Series EVT/ZW32–10 voliyumu thiransifoma ndi mtundu watsopano wa kuyeza voteji mkulu ndi thiransifoma chitetezo, makamaka yofanana ndi panja ZW32 vacuum circuit breaker.Ma thiransifoma ali ndi ntchito zamphamvu, mawonekedwe ang'onoang'ono a siginecha, safuna kutembenuka kwachiwiri kwa PT, ndipo amatha kulumikizidwa mwachindunji ndi zida zachiwiri kudzera pakusintha kwa A/D, komwe kumakumana ndi chitukuko cha "digito, anzeru ndi maukonde" ndi "integrated automation system. ya substation".
Kapangidwe kake: Gawo lamagetsi la ma transformer awa limagwiritsa ntchito capacitive kapena resistive voltage division, epoxy resin casting, ndi manja a mphira a silicone.
