Installation and use
1. When mounting the fuse into the tank, ensure the oil level is within the range as shown in Fig. 2
2. When replacing the fuse, open the buckle on the handle and turn the handle for 90° to eliminate the adhesion between the sealing gasket and outer tube. Remove and replace the handle.
3. For the installation of three-phase fuse, replace all three phases unless you can confirm that the fault current passes through one phase.

Founded on March 7, 1998, Shaanxi Zhenli Electric Power Technology Co., Ltd. (formerly known as Xi'an Zhenli Fuse Co., Ltd. ) was located in F4-402 Lutong Industrial Park, East Section of Kuangshan Road, East Er'huan, Xi'an with the industrial plants covering 1771.08 square meters. As the company business gradually expanded, it was moved to No 2055, Shanglinyuan No. 5 Road, High-tech District, Xi'an in 2017, with three self-built standard plants covering 20847.26 square meters and a total of 80 staff including 8 research staff, 6 professionals and 6 product designers. As required by High-tech District of Xi'an, the company was restructured into Xi'an Xiangyuan Zhenli Electric Co., Ltd., a high-tech enterprise specialized in research and development, production and sales of indoor and outdoor fuses whose production scale and technical level lead the industry in China. So far, the number of fuses running in the power grid in the world is more than 3 million and the company has rich experience of line operation. Its products cover the voltage within 3.6~40.5kV and the current within 0.2A~315A. Its main products belong to new-energy wind-photovoltaic power hybrid power generation system strongly supported and developed by the nation. Currently, its main clients are Schneider, ABB, TBEA, Shandong Taikai, Jiangsu Huapeng and other Top 500 enterprises in the world and listed companies in China. The products are sold as far away as Portugal, Thailand, Mexico, Pakistan and other countries.
