Since 1929 Siemens has been manufacturing high-voltage surge arresters with porcelain housing for standard and specialized applications. Permanent research and development and the concerted know-how in the Siemens factory give 3EP6 surge arresters a leading edge in overvoltage protection. Uncompromising quality ensures the long service life and reliability of each application. In general, Siemens arresters are used to protect high-voltage equipment in substations, such as transformers, circuit breakers, and bushings, for example. However, apart from the area of standard applications, Siemens offers the 3EP6 surge arresters for any application up to 550 including special applications such as high-voltage direct current (HVDC) systems or all kinds of compensation systems for electric power networks. Furthermore, Siemens surge arresters have been designed to meet the requirements of a wide range of common installation environments, from arctic cold to the heat of the desert and the dampness of tropical climates. Advantages of 3EP6 surge arresters Excellent overvoltage protection and large worldwide experience High mechanical stability For networks with short-circuit currents of up to 65 ka Maximum protection in case of overload through directional pressure relief device Decades of trouble-free service life without failures or ingress of moistures thanks to the excellent sealing system Suitable for system voltages of up to 550 Brown or gray porcelain designs The following table shows the order numbers of the 3EP6 standard porcelain surge arrester. For additional options/ specifications just contact Siemens or your nearest Siemens partner. We can supply arresters with higher rated voltages and continuous operating voltages, with higher or lower residual voltages, and with longer or smaller creepage distances are also available. 2
