Prestazioni elevate<\/h2>\n

Un buon esempio \u00e8 il trasformatore trifase da 100 kVA, utilizzato in Tanzania. Funziona a 11 kV sul lato dell'alta tensione per fornire una tensione costante di 0,4 kV sul lato della bassa tensione. Si tratta di un trasformatore efficiente, in quanto consuma solo 200 W di perdita a vuoto e 1580 W di perdita a carico, quindi ottimo per un utilizzo a lungo termine.<\/p>\n

Nucleo e avvolgimenti<\/h2>\n

Il nucleo \u00e8 in acciaio al silicio per ridurre al minimo le perdite; gli avvolgimenti sono in rame con isolamento per una conversione fluida ad alta efficienza.<\/p>\n

Olio per trasformatori - Due ruoli chiave<\/h2>\n

Isolamento: per bloccare eventuali perdite e consentire cos\u00ec di operare in sicurezza.
\nRaffreddamento: assorbendo il calore generato dalle operazioni di carico pesante.<\/p>\n

Capacit\u00e0 di sovraccarico<\/h2>\n

Di seguito sono riportati alcuni punti di interesse relativi alla capacit\u00e0 di sovraccarico.
\nAnche brevi periodi di sovraccarico possono essere facilmente gestiti da questi sistemi, perch\u00e9 sono affidabili e duraturi in un ambiente di alimentazione fluttuante.
