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.
Suitable for 1kV and above (commonly 3.6kV–40.5kV), used in power grids, substations, and high-power industrial systems.
Suitable for ≤1kV (220V, 380V, 660V), used for building and commercial terminal power distribution.
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.
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.
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).
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.
Usune provided a complete set of 12kV medium-voltage and 0.4kV low-voltage switchgear equipment for a new energy photovoltaic power plant in eastern China. This equipment operated stably for two years in a complex outdoor environment without major failures, ensuring stable grid connection of photovoltaic power and receiving high recognition from the project owner and power grid management department.
