| Production Description |
M.V. Surge Arresters are used to protect transformers and other equipments in station and distribution systems against the damage by atmospheric (especially lightning effects) and operational conditions.Metal oxides surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.
Apartarrayos de óxidos Metálicos con envolvente Polimérico. Cuentan con un menor tamaño y menor peso. Gran flexibilidad
de obtener los valores de distancia de fuga através de los faldones, acortando la longitud del cuerpo del apartarrayo. Su
envolvente de Silicón cuenta con una gran hidrofobicidad, resiste los rayos UV, limita las corrientes de fuga, elimina
los costos de lavado y permiten incrementar el tiempo de vida de estos equipos. Pueden ser utilizados en
ambientes altamente contaminantes.
