1 Transmission Porcelain Surge Arresters ENERGY DIVISION

2 Porcelain Surge Arresters Porcelain surge arresters are available for applications up to 400 systems. Porcelain housing designs have been used by us for over 55 years. From 1945 we produced porcelain surge arresters to the gapped silicone carbide pattern and since 1980 we have produced arresters to the gapless ZnO design. The design consists of porcelain housing which conforms to IEC-815 with an Aero Dynamic shed profile. The varistors, spacers and locating rings are assembled under compression with pressure relief diaphragms at either end. The air void is evacuated and replaced with dry air, then sealed. Routine tests are carried out to show that the manufacturing conforms to the current International standard.
