Wuhan NANR Electric Co., Ltd. (former name is Wuhan Nanrui Electric Co., Ltd) was founded on July 1, 2008, with a registered capital of 32 million. Due to the requirement of business promotion, our company name had updated as Wuhan NANR Electric Co., Ltd. in 2020, our business and development model remain unchanged. After changing company name, we have more market vitality and brand effect. For more than ten years, our company has developed as a high-tech enterprise integrating scientific research and development, technical consulting, equipment development, production, sales and engineering services.
Our main products are AC/DC Voltage Divider (high accuracy can be up to 0.1%), Pulse Voltage Divider, DC High Voltage Generator (DC Hipot Test Set), DC Withstand Voltage Test Set for Generator, Partial Discharge Test Equipment, High Voltage Probe, Resonant Withstand Voltage Test Device, Transformer Test Set, cable test set, CT/PT Test Set, Relay Test Set, etc. The products are widely used in power supply bureau, power grid substation, electric power research institute, calibration institutions and qualified installation, repair and test enterprises. We have carried out extensive scientific research cooperation and technical exchanges with Wuhan University, Huazhong University of Science and Technology, Wuhan University of Technology, Tsinghua University and other domestic well-known universities, and launched a large number of advanced technology and reliable test equipment.
Technological innovation is the source of power and development of an enterprise. Through continuous independent innovation, our company has achieved a large number of high-level scientific and technological achievements with independent intellectual property rights.
Our company has successively obtained ISO9001: 2008 GB/T19001-2008 Quality Management System Certificate (certificate number: 0011Q210845R0S/4200); CE Certificate (certificate number EN60950-1: 2006 +A2: 2013); Registration certificate of Declaration for Inspection and Quarantine Enterprise (registration number: 4200605473); Our company was rated as "contract-abiding and trustworthy enterprise" by Wuhan Administration for Industry and Commerce and Wuhan Contract Credit Promotion Association in 2012 and 2014-2015 respectively; the registered trademark "NANR" was recognized as a famous trademark of Wuhan  by Wuhan Administration for Industry and Commerce From 2015 to 2017 (Registration Number: 4200605473).
Our company pays more attention to the research and development of new products, has obtained a number of patent certificates, some of patent certificates shown as follows:
1, High voltage divider with reliable shielding performance, patent No.: ZL 2012 2 0355014.1;
2. DC high voltage generator, patent No.: ZL 2012 2 0391370.9;
3. Resonant withstand voltage test device (NRXZ), patent No.: ZL 2016 3 0485826.1;
4. Leakage current tester for water cooled generator (NRZV), patent No.: ZL 2016 3 0554223.2;
5. Dry type air-core high voltage resonant reactor, patent No.: ZL 2017 3 0659991.9;
6. Dry type air-core high voltage resonant reactor, patent No.: ZL 2017 2 1816162.8;
7. Intelligent DC high voltage generator, patent No.: ZL 2018 2 1598949.6;
Our company produced many products with strong market competitiveness and won the praise from customers. Among them, NRV series high voltage probes break the embarrassing situation that no company can produce in China for a long time, and solve the current situation of domestic long-term dependence on imports; The AC / DC standard voltage divider with 0.05% and 0.1% accuracy developed by our company has the leading technology level in China and is widely used in Electric Power Research Institute as the measurement standard; The series resonant withstand voltage test device developed by our company can realize the parallel operation of multiple variable frequency power supplies, which is the first in China; The intelligent DC high-voltage generator produced by our company can achieve automatic boost, automatic test of zinc oxide arrester, and can be connected to PC, which is controlled and operated by upper computer software. In addition, the UHV voltage can reach 60-1600kv, and the UHV output current can reach about 500mA, which fully realizes the full coverage of the DC high voltage generator; The DC high voltage generator for water-cooled generator independently developed by our company adopts the control mode of 8.4-inch touch screen and digital rotating mouse, and has the functions of automatic voltage boosting, data storage, data printing, etc., so as to realize the true intelligence.
Our company adheres to the development concept of people-oriented and product quality first, and provides customers with more reliable, more accurate, and more intelligent products. Customer satisfaction is our service tenet.
