Xi'an Shendian Electrical Appliance Co., Ltd. is one of the designated manufacturers of domestic metal oxide lightning arresters, high-power resistors, cable accessories, tube busbars, dry casings, epoxy insulating products and vacuum pressure impregnating products. Located at No. 23, Development Avenue, New Industrial Park, Xi'an High-tech Zone, covers an area of ​​87,000 square meters, a construction area of ​​60,000 square meters , and has fixed assets of 500 million yuan. There are 60 senior engineers, 86 experts in design and manufacturing of lightning arresters, resistors, cable accessories and tube busbars, 13 master's students and 1 doctoral student. Over the years, the company has adhered to the corporate spirit of "pursuing excellence" and has won a wide range of domestic and foreign markets, including petrochemical, nuclear power, wind power, metallurgy, coal, high-speed rail, subway and other fields. With its excellent product quality and performance, it has become a country. Qualified suppliers of well-known domestic companies such as the Power Grid, China Southern Power Grid, Sinopec, CNPC, and China Railway Electrochemical Bureau, as well as global qualified suppliers of internationally renowned companies such as ABB, Siemens, Schneider, Toshiba, and Mingdianshe.

Since its establishment in 1985, the company has maintained close cooperative relations with universities and research institutions such as Xi'an Jiaotong University, Huazhong University of Science and Technology, Tsinghua University, Xi'an High Voltage Electrical Appliances Research Institute, China Electric Power Research Institute and other institutions. Gathering more than 30 years of production experience, we have formed a zinc oxide resistor sheet production line with advanced domestic level, a silicone rubber product vulcanization, molding, product assembly and testing production line. We have a skilled staff, complete process and equipment, production and testing equipment complete. Mainly includes rotary tunnel furnace, spray granulator, water-containing mixer, fully automatic hydraulic press, glue mixer, vulcanizer, fully automatic silicone injection and molding equipment, million-volt ultra-high voltage test station, 1500kV power frequency series resonance set Equipment, 3600kV lightning shock complete set of equipment, 1200kV ultra-high voltage DC voltage generator, partial discharge testing equipment, fully automatic DC parameter tester, fully automatic square wave testing equipment, residual voltage testing equipment, AC-DC aging test equipment, high current impact test Equipment, X-ray real-time imaging system, salt spray/wet test system, leakage trace test equipment, helium mass spectrometry detection equipment, etc., have high test accuracy and all reach the domestic advanced level. To date, Xi'an Shendian is a domestic enterprise that can produce 2mS square wave impact current of 4000A metal oxide resistors. All 1000kV ultra-high voltage transmission lines have been built in China and use this resistor to assemble and operate ten times. There has never been an accident in the rest of my life, and the protection is very reliable.
