Abstract
Flangia caratterizzata dal fatto di essere di per sé già isolante in modo da poter essere accoppiata ad altra normale flangia, avente uguali dimensioni facciali, in modo isolato elettricamente senza dover ricorrere al tradizionale impiego di disco isolante interposto fra due flange normali e dover isolare da queste i bulloni e dadi di serraggio con l'impiego di bussole e rondelle isolanti.
