What 杭州继保南瑞电子科技有限公司 does

Hangzhou Jibao Nanrui Electronic Technology Co., Ltd. (rebranded in 2022 to Hangzhou Jibao Electric Group Co., Ltd. / 杭州继保电气集团有限公司) is a privately held Chinese power-system equipment manufacturer founded in 2013 and headquartered in Yuhang District, Hangzhou, Zhejiang. The company designs and produces microcomputer-based protection devices — including anti-islanding, anti-reverse-power, transformer, motor, generator, line, busbar and integrated protection units — built around a DFT signal-processing pipeline running on DSP/FPU-integrated ARM microcontrollers with high-resolution analog-to-digital conversion. Its product portfolio extends into power automation systems (substation, distribution, hydropower, photovoltaic, wind power and PLC/LCU control), complete photovoltaic power-generation solutions including EPC and O&M, and complete or matching equipment sets for substations through 110kV.

The firm operates a manufacturer-direct B2B sales motion, supported by an 18,520 square-meter self-owned production facility with reported annual production capacity approaching 100M RMB, and serves utilities, renewable-energy developers, industrial and commercial power users, hydropower plants, and mining operators. Sales channels include a website with product and case-study content, SEO-driven search, online QQ consulting, and a direct sales/WeChat line, with a parallel franchise-dealer recruitment program. The company holds a stack of Chinese sector qualifications — National High-Tech Enterprise, Grade 3 Power Engineering General Contracting, Grade 4 Electrical Installation License, ISO 9001/14001/45001, and State Grid qualified-supplier status — and cites a reference base of more than 10,000 completed power system integration projects across 83 countries, anchored by named projects for State Grid Chizhou, China Nonferrous Metal Mining Group in Tajikistan, and distributed-PV customers in Anhui and Saudi Arabia. Pricing is quote-based and not publicly disclosed; revenue is generated primarily through one-time hardware sales and project-based engineering services.
