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

HD 464 S1 HD 538.1 S1 EN 60726 VDE 0532 ANSI C57.12.01

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;
