Nanyang Jinguan Electric Co., Ltd. (JinguanElectric® reGIStered trademark), established in 2008 and headquartered in Nanyang, Henan Province, China, is a professional global supplier specializing in high-voltage power protection equipment.
We specialize in supplying complete ranges of metal oxide surge arresters (MOA), metal oxide varistors (MOV discs), and dedicated protection devices for railways and new-energy charging stations, with voltage classes from 3kV to 1200kV, fully covering AC, DC, railway, wind power, solar, and UHV applications.
With more than 15 years of deep engagement in international markets, we have successfully delivered reliable over-voltage protection solutions to over 80 countries and regions across Europe, the Americas, Southeast Asia, the Middle East, and Africa, serving hundreds of high-speed railway, wind farm, UHVDC transmission, and urban distribution projects worldwide.
We maintain long-term strategic partnerships with numerous renowned global power companies. All products are type-tested and certified by internationally recognized laboratories including KEMA, CEPRI, and STL members, and fully comply with the latest IEC 60099-4, IEEE C62.11, and GB 11032 standards.
Our MissionTo be the most trusted global partner for power protection solutions, ensuring every kilowatt reaches its destination safely.
We specialize in supplying highly reliable over-voltage protection solutions to customers worldwide. All products are type-tested and certified by internationally recognized laboratories (KEMA, CEPRI, STL, etc.) and widely used in substations, high-speed railways, wind farms, solar plants, UHVDC transmission and urban distribution networks.
Designed to protect high-voltage lines and equipment from lightning and switching over-voltages under all global climate and environmental conditions.
