Kexun Electric Strict Production & Testing Process For Medium Voltage Switchgear Delivery

Kexun Electric owns a complete production workshop for medium voltage switchgear and vacuum circuit breakers at Zhejiang Yueqing production base. Kexun Electric follows fixed production standards for all manufacturing steps of medium voltage switchgear.

Component preparation is the first step of medium voltage switchgear production. Kexun Electric selects qualified raw materials and core components including vacuum circuit breakers, busbars, earthing switches and protection relays. Every incoming component will be checked before entering assembly workshop.

Technicians of Kexun Electric carry out medium voltage switchgear assembly strictly according to drawing requirements. Technicians install internal components, complete wiring and mechanical adjustment. The five-prevention interlock structure of medium voltage switchgear will be debugged in this stage to guarantee safe operation.

After assembly work, all medium voltage switchgear products enter professional testing station. Kexun Electric implements complete factory tests including loop resistance test, power frequency withstand voltage test and interlock function test. Only medium voltage switchgear that passes all test items can move to packaging procedure.

Qualified medium voltage switchgear will adopt moisture-proof and shockproof packaging. Kexun Electric arranges loading and shipment after packaging. Kexun Electric tracks logistics status to make sure on-time delivery for global power and substation projects.

Kexun Electric supplies reliable medium voltage switchgear, vacuum circuit breakers and related power equipment complying with IEC standards. Kexun Electric keeps optimizing production and inspection system to support more overseas power distribution projects.
