Kexun Electric Ships Batch of Medium Voltage Switchgear and Vacuum Circuit Breakers to Overseas Power Project

In October 2026, Kexun Electric completed another export order delivery at the Yueqing production base in Zhejiang, China. The order is centered on medium voltage switchgear, matched with withdrawable vacuum circuit breakers. After multiple production processes and strict factory inspections, the medium voltage switchgear and vacuum circuit breakers have been packed and dispatched for an overseas substation power distribution upgrade project.

The shipped medium voltage switchgear covers the 40.5kV rated voltage class. The switchgear cabinet is made of high-quality cold-rolled steel plate with compact structure and high protection degree, suitable for indoor substations and industrial power distribution sites. Inside the medium voltage switchgear, the vacuum circuit breaker serves as the core breaking component. The vacuum circuit breaker relies on the vacuum interrupter for fast arc extinction, featuring strong breaking capacity, long electrical life and low maintenance, and can reliably switch load current and short-circuit fault current.

During production, Kexun Electric applies standardized management to every process of medium voltage switchgear manufacturing. From sheet metal processing, busbar fabrication, component assembly to secondary wiring, each workstation follows clear technical requirements and inspection standards. Before installation into the medium voltage switchgear, each vacuum circuit breaker undergoes separate mechanical characteristic testing, loop resistance testing and withstand voltage testing to ensure the vacuum circuit breaker meets design requirements in operation and insulation performance.

At the factory inspection stage, the quality control team conducts comprehensive tests on each complete medium voltage switchgear, including main circuit resistance measurement, power frequency withstand voltage test, mechanical operation test and five-prevention interlock verification. Only medium voltage switchgear and vacuum circuit breakers that pass all test items can enter the packing and shipping process. Kexun Electric always regards product quality as the lifeline of the company, ensuring every exported unit complies with relevant IEC and GB standards.

For packing, Kexun Electric adopts professional moisture-proof, shock-proof and rust-proof packaging solutions for medium voltage switchgear to suit long-distance sea transportation. Precision components such as vacuum circuit breakers receive additional protective fixing to prevent displacement or damage caused by vibration during transit. Equipment model, weight, lifting points and moisture-proof marks are clearly labeled outside the packing cases for easy receiving and on-site installation by the destination client.

In recent years, Kexun Electric has continued to focus on the research, development and manufacturing of medium voltage switchgear and vacuum circuit breakers. Products have been exported to Southeast Asia, Africa, the Middle East, Central Asia and other regions. Besides standard medium voltage switchgear, Kexun Electric also provides customized complete electrical solutions according to client project requirements, covering ring main units, gas-insulated switchgear, metering cabinets and capacitor compensation cabinets.

The successful shipment of medium voltage switchgear and vacuum circuit breakers once again demonstrates Kexun Electric's overseas delivery capability. Moving forward, Kexun Electric will continue to provide high-quality medium voltage switchgear and complete electrical equipment for global power projects through reliable product quality, professional technical support and efficient delivery service, building long-term and stable cooperation with overseas clients.
