Zhejiang Usune Electric Co., Ltd. is a professional factory in China specializing in the production of 12 kV, 24 kV, and 36 kV medium and low voltage switchgear. Medium- and low-voltage electrical switchgear panels are integrated, metal-enclosed electrical components. As core equipment, they are used for switching, controlling, protecting, and monitoring circuits of different voltage levels, ensuring the stable operation of power systems.
Voltage Level Classification
1. High-Voltage Switchgear
Suitable for 1kV and above (commonly 3.6kV–40.5kV), used in power grids, substations, and high-power industrial systems.
2. Low Voltage Switchgear
Suitable for ≤1kV (220V, 380V, 660V), used for building and commercial terminal power distribution.
Core Functions
Integrates five core functions: controlling circuit on/off, protecting lines and equipment (interrupting short circuits/overload faults), providing safety isolation for maintenance, real-time monitoring and metering of electrical parameters, and evenly distributing electrical energy to various loads.
Core Components
The Medium Voltage and Low Voltage Electrical Switchgear Panel utilizes high-quality, standardized components: circuit breakers, disconnect switches, grounding switches; contactors, relays, fuses; current/voltage transformers; busbars, cables, metering instruments; and control, protection, and communication modules.
Main Application Scenarios
The medium voltage and low voltage electrical switchgear panel is widely used in power systems (power plants, substations), industrial sectors (factories, petrochemicals, metallurgy), buildings (commercial buildings, residential areas, data centers), and infrastructure (railways, airports, new energy power plants).
Product Features
Compact and integrated structure, safe and reliable; strong short-time withstand current, excellent insulation performance; standardized design, convenient installation and maintenance; conforms to international standards such as IEC and GB.
Real-world Application Case
