Cooper (Ningbo) Electric Co., Ltd., a joint venture founded in 2007, is of strategic significance to Cooper Power Systems in the Asia-Pacific region. Located in the south wing of Hangzhou Bay Bridge and adjacent to China’s largest industrial city Shanghai, it is a well-known enterprise specialized in the production of low and medium-voltage switchgear and medium-voltage components.
In the field of medium-voltage power transmission & transformation equipment manufacturing, the company boasts world-class manufacturing mode and management mechanism, and has set up world-leading production lines for assembly and automated testing of vacuum circuit breakers, production lines for the lean production of intelligent switch cabinet and full-automatic production lines for flexible processing of metal plates. Moreover, it owns high-quality testing equipment, making possible the line production of complete switchgear and circuit breakers. In terms of manufacturing, it implements fine management mode, and carries out the ERP management techniques, SAP, MVP, DMVP, and MD innovation and advanced management system, thereby realizing the comprehensive IT-based management from product development, engineering design, manufacturing to after-sales services.
Based on Cooper’s global R & D platform, the company has established Edison (Ningbo) R & D Center to share the global R & D resources of Cooper. It introduces and absorbs Cooper’s world-leading solid sealing technology, control technology, permanent magnet technology and on-line detection technology, and adopts state-of-the-art production equipment and technology to boost its efforts in product innovation. Currently, it has obtained two patents for inventions and nearly 20 patents for utility models.
The VN and CE series vacuum circuit breakers independently developed by the company adopt modular spring operating mechanism, Cooper’s low resistance vacuum interrupters and solid sealing technology. It sources oil buffers, springs and core components globally. The company has established the assessment system for qualified sub-suppliers, and extended the quality management, guaranteeing its product quality.
Product assembly is realized through a dedicated production line, with fixed positions, a set number of staff, timing, fixed stations, set tools, set assembly requirements, and set testing requirements. Through the above, it ensures that a dedicated person is responsible for each procedure and the quality traceability system and files have been established. World-leading testing equipment is harnessed for periodic metrological verification to ensure the effectiveness of detection. The assembly plants adopt fully enclosed operating environment with a constant temperature, and use special equipment for lifting, transfer, and flip operations, etc., in a bid to reduce labor intensity and ensure safe operation.
Our main products include: switchgear cabinet, vacuum circuit breakers, contactors, intelligent power solutions, etc. Products are manufactured as per Chinese and international standards and specifications such as GB and IEC, ensuring that products are of leading technology and caliber in the industry. The products have been applied to such sectors as power grid, power generation, petroleum, petrochemical, metallurgy, rail transportation and infrastructure. The company has set up after-sales service outlets in nearly 30 provinces and municipalities in China and exports products to Singapore, Malaysia, Thailand, Australia, Vietnam, and the Philippines, etc.
