In 1998, the company was established in Xi’an, the beautiful ancient capital. At the beginning, it made up the development strategy of independent research and independent brand, the product was focused on the 10KV high-voltage current-limiting fuse for transformer protection, which passed type test in XIHARI and Tianshui Great Wall Experimental Institute one time and obtained model certificate with model identified as XRNT3A. In addition, it successfully passed ISO9001 quality management system certification of China Quality Mark Certification Center and adhered to the effective operation.
In 2000, the company began to develop motor protection, voltage transformer protection, oil-immersed backup fuses and dual sensitive fuse, capacitor protection and other current-limiting fuses, with various voltage levels within 3.6KV-40.5KV. The products were listed in the first batch of recommended directory in the transformation of national rural network.
It was the year when the company developed rapidly in 2007 through expanding plants, increasing production lines and further expanding the scale. Most of outsourcing processing was transformed into independent production. With vigorous development of China in the field of new energy and as required by major design institutes and manufacturers, the phenomenon of oil leakage in the transformer pool was completely solved in our products, and oil-immersed fuse for full range protection with the function of signal upload was successfully developed, winning a national invention patent, and successfully solving the practical use difficulty due to vast territory, severe environment and inconvenience for overhaul.
In 2008, China successfully held the 29th Olympic Games, and our products were successfully put into operation in the power facilities of swimming pool, basketball gym, cycling stadium, and anti-doping agency of the Olympic Games. In recent years, our company's products have become diversified, widely applied in areas such as network power supply, metallurgical and mining equipment, nuclear power and new energy.
In 2011, the company passed high-tech enterprise certification, and gained a number of national product patent certificates; it expanded overseas business, and various products were exported to Mexico, Angola, Myanmar, India, Indonesia, South Korea and other developing countries.
In 2013, the company first introduced high-voltage fuse with the function of temperature limiting with regard to the hidden danger brought by over too high temperature rise during the operation of enclosed switch cabinet, winning a national patent certificate and solving the malfunction caused by fusing due to high temperature rise. At the same time, the company made greater efforts to develop export business.
In 2015, the company continued to develop low-voltage fuses, outdoor fuses and other relevant fields. And it set up a low-voltage fuse production company (Xi'an Zhenli Nuobo Electric Co., Ltd.) which had a complete model of low-voltage fuses, and passed china compulsory product certification.
In 2017, the company successfully settled in the industrial base in High-tech District, Xi'an. It shares resources with Samsung power battery, Xinjiang TBEA, Xi'an Huawei and other well-known enterprises. It has independent plant, land and equipment, laying a solid foundation for long-term and stable development of the enterprise in the future.
