The cabinet structure is available in two types: fixed and withdrawable. The withdrawable type facilitates maintenance and replacement, improving system reliability.

Internal functional compartments are isolated from each other, divided into functional unit compartments, busbar compartments, and cable compartments, ensuring independent operation of each part and improving safety.

 

Superior Electrical Performance:

It possesses strong breaking capacity, capable of withstanding short-time withstand currents of over 50kA, ensuring stable system operation during faults. Excellent dynamic and thermal stability, supporting three-phase four-wire or five-wire busbar systems, adapting to various power distribution needs.

 

High safety and protection level

Complies with national standards GB/T 7251.1 and IEC60439, and is a mandatory 3C certified product.

Protection level up to IP40, effectively preventing foreign object and electric shock risks.

 

Intelligent and environmentally friendly trends

The industry is developing towards intelligent, modular, and environmentally friendly material applications, supporting new energy grid connection, charging stations, and other new scenarios.

New products are equipped with temperature control and ventilation systems, and even adopt dual-fan collaborative heat dissipation technology to improve operational stability.

 

Wide range of applications
Can be used in metallurgy, chemical industry, data centers, rail transportation, hospitals, and other places with high power supply reliability requirements. In some scenarios, dual power supply is used to ensure critical loads.
