Dry Type Cast Res n Transformers
Features Low nstallat on costs
The transformers can be nstalled near the load No need for o l collect ng p ts. No fire barr ers No special building work Low operat on costs
Low losses Since cast res n transformers dont have
o l, there s no need for check ngref ll ng or replac ng.
Cast res n never r equi res expens veclean- up s.
Env ronment Fr endly No liquid s, thus no r sks for leakage No tox c or corros ve gases, or halogens
No Ma ntenance s requ red The only prevent ve ma ntenance s
visual check High confidence
Excellen t insul at on aga nst short-c rcuitand l ghtn ng
Highresistance against humidity. Short-t me overload capac t y much great er than liquid-filled t ransformers. For longer overloads, forced cool ng AF
(40%) is an option just by add ng fan assembly
StandardsBEST Dry Type Cast Res n Transformerscovers the follow ng nternat onalstandards: IEC 60076-11

Safety
Hardly nammable, self-ex tinguishing Cast res n transformers are f re res stant In case of a short c r cuit, cast res n
transfor mers will not cause big damage They are not self- gn t ng and therefore cannot be the cause of a fi re;
