Abstract: Metal oxide varistors (also known as ZnO based varistors) are today used for making state of the art surge arresters for all voltage levels, but they are less used for telecommunication lines. Essentially they are “n” semi-conductor ceramics made of ZnO (more than 90%) and many other oxides having different roles. This paper presents a new manufacturing technology based on 2 additional oxides Cr2O3 and MnO2. This varistor material has a smaller electrical capacity, suitable for telecommunication applications. Started from chemical measurements, and finished by electrical tests, the experimental pat of this paper is an Interdisciplinary research.
Keywords: metal oxide varistors, telecommunications
