Single Phase Ac Spd

China Suppliers ICHYTI Wholesale single phase ac spd Quotation including I+II, B+C, T1+T2 types, with an Iimp of 12.5kA. The design purpose of these devices is to prevent indirect and low intensity direct attacks caused by lightning strikes. In the standard three-phase TN-C power grid, they can meet the requirements of LPL III and IV levels in EN 62305 standard, and can protect electrical equipment from the impact of lightning current. 

The total lightning current is 20kA, and the total lightning current is 20 or 40kA (based on physical configuration and mutual). At the same time, they should also consider the location of lightning rod grounding points, electrical installation grounding points, SPD installation locations and other factors. 

ICHYTI single phase ac spd Parameter (Specification)

ICHYTI single phase ac spd Feature

◉ Based on metal oxide varistor design.
◉ This design has low response time and Class I and II characteristics.
◉ If the service life of metal oxide varistor exceeds its service life due to high strength or frequent overvoltage peaks, the modular design with plug-in plug-in allows rapid replacement of functional modules.
◉ The shell is made of PC flame-retardant material, which has the function of fire prevention and insulation.

ICHYTI single phase ac spd Development history

The origin of surge protectors can be traced back to the late 19th century, when the initial horn shaped gap was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages. In the 1920s, aluminum surge protectors, oxide film surge protectors, and shot type surge protectors began to be applied. In the 1930s, tubular surge protectors emerged, and in the 1950s, silicon carbide lightning arresters emerged. 

In the 1970s, metal oxide surge protectors were introduced, and modern high-voltage surge protectors were not only used to limit overvoltage caused by lightning in power systems, but also to limit overvoltage caused by system operation. Since 1992, the industrial control standard 35mm guide rail plug-in SPD lightning protection module from Germany, France and other countries has been introduced into the Chinese market. Subsequently, integrated box power lightning protection combinations represented by the United States and the United Kingdom have also entered the Chinese market.
