Xi'an Shendian Electric Co., Ltd. (hereinafter referred to as "Xi'an Shendian") is one of the designated domestic manufacturers of metal-oxide surge arrester, neutral grounding resistor, piezoresistor, surge protective device, resistor, cable accessories, tubular busbar, condenser bushing, composite insulator, epoxy insulating product, vacuum pressure impregnation product and other products. Xi'an Shendian is located at No. 23, Fazhan Avenue, New Industrial Park, High-tech Zone, Xi'an City, covering a site area of 19,000 m2 and gross floor area of 24,000 m2, and holding fixed asset amounted to RMB 200 Million. Xi'an Shendian currently has 330 employees, including 79 professionals and 20 experts who have made great contribution to China and are specialized in the design and manufacturing of surge arrester, resistor, cable accessories and epoxy insulation product.

Since its establishment in 1985, Xi'an Shendian has been in close cooperation with the relevant universities and colleges, scientific research institutions, the National Quality Supervision and Inspection Center of Insulators & Surge Arresters, and other institutions. With more than thirty years of production experience, Xi'an Shendian has established the production line of zinc oxide resistors and the production line of curing, forming, assembling and testing of silicone rubber products, both of which are at domestic advanced level. Moreover, Xi'an Shendian is equipped with skilled workforce, perfect technological facilities and complete production and testing equipment, mainly including tunnel furnace, spray granulator, water-bearing mixer, fully automatic hydropress, rubber mixing machine, curing press, fully automatic silicone injection and forming equipment, 1000kv or above extra-high voltage test station, partial discharge test equipment, fully automatic DC parameter tester, fully automatic square wave tester, residual voltage tester, AC and DC aging tester, high-current impact tester, X-ray real-time imaging system, salt spray / moisture test system, tracking test equipment, and helium mass spectrometer leak detector. All the equipment has high test accuracy and come up to domestic advanced level.


Xi'an Shendian mainly focuses on the development and production of 0.22 ~ 330kV porcelain- and polymer-housed metal oxide surge arresters, 5 ~ 1500V power-supply, signal, antenna-feeder surge protective devices, 0.4 ~ 1100kV resistors, 35 ~ 330kV transformer neutral grounding protective devices, counters and monitors, 1 ~ 220kV cable accessories, condenser bushings, epoxy insulating products, composite insulators and other products. Many of above products have been granted a number of national patents, such as composite polymer-housed metal oxide surge arrester, fully insulated surge arrester, line surge arrester with series gap,  touch-type over-voltage protector, neutral grounding resistor and resistors. Xi'an Shendian has independently drafted the Combination Type Metal-oxide Surge Arresters without Gas for the Three-phase AC Systems (JB/T10496) and the Combination Type Metal-oxide Surge Arresters with Series Gaps for the Three-phase AC Systems (JB/T10609), and also has participated in the drafting of 12 national and industrial standards. The products are designed in a reasonable mode, and have passed the type test and two-ministry (provincial) authentication, and their technical performance has satisfied the requirements of national standards and IEC standards. Xi'an Shendian also can design and manufacture the surge arresters and resistors of special specifications according to the user requirements.

While constantly pursuing the improvement of business operation mechanism, Xi'an Shendian has established a quality / environment / occupational health and safety management system in strict accordance with GB / T19001-2008, GB / T24001-2004 and GB / T28001-2007 standards to actively promoted 6S management. Xi'an Shendian has successfully passed the certification respectively of China Railway Construction Corporation (CRCC), China Intellectual Property Management System, Welding of Railway Vehicles and Components (EN15085-2), and International Railway Industry Standard (IRIS). It will make greater efforts to provide users with higher-quality and superior services.
