What Shanghai Liangxin Electrical does
Shanghai Liangxin Electrical Co., Ltd. (LAZZEN 良信) is a publicly listed (Shenzhen Stock Exchange: 002706.SZ), Shanghai-headquartered manufacturer of smart low-voltage electrical system solutions, operating since 1999 with between 1,001 and 5,000 employees. The company designs, manufactures and sells a comprehensive portfolio of low-voltage electrical components — including molded case circuit breakers (NDM series), universal/frame circuit breakers (NDW series up to 7500A and AC1500V), PC-level automatic transfer switches (NDQ series), isolating switches (NDG series), miniature circuit breakers (NDB series including IoT-enabled NDB5E), AC contactors and DC high-voltage contactors (NDC, NDZ3 series), overload relays, medium-voltage products (NDV/NDJN 12kV) and modular switchgear cabinets (NEA, NEA M, SEA) — together with the Smart Cloud Distribution Platform 3.0 that integrates these devices for predictive maintenance, energy management and carbon reduction. Revenue is generated through a mix of standard and customised hardware sales and B2B system-solution services, with no pricing publicly disclosed (quote-based model).
The company sells into real estate, new energy (photovoltaic, wind, energy storage), data centres, rail transit, industrial buildings, EV-charging infrastructure, medical and petrochemical facilities. Customer concentration is anchored in Chinese real-estate developers, with a nine-year strategic partnership with Vanke (A-class supplier covering 95% of Vanke low-voltage component needs across 65 cities and nearly 1 million residential units); additional marquee customers include China Mobile (Hohhot and Harbin hyperscale data centres), the Handan-Huanghua national-tier-one railway, Longyuan Jiuquan and Zhuhai Guishan wind projects, Qinghai Xitieshan 100MW solar project, State Grid's Beijing-Shanghai high-speed EV charging corridor (1262km, 50 stations), the 4th-generation Shidao Bay nuclear demonstration project (3000MW, RMB 42.3 billion) and Qingdao Oriental Movie Metropolis.
Go-to-market is direct enterprise field sales supplemented by a network of more than 50 switchgear-assembly partner firms ("成套厂") that bundle LAZZEN components into project tenders, supported by a 400-99-02706 technical support hotline and an investor-relations and brand presence on Weibo and WeChat. R&D intensity runs above 8% of annual sales. The company operates from a Shanghai headquarters plus a flagship Hangzhou Bay Super Factory in Zhoushan supporting its zero-carbon manufacturing positioning, and in March 2026 opened a Hangzhou Smart Home Experience Hall to extend the smart-home (Tianqi digital integrated box, Magic Panels co-developed with Vanke) offering into direct retail.
