Abstract

Oppfinnelsen angår en transformator, særlig en epoksyisolert transformator, med i det minste en underspeimingsvikling og i det minste en overspeimingsvikling. Ved hjelp av en anordnet elektrisk avskjerming rundt overspeimingsviklingen hindres speimingsoverslag, slik at tiansformatorens yttervegg kan berøres av en person og sikrer dessuten en elektromagnetisk avskjerming av transformatoren. Ved å bruke gjennomføringer til de indre elektriske tilkoblingene, er det mulig å anbringe en transformatoren utført ifølge denne oppfinnelsen i smussige omgivelser eller i fiiluft.
