Electrically insulating surge arrester / type 1 - max. 1 200 kV
Since Surge Arresters are a crucial support for coordination insulation for electrical power supply systems since the expensive equipment has to be protected against over voltage while switching and lightning. In these cases, Surge Arresters of Metallic Oxide material are the perfect solution for over voltage protection if the basic rules are followed plus they have a lifetime of nearly 20 years and almost 0% failure rate. Surge arrestors, being good in performance, are equally good in cost efficiency as well, costing only a mere 1% of the total equipment that they protect in electrical power supply systems. Their availability is good, and hence they are the obvious choice for quality improvement in the electrical power supply systems and their benefits make them compatible for use in other applications as well.
