Established in 2013, part of Minsai Electric Group — manufacturing power distribution equipment from China's electrical capital.
Shanghai Jingmin Electric Co., Ltd. was established in 2013 and today operates as the foreign-trade and project arm of Minsai Electric Group Co., Ltd. We design, manufacture and export medium and high voltage power distribution equipment: switchgear, ring main units, box-type substations, vacuum circuit breakers, surge arresters, instrument transformers and cable accessories.
Our manufacturing base sits in Yueqing, Zhejiang — China's electrical equipment capital, where the whole supply chain is within an hour's drive. Our sales and export office is in Songjiang District, Shanghai, roughly two hours from Ningbo Port and three from Shanghai Port. That combination gives us both component-level cost control and fast, reliable shipping.
We are not a trading company. Enclosures, busbars, mechanisms, cores, windings and insulation parts are made and assembled by our own team, and final assembly and routine testing happen under our own quality system.
Vertical integration is the reason we can take on custom work that pure assemblers have to decline.
Cutting, bending, welding and powder coating of switchgear enclosures, substation housings and cabinets.
Vacuum interrupters, arrester varistor stacks, transformer cores and windings, CT/PT castings and cable accessories.
Primary and secondary wiring, busbar fabrication, interlocking and mechanism adjustment by trained fitters.
Routine tests on every unit: dielectric withstand, main circuit resistance, mechanical operation and interlock verification.
